The only problem I found with the video is that you advise to open the temperature and pressure valve anticlockwise to the right. Anticlockwise is to the left!!! Does it make a difference. What if I have no tun dish?
When fitted to ground floor or in an apartment without a 'down stairs' this method doesn't work consistently. Shouldn't the advise be to drain from the bottom stop-cock drain on the tank either into the shower tray via a hose, or have it plumbed into drainage that the bath and sink drains into?
Thanks . Great video . Could I know the normal range of pressure (bar) of the cylinder ? Do I need to maintain a suitable range of pressure after discharge ?
My megaflo tank leaked through the immersion heater. I called out a plumber and he replaced the immersion heater and serviced the tank. He said this had happened beecause the air pocket had disappeared. My question is, why wasn't the excess pressure released through the safety valve and out through the tun dish? This is a bit worrying.
Great video. I have one of these tanks but started to make noise whenever I use the hot water? what do I need to do? change the ballcock valve (if it has one) or is to do with pressure
Hello. I like your videos. They easy to understand. Thank you. I have subscribed to your channel. I have a megaflo water tank. I tried to open the drain cock. The water that is coming out is black. Is that normal from the tank or is that coming from the radiators as the water in there is also black. Thank you
Great BUT.... Why does the bubble deplete in the first place. Mine needs doing pretty well every month. I've never got a satisfactory explanation from Baxi when I've asked. They give variety of explanations but thet never manage to explain why air travels down through water and out through hot taps. They've cancelled any thought of air dissolving in the water but I'm not convinced it cannot happen. I'm going to fit an expansion tank and get rid of the issue for good. Megaflo is a great idea on paper but if the bubble cannot be relied upon to stay in place it's a non-starter...unless you're a plumber. Plenty of call-outs ensue and any detractors are told explanations that defy simple physics!
When I go to open the pressure release valve after doing all the steps before it doesn't open but instead clicks when I turn it. But if I just turn the pressure valve without turning off the cold water supply then it does release the pressure. What's happening here?
What about the loud clunk when you first turn off the mains.I have that same clunk when I turn off my cold water tap it does not sound right and is annnoying my neighbour.
Hi Rob. My Megaflo is on the first floor and I isolated the cold water but when I open the lowest hot water tap on the ground floor hardly any water flows out at all. When I open the pressure relief valve nothing happens at the tundish. Any suggestions please?
hi. i have a similar issue with my megaflo. hardly any water flows out of my hot tap & almost no air gets sucked in (no gurgling sound). did u manage to get yours sorted???
I'm still getting water dripping in tundish, despite replacing TPR valve and draining tank to restore air gap. Any advice? The tank is c. 16 years old. Could the internal air gap just be kaput and I need to install a separate expansion vessel? Thanks!
The strangest thing about doing this, is that immediately after turning the mains cold water back on, and water starting to come out of the lowest hot tap, it was red hot. That’s with the boiler turned off and not yet having had a chance to heat the new cold water in the tank. Any plumbers that can explain that? The hot water hasn’t been on for 4 hours.
could a clogged & dirty mesh filter / strainer in the combination valve cause the water pressure to drop at my taps & shower??? ive noticed the pressure drop for a week now & have checked all isolation valves are still fully open - so im wondering if i should now check the mesh strainer in the combination valve. i still have the old style heatrae sadia megaflo combination valve (15 years old) with 4 allen bolts!!! i think it may be time to change it for the new style of combination valve. any advice please???

Good video; it is a turn to the LEFT not right and as you say, anti-clockwise for the pressure relief on the cylinder. cheers.
What happens if no water comes through the tundish when I turn the pressure release valve? Lots ob bubbling sounds as well.
A lot bloody better explanation than the Rolf Harris impersonator.
The only problem I found with the video is that you advise to open the temperature and pressure valve anticlockwise to the right. Anticlockwise is to the left!!! Does it make a difference. What if I have no tun dish?
This was really helpful. Saved me remaining without water for couple of day

Thank you for the video. I have to repeat this every month on my Megaflo if I want to prevent water dripping into the tundris.
rotate the valve to the right? looks like yer turning it left?
Thank you for the video. I have to do mine every two weeks. I take it, this is isn’t correct?
What would cause the water pressure to drop in a mega flow system PLEASE
Simple to follow up instructions , plain language , just done mine for the first time .

"Rotate that valve to the right, anti-clockwise." You must have some very odd clocks. I think you meant LEFT. ;-)😁
Great video any idea how to fix a E119 error thanks?
Great video. I have one of these tanks but started to make noise whenever I use the hot water? what do I need to do? change the ballcock valve (if it has one) or is to do with pressure
I've done this and checked my strainer filter, which was clean as new, but I only get dhw for a few minutes. Any advice?
Wow, why doesn’t my pressure relief valve open as easily as that! This sucker tears my skin up it’s that tough
Wat about if the prv start leaking afterwards. As because of scale in hard water area prv leaks if u turn and let the water out

Is it normal that it will make a lot of noise for over 30 minutes and the tube sounds like they are full of air?
Great BUT....

You forgot to mention the plumber speak, cheeky chappy clowns.
i have cold water coming back into the cylinder, hot water goes luke warm, should i try doing this ?
Very clear instructions. Thank you so much.
Thanks, great simple professional explanation
When I go to open the pressure release valve after doing all the steps before it doesn't open but instead clicks when I turn it. But if I just turn the pressure valve without turning off the cold water supply then it does release the pressure. What's happening here?
Do I follow these exact same steps if my Megaflo connected to system boiler?
Useful video except think you say rotate to right is clockwise and then you rotate it anticlockwise
What about the loud clunk when you first turn off the mains.I have that same clunk when I turn off my cold water tap it does not sound right and is annnoying my neighbour.
Does this fix if you are not having hot water
Do I have to turn off the power before running the steps?

Great video. My tank way empty! So once blue cap was off took 3 seconds to stop! Still no hot water for me 🙄
I'm still getting water dripping in tundish, despite replacing TPR valve and draining tank to restore air gap. Any advice? The tank is c. 16 years old. Could the internal air gap just be kaput and I need to install a separate expansion vessel? Thanks!
Call the manufacturers helpline and ask them for advice. It could be any number of things.
What if it’s cold water coming from turndish?
do you know big Will Amor? big wire fan
This was great 👍. Thank you solved my issue
This can take sometimes half an hour to vent the vessel! Not just 3 minutes!
The strangest thing about doing this, is that immediately after turning the mains cold water back on, and water starting to come out of the lowest hot tap, it was red hot. That’s with the boiler turned off and not yet having had a chance to heat the new cold water in the tank. Any plumbers that can explain that? The hot water hasn’t been on for 4 hours.
You’re only draining a small amount of hot water from the cylinder.
Great, simple and clear explanation 👍
My cylinder is on the ground floor. Can i still use this method?
Yes you can.
could a clogged & dirty mesh filter / strainer in the combination valve cause the water pressure to drop at my taps & shower???
ive noticed the pressure drop for a week now & have checked all isolation valves are still fully open - so im wondering if i should now check the mesh strainer in the combination valve.
i still have the old style heatrae sadia megaflo combination valve (15 years old) with 4 allen bolts!!!
i think it may be time to change it for the new style of combination valve.
any advice please???
Thank you , very useful.
How often will I need to do this? 😐😐😐
Every 6 to 12 months.
@@FoodInDaHood better I go with an external expansion vessel!
Thank you 🙏
Thanks great video
God bless you
That simple! Hoping the same holds for our evocyl cylinder 👍🏻
Turn anti clock wise right 😂😂
