How to fix a low water pressure and flow problem on a brand new build house.
As you will see in this video the water pressure on this house is really bad, to the point of the shower upstairs doesn’t even work… it dribbles out of your lucky.
Water flow rate upstairs is around 3/4 litres a minute... this is how to fix the issue
Fitting the Salamander Home Boost Main booster solves the problem and now the house has the water and flow rate it should have….. 12litres a minute…

I would have checked the flow rate without the stop tap on. I work on many new builds, seen main stop taps full of stones and grit. Even had a situation like this, and it was to a blocked water meter in the boundary box.
That shower was a joke, I’d have been back into the builder to sort that at least! Jokers
Oh mate, I’ve tried, phoned, my lad has phoned and nothing…..
I'm surprised you bothered reinstalling the pressure reducing valve it just seems like a flow restriction considering the pressure was so terrible.
Just incase for some reason they turn the main up in the future👍🏼👍🏼
Good video 👍 you might have just saved me a few quid by thinking about changing my combi! What’s the cost of these pumps? Struggling to find it on their site.
Do a Google search buddy, they will come up👍🏼👍🏼
You should charge that work to the house builders disgusting …
I will be buddy 👍🏼👍🏼
Not likely they haven’t set the main pressure at the street income being that the development isn’t finished yet?
@@Mr_Ashley I was thinking the got some small bore pipe as bypass feeding the main supply to a few streets that aren’t fully finished, accounts for the pretend 1.5
@@MJTiffPlumbingplus the price of running the pump forever. 😂
Hi, I have the same Salamander booster fitted on the main but boost the water pressure because my water softener doesn’t work without the pressure. Since the plumber connect booster when I on the electric switch it doesn’t work with booster and I have no clue what’s wrong. Is it a brand?new booster. I am wasting all my money on plumbers but couldn’t sort of the problem yet. I really don’t know who to trust. I really need a help
That’s really bad ,can you tell me would that booster help me as when I have shower on that runs off combi ,works fine when nothing else is turned on but say if a tap is turned on some where else it really affects the pressure on the shower
Yep, that would work fine with this fitted
@@MJTiffPlumbing ok thanks for that like I say pressure isn’t to bad but only when you call for water off 2 things same time,will look into fitting one of these
I hope you gave the builder your bill!!
They are being so bad with this…. I am taking it further
I actually work at salamander pumps and to see this pop up as a recommended video is pretty cool! nice to see our product is proving good use for your family!
Nice one mate….. yer the salamander team is great, I was with them last week at Installer Show👍🏼👍🏼
Evening Mark. Seems to be a common theme, new builds & really poor mains pressure. You may well end up fitting a few more of those Salamander's once your sons neighbours see what he's got! I've given up using brass olives now for that very reason you've encountered. Always try and use copper olives now, especially 22mm.
Yep I think I may very well be, what a massive improvement👌🏼👌🏼
I have been throwing out brass olives and putting in copper for years except on chrome. Just a shame generally I have to buy them online
Really interesting to hear that it seems to be a big problem in new builds!
That pump looks brilliant but wouldn't expect that sort of pressure in a new build! Be interesting to see comments what minimum pressures should be 👍🏼
Pump is great 👌🏼👌🏼
A problem which would have to be fixed by the builder under warranty.
Look on the bright side, you could have a whole new build estate to install boosters 👍
Hahaha very true
I would of knocked the doors of the neighbours and asked them what their water pressure/flow rates are like. I can’t see how that’s passed snagging? Surely the incoming mains is kinked or damaged in some way.
I have buddy….. spoke to all the neighbours and they are all the same.
Developers don’t want to know… so bad
@@MJTiffPlumbing that’s really bad. They have an obligation for 1bar working pressure and 9 litres per minute. Once the sites done and temporary water supplies are disconnected hopefully it will rise?

Guarantee if you'd have done away with that PRV you'd have achieved the same outcome! Why have a PRV on a supply that only has 15 meters head coming in in the first place. They are a constant issue and are almost always the problem. Pumps only really work on a tanked system. How can you increase pressure when the incoming pressure is determined in the main. There should never be poor flow on a 25mm MDPE service. There is obviously a flow restriction!
