Nice pipework! (But please turn the music down or off when you're talking, can't hear a word 😅)

1600L flow might be a little high, Heat Geeks say around 1200L is ideal to reduce pump load and pipe wear.

Can you run this 100e thermostat without internet? Is it able to communicate directly with the boiler or do you have to have internet connectivity? Thanks

Hi mate nice work. Can you please advise how many kw combi boiler I can use for underfloor heating on 3 bedrooms house 2 levels Just under floor heating, thanks for your time!

Here in the UK, I inherited one, exactly the same model, from previous owner who bought it in mid 2022. It gave me error code E012, called Navien technical support, was told to seek external help by a very rude technical support guy. Spent 2 weeks plus via referrals and service companies contacting 10+ engineers, but All refused to take up the job, reason being Navien got very bad technical support, rude staff, and very difficult to obtain replacement parts - a nightmare. It seems it's far better for me to replace it with a common brand boiler like Worcester Bosch of which much easier to get engineer to fix and easier to obtain parts here. 😢😢

I have a similar job to be done in my new home. Please can you message me back if you are interested to discuss. Thank yiu, Simon.

I only install Viesmann boilers. Never had a problem with them

Aye aye mate! I have found if you use a streak / spigot elbow in wall you can cut it right down to a Max of 15mm and then you can just use the couplin version of that elbow you have and can install it second fix, you can get away with the shroud that come with the trap as everything is in wall, wished I could post a photo of what I mean 🤣 if that makes sense.

HI, Could you use Pex barrier pipe going to manifold or copper is the way? iam using Pex pipe on manifold and attached to copper pipe on boiler.

The thumbs up at the end is what MMplumber does (I’m sure it’s a compliment)

Is the expansion tank, plastic???

Search chrome basin trap pipe adapter

Off subject mate but with the mlcp. How do you size it in relation to copper pipe sizes? Do the transition fittings restrict the flow? Want to use it on a job coming up but worried about flow rates to showers etc

I think the 40mm shroud mcalpine do fits over that 32mm chrome nut

Years ago I came across where there was a neat wrap of electrical tape around the chrome part and that then glued into the fitting, I thought it was mad but I’ve used it ever since and I’ve never had a leak from it.

Finish the wall and then put the shroud on.

Instalation ruined by that dreadful dangling tied up cable.

Where do you get your mlcp pipe from? I’ve been using the pre insulated pipe … with the hard insulation and it’s a nightmare to work with

Soil runs are way to long and yes floplast is sheit

You can't be a professional plumber, in 40 years on site never hear a plumber admit to being wrong 😅😅😅

Hi i wanted to fit a new combi boiler and new radiators, will i be able to get rid of the cylinder and water tank system and run it all by the combi boiler?

Great videos. Could you possibly do a video or explain when all of a sudden my boiler isn't heating my underfloor up. All valves open, connected, boiler ok, pressurd ok. All i can put it down to is a connection issue. My heating system upstaurs is coming off the same boiler separately. Im just stuck. Thank you

Floplast must be adding a significant proportion of re-ground PVC to the feedstock compared to other manufacturers. Circa 5% regrind doesn’t alter the physical properties of the pipe much but as the amount of regrind increase so does the brittleness and resistance to UV light as well. Using the regrind from off speciation material as well as start-up and shut down helps Floplas raw material costs especially if their processes are badly controlled and produce a lot of scrap.

It's becoming more frequent now.

How are ya mate. Can’t seem to find that nerrad immersion Spanner anywhere. Where did you get it.

Just make a new seal with PTFE, it takes 30 seconds to run PTFE around where the washer would go & it is actually a better seal than the little rubber washer makes?

I blame the immigrants

The sensor, use a white pvc conduit end box, screwed over the pocket and then 20mm flex conduit across to the wall….

Thanks for the really helpful video! In 1:23 of your video, how much room did you leave between your skirting and the holes? Is there a recommended distance when installing freestanding taps?

He man. Muscles on your spit 😂

Had ot before on a sink trap, to be fair it wasn't Mcalpine, i did over come it by cutting off the old nut and warmed it gently with the gas torch until it became soft, pushed it on and left to go cold and hard again.

😂😂😂

Never 😧

I won’t make a rude comment about squeezing nut out 😂 It usually makes me just laugh and think it only happens to me when I get something like that

Deez nuts?

Superb quality craftsmanship on show rather than usual ‘it is what it is ‘ crowd.

Well done. I may need a whole day to sort out those wiring.😅

Hope your pulling them 2 top tiles down

Wishing you and yours a very Happy New Year Luke 👍

Well done 👍👌👏

Navien are pure junk, Be a future favourite with Asian landlords for sure Cheap and nasty

Better than the gym👍😀

That tool won't exist 10 years from now. To much pex. I'm still a copper and sweat guy.

WELL DONE DAD🎉❤😂

I blame the immigrants

Where the box from?

Excellent

You must be fire blanks😂😅😂😅😅😂😅

What's the score with wiring the extra pump after the plate is it just wired on the same switch live that kicks boiler and pump on

Thought it was going to be covered in blood.