Guaranteed it didn’t….. and as you can see from the video the pump worked a treat and now the supply is how it should be👍🏼👍🏼
@@MJTiffPlumbing trouble with plumbers these days is that they don't understand the science behind the water. You can't just magic up pressure. The pressure is determined in the main and no pump will make a difference. You've basically just spent 100's of pounds to remove a flow restriction. See it multiple times per week
The pump activates when the water flow rate reaches 3 litres per minute, it recognises this using a turbine, and boosts the water flow to 12 litres per minute.
@@SalamanderPumps not disputing how your pump works but the fact that there was 3 litres per minute at a new build property suggests that there is a restriction in flow simply down to the fact that if it was actually that amount being pumped in then not only would all the properties in the street be affected but the water undertaker would not be meeting the standards of service that Ofwat outline. In my area (North West) the dynamic pressure and flow standards are 9lts of flow at 1 bar pressure. This guy has fitted a pump instead of finding the root cause of the problem. Either the PRV is defective or there is a restriction somewhere further back on the MDPE service. Possibly squashed somewhere restricting the flow. Usually poorly ducted at point of entry.
@@johnmac6568 Appreciate where you’re coming from. In this instance trying to resolve the low water flow issue through other avenues didn’t work, thankfully HomeBoost offers a solution that’s quick and easy to install and overcame the homeowner’s water pressure problems. Thanks
Absolutely shocking!
Quality of new builds these days is unbelievable. I'd take a nice old victorian house over the crap they shoveling out these days. Just a shame all the first time buyer schemes only let you buy new builds.
They should start fining these companies every single time they hand over a property with defects, they'll soon sort it out then. Right now there's just no consequences for them so they'll keep doing it until something finally drops. Some of the defects they get away with are downright dangerous.
Glad that pump works so well I'm well impressed by that. Great job 👍
Yep give me an old house every day👍🏼👌🏼
After 30 years using press mate you learn over time to crimp sections up then offer the section up and crimp one joint in place when it’s in tight places 🤘😎🤘
Cheers buddy…. I’m getting to grips a bit more with it
@@MJTiffPlumbing I like what you did there 🤣😂🤣😂🤣😂🤘😎🤘🫖☕️🍰
Complain to the water supply company / developer.. why the extra expense on a new house?
Oh trust me I did and got no where
If I bought a new build and my shower and pressure was that bad I would ask for it be fixed by the housing company immediately,I would not spend a penny on it.
Do you think we didn’t try…. Trust me…. They didn’t want to know
Now you will find all the leaks on that shower ❤
Don’t say that 🤣🤦🏻♂️🤦🏻♂️
I bet you’ll get asked to go to all them properties
Hahaha let’s hope so
Been waiting for this video. The results are excellent. Like I have said before its not just new builds that struggle. Will have a word with my plumber about this. Great video Mark thanks
Great outcome wasnt it buddy 👍🏼👍🏼
@@MJTiffPlumbing Another freebie Mark. LOL
Thanks Nigel - @MJTiffPlumbing has done a brilliant job of explaining and demonstrating HomeBoost!

Hi!!! Informative video thank you!!!!
But please don't kill the birds we need them😊
Feed two birds with one fig instead❤😊
Glad you liked the video
Couldn't you take the pressure reducing valve out? Or would that invalidate the new build warranty?
It’s fully open so makes zero difference 👍🏼👍🏼
@M J Tiff Plumbing I heard you say it was open fully, just thought there was no point keeping it.
I follow how the pump will overcome the system restrictions to increase flow to the upper floors but I don't understand how this pump can increase the flow rate of the incoming mains - makes no sense!
But it does 👍🏼👍🏼
Hi are you based in London? What’s your number? Can you put a water pressure to increase my bar from 1 to 4? Also can you put a osmosis filter in the same mains?
No sorry
why is there a need to fit that pressure reducing valve when the pressure is so low?
Incase they sort out the main and it becomes very high👍🏼
If you have 3 bar in the street and 3 bar at the tap, but flow is ~10l/min, but due to lead pipe to the property, would a pump still give better flow rate?
Yep would give 12l per min
It sounds like the lead mains is restricting the water supply, which is why you have high pressure but low flow. HomeBoost will boost the water up to 12 litres per minute, as you’re already getting 10 litres per minute, this might not be the solution for you. We would recommend choosing a product from our new range ‘TankBoost’ which is ideal for your situation.
@@SalamanderPumps thank you, it might well be cheaper to replace the lead pipe for our needs.
Why do you need to re-fit the reducing valve when the pressure is low? I don’t have one on my setup as incoming mains pressure is only 2 bar
Incas the pressure is ever turned up… we know it will be at 3bar max
It’s garbage these new builds my daughter had blocked drainage from the bath brand-new
Ain’t they just
Is the noise disturbing a lot ? Can't have this whining up in my kitchen.
.
Can hardly hear it
Why you even fitting that it’s got a guarentee on the house get hsb on it gets me how they put it all in 22 aswell and a prv on it 😂 also house is piped in plastic so 15mm plastic is like 10 now after inserts
Min a bar pressure and flow rate of like 9-10 or something
They didn’t want to know…..
Wonder what it’s like with 2 taps running at the same time?
Exactly the same mate…. 12l per minute 👍🏼
Liters/minute? That can't be right
It is mate…..
Legal min is 1 Bar & 6 ltr per min at the outside stop tap.... would have been better to take the PRV off, doubt very much its going to need it!
But you never know, if they turn the main up you need the PRV 👍🏼
Does this booster have the same effect when you have a dishwasher a washing machine and a shower on at the same time?
Indeed it does mate
i like your comment when you said you can just about hear it sound like gonna take off lol will that boost work if 2 showers are running as my mains pressure is fine if one bath or shower is on but when both are on pressure drops would that help
Still holds 12L per min….. it’s a great product👍🏼👌🏼
HomeBoost will boost the mains to 12L/min but this'll be shared across all open outlets, so if 2 showers are running they'll each received approximately 6L/min.
Why is the PRV before the boost. Makes no sense to me. There was no house pressure to begin with
Has to be fitted now on new builds…. Also in place incase the pressure is lifted at a later date buddy
Need plastic surgeon on the bottom of that cupboard buddy! New build eh? Very neat install, great work 😊
Brand new……🫣
If your sons place is like this the entire estate probably is. We come across it a lot in Sussex where they haven't turned the local boosting station on yet due to the sites not being complete or when they have they haven't flushed the mains so the filters on the pressure reducers are clogged.
For anyone wondering why the pressure regulators are put in it's due to warranty on the fittings in the property. They can't comply with NHBC scheme if they don't put the relevant measures in place, sadly they will still try to worm their way out of ever paying out for messing up on new builds.
Yep… they tick the boxes so that they then don’t have to come back it seems
Curious , what did the customer say , after you fitted it , and then used it at a high demand time of the day for the estate ?
It’s perfect, it’s at my sons house and it’s been perfect
Is there a pressure regulator outside houses as my neighbours have better pressure
Nope
At least your sons new build has copper pipes. Went to one last week and under sink was all plastic.
Very true that mate
Hi mate, i live in a new build. i have noticed mine is rubbish with only getting the same litres per minute. is there any other restrictors put into place that causes such rubbish flow? i have a 32kw boiler vailant. is there a reason why these new builds get such crap flow rate?
Good vid but the reliability of those pumps is questionable
Time will tell I guess
That is not your problem. Straight back to the house builder.
Oh mate trust me we have tried….. but when they don’t answer the phone or get back to you what can you do.
My son and grandson couldn’t even use the shower as you saw!!!!
I will be following it up and now have great proof with this video…
I have fitted many of them dint last for long max 1-2 years
👍🏼👍🏼
New house, shouldn’t the house builder plumbers be requested to come back ?!?!
If only it was that easy….. the developers are not even returning calls
If they couldn’t get it right first time would you want them back. To be fair it’s probably not the plumbers fault , just crap developers.
Slightly off topic, a developer has been building new houses opposite where I work, on top one of the houses straight opposite, a roof tile has moved, said developer has been phoned/contacted on numerous occasions and no one had been to sort it and they’re still building houses there
On a new build? Says it all about this country . . .
Yep
Water companies have to provide (to the water responsibly boundary) for a single domestic building 1bar whilst running a flow of 9lpm. When on a shared supply these go up…e.g 1bar with 18lpm flow for 2 props.
Some areas are just low pressure because they may be high up a hill however water companies are now fitting PRV(like the domestic one but a lot bigger and more sophisticated) on large water mains outside to pressure manage entire water networks. They are well within rights to do so as it’s all regulated by ofwat…just annoying for everyone else to adapt their plumbing to suit.
Shocking isn’t it…. Wasn’t even 4litres per minute upstairs
Great bit of kit that, I would be handing a bill to the developer, there is no way that was acceptable, especially with a combi fitted on it.
I’d be inclined to drop some flyers around the estate, offering everyone a price on installing them, you’ll clean up😀
Yep I will be speaking to them very soon
What about the neighbours pressure/ estate? Isn't the property under warranty?
Yer… but the development company are a nightmare at the moment… I’m following it up
@@MJTiffPlumbing Could imagine either way nice job
Will it not suck to water from the adjoining properties 😂 And that crap push fit waste pipe takes up half the bloody cupboard !!
It just pressurises the incoming main to that property 👌🏼
I would have put you at 40 years old and you have a 27 year old son? Whats your skincare routine mate, never mind about the plumbing 😂
I will take that buddy…..🤣👌🏼👌🏼
I have 3 grand kids aswell….😉
Interesting , are there flow restrictor’s on the taps ?
Greetings from Australia, I’m sure you have , normally I’d check from outside , see what pressure is like outside coming in at the main or at the water meter outside .
Does yr local utility guarantee a certain mains pressure ?
Why is it so under pressure / flow in the first place ?
BTW 33 degrees c , is winter in Australia …😂.
Thanks for the comment mate….
No flow restrictions or anything, just really bad water pressure!!!
@@MJTiffPlumbing interesting thanks. “ Sydney Water”, here in oz, guarantees us 500 KPA as a minimum to a domestic household about 75 psi … used to be much higher actually. The pump system is great I’ll research them here .
Immigrants wouldn't, put up with that.
I bet the housing association places have better flow rates.
Apparently by 2025 we are doing away with Gas and also reintroducing Wells
🤣🤣🤣
Great video- Mark, What's the purpose of Pressure Reducing Valve being there- Thanks' in advance.
I had that on one of my new builds the problem was the waterboards contractors got ballast in the open ends took ages to clear the main
👍🏼👍🏼
How they specified a combination boiler.with 9 l/min when the c24 ( which is the smallest logic ) is 9.9 l/min @35degree celsius rise I don't know.but hay ho !
I remember I fitted one of those salamander tap boost pumps about 7 years ago in a 10th floor flat .I had never fitted one before and was sceptical.but I did everything it said it would.and as far as I know still working today.
Water companies I think are committed to providing a minimum of 0.7 bar .or aim to provide 1.0 bar of at the end of there communication pipes.
Fantastic video as normal.
Thanks mate….. yep so many red flags on this is unreal..
At least the Home Boost worked👍🏼👌🏼
Thank you for the excellent feedback!
What a shame for the builders who leave the building unusable. They should fix it under warranty. The second thing is, why install the PRV before of the booster pump? How was the pressure with the mains without PRV? What point is to fit PRV when mains pressure is low? Hm
What happens when they do fix the mains pressure and it’s sky high…… that’s why you have a PRV inline
I just don’t understand, why you didn’t replace the T-joint going into the rest of the house, behind the sink. You could feed the rest of the house directly after the booster. Now you first get a few turns and several 90 turns, before you go into the house. Also the 2 90 turn of the old spot of the PRV look a little it’s made by an amateur. Just take a few more minutes to look for improvements of your plan, I’m sure you’ll see them too.
Feel sorry for your son Mark ‘cos everybody has to live somewhere, but the developers couldn’t care less so long as they’re selling houses. Wouldn’t have a new build as a gift. Good job your son has a brilliant dad. Keep up the good work Mark
Thanks mate…..🙏🏼🙏🏼
It’s so bad isn’t it….
Our shower is up and down because the pressure is just too low. this looks like a fix!
👍🏼👍🏼
need to buy that water cup tester,get proper messurement of flow,then can make a decision,how to fix it,go back to collage stuff,draw water main on a peice of paper,size of pipe,then were it goes,what it got to feed,drain on the pipe,size the pipe to supply the load required ,sounds a lot ,but easy to do ,not take long ,takes me back to my city guilds days ,level 1 ,2,3 ,learn stuff that i thought i never needed,i like to solder pipe,but being in the real world of plumbing ,people houses,need to know circuit design,load,then can fix any think,like the romans sent water miles,to towns ,and sewage,and the canal system of the victorians ,went every were,a lot of water,and had to be flat too,old school knowledge,my house had lead pipe ,3/4 inch and feed house,sheds,garage,pond,out side taps,was fun working out pipe sizes to make it work,you can down load a pdf of city guilds water pipe regs ,size and length ,for volume moved,that water cup is a very powerfull tool,gives you data,at source,running water and static water
You could not have a shower in that house with such low pressure ! should not evan passed the snagging list before someone moved in, shocking ! send them the bill for the install. i looked up the legal water pressure, Under the Water Supply and Sewerage Service (Customer Service Standards) Regulations 1989 there is a minimum pressure of 0.7 bar that needs to be maintained in communication pipes serving premises.
Shocking isn’t it
Never even knew you could boost a main..thanks
Now you do 👍🏼👍🏼
There is a common misconception that you cannot boost a home’s mains water supply. However, this is not the case. The Water Supply and Fittings Regulations state that you can boost mains water if the pumped mains water does not exceed 12 l/min.
Hi mark great video. I’ve actually had one of these waiting to be fitted for a while after a new water main didn’t really help our flow rate. What’s the shower like when there’s also a tap on downstairs? Thanks
Exactly the same mate…. They are brilliant
Never buy a new house there shit .
Moral of the story 🤣👍🏼
Why put the reduction valve back??
If ever the pressure gets turned up or goes up there’s a safety valve in place
Just started watching but have water board and building company checked the main up to the boundary box and then into the main stop valve for any kinks, blockages etc. That's just about scraping the minimum acceptable, not what you'd expect from a new build.
They are not helping or doing anything…. Hence me having to sort it buddy
@@MJTiffPlumbingthat's disgusting given the profit the developers make on these new builds. Feel sorry for your lad, hes lucky he's got you to sort it out.
What causes water pressure on house to go high and than low not conderable amounts hardly notable but can see stream slows a bit. It's on a combi system. Cold water and hot water same thing.Even garden tap.
Can depend on so many things like times of the day when people are using it etc
@@MJTiffPlumbing Figured it out what it was that was causing water to go fast and slow. Inlet valve was faulty on toliet kept opening and closing randomly even when the float was at the top. Changed all ok.
Wonder how much rubbish is left under that bath ?
Probably full of crap as usual. 🙄
Hahaha yep I wonder
There has to be something wrong with water coming into the house from the street I feel it’s their fault and that needs rectifying as incoming should be around 3 to 4bar typical.
Exactly mate….. but trying to get them to sort it has been a nightmare
And we are paying for that service, not good at all.
Great video mate, invest in the Milwaukee M18 Fan, best £85 you will ever spend. We use ours all the time.
I bought one the day I filmed this… went for the M12…. It’s perfect👌🏼👌🏼
Great vid, But a random question why do you have a tent box on your van?
Thanks mate….
“Why do you have a tent box on your van”………
To go away camping with….. why else would you have one🤣🤣😝
@@MJTiffPlumbing You must do a lot of camping! When is the press fitting price video coming out?
Hi mark is this oil heating or gas my pressure is awful in my house 😢
Doesn’t mate, as long as your running a combi this system will work👌🏼
@@MJTiffPlumbing I don’t know what that means lol I got new boiler last year any recommendations for oil heating to boost water pressure
Great fix mark with the pump..👍fitted a few myself ...but a new build with very poor pressure from a new plastic incoming main supply..🤔 is not acceptable 😡😡keep up the great work...👍
Thanks buddy….. worked a treat
Thanks for positive feedback. Hope you will continue to work with our pumps 👌🏼
We all get 3bar most places in the uk.
We didn’t here
H mark it’s a bad job having to fit one of these in a new house but I was impressed with that pump seen them advertised but never had the need to fit one 👍
They are very good products when you need to use them
@@MJTiffPlumbing Mark, thank you for your trust and appreciation of our pumps.
Ive got to ask,as sure someone else will.I know you can make a vid of this ,but why have you gone to the expence when its a new build?I'd be dancing on the developer over how it passed the snagging and deemed the shower not fit for purpose.
If only the developer would return a call or even get back to me….
When your son and grandson can’t have a shower in there own home you get it sorted ASAP….. then go for the developer armed with a video all about it on TH-cam 👍🏼👍🏼
New builds. Some sucker has to buy them I suppose, despite all the online warnings. Pumps will do FA if there isn't a decent volume available to boost. It's not just about "pressure", as they will be directly related on a poor distribution system.
Needs 3/4litres a minute to work….. then it works perfectly fine👌🏼👍🏼👍🏼
@@MJTiffPlumbing Cavitation is your enemy. Let's see if those pump internals are robust over the next year.
Just need to note that HomeBoost works on flow rather than pressure. HomeBoost requires 3L/min to pass through the pump naturally to activate.
Great vid Mark! How do you like the press fit? I'm renovating my place and trying to pick between copper press fit or pex from Zurn. Would you recommend one over the other? Cheers
Yer the press is getting there….👍🏼👍🏼
It comes to something when the pressure’s so low they don’t even have to bother nipping up the olives. Is that one of the new estates in Warwick?
Yep new estate on Europa way…
Not a salamander they are crap pumps its your son why not the Stuart turner mains pump its twice the price but world's apart
Never had an issue with Salamander pumps in over 15years of fitting them…
@@MJTiffPlumbingin the south your be lucky to get a year out off 1 maybe it's our hard water.
Put some rubber under your support pipe
👍🏼👍🏼
Terrible pressure for a new build the pump should have been fitted from the start hope you had a good fathers day present for your work ha ha
So so bad…. And the developers didn’t want to know
yfoods not available in the States sadness
Oh really….. that’s a shame as they are great
nice place to bring the waste bang in the middle of cuboard lmao
Oh don’t get me started on that aswell….. unreal ain’t it🤣🫣
Impressive bit of kit that is, new builds are shocking for snagging 🤷♂️
It’s brilliant, I’ve fitted a few and all given great results
Nice. I have heard mixed reviews with these pumps. I have never fitted one. But what I have seen of them I definitely will 👍👍
I’ve fitted a few and they are superb to be honest….. as you can see with the results👍🏼
Cracking bit of kit that, totally unobtrusive as well.
They are brilliant buddy
Excuse me, but why refit the PRV when the pressure is poor?
What happens when they do sort the main out and it’s upped to 6bar…..😉….. that’s why the PRV is still there buddy
By that assumption, we should be fitting PRVs in every single house in the UK.
Unless there are actual plans to boost the site?
What the hell did the house builder say
Nothing…. They won’t reply
What is the name of that flow meter you are using? I can't find any sort of non digital flow meter like that.
Use long stem drain offs in press if you can get them mate I think the little ones don't quite locate, they def don't with my rems gun but it is the older model so might be okay with yours 👍🏻
Yep that’s what I use mate 👌🏼👌🏼👍🏼
Part G of the building regs limits water use and often restrict its are fitted to reduce flow.
Reduce it to the point of nothing coming out of a shower and 3/4litres a minute out a bath… this is just shockingly bad development and zero care for getting it right imho
Wow amazing results Mark well done buddy and thanks for sharing ♥️👍🏼💐😘
Thanks mate

Exactly mate
Hi mark couple of questions 1.do you not need a non return valve on the main in england and 2.why did you put the pressure reducing valve back in.cheers
Pressure reducing valve because if they do sort the issue and the valve wasn’t on it could send too much pressure in
No need for a DCV as it’s within the unit
@MJTiffPlumbing I meant on the original pipework with the dcv.i see what you mean with the prv.thanls for replying
Did you close the stopcock in inside the property and make sure the meter is not spinning as also a leak on the incoming mains supply can cause loss of pressure
9 times out of 10..stopcock choked with grit /stones etc..we used to take stopcock off and flush out alkathene....when water board connect meter outside they not too concerned about mud/ grit etc getting into alkathene...left to site plumber to sort...back in the day before prv and filters, the grit would run right through the house and trap in ballvalves in tanks and cisterns..nightmare...seen it hundreds of times.
👍🏼👍🏼
While your there post some flyers in the other doors “LOW WATER PRESSURE?”
