Morning All
I have a Megaflo unvented cylinder . Water had been dripping into the tundish so I tried to recharge the air gap, but when I went to turn the pressure relief valve it would not turn at all, as it usually would. My shower has been dripping in the bathroom next door , could in anyway...
Hi, all. I have a leak problem behind the washing machine. It's a pipe that is leaking directly into a drain. It used to drip but now is leaking a steady stream without stopping.
Seems to be coming from water heater but I cannot tell. It is cold water. When I turn off the main water supply, it...
Hello
I checked the pressure on my boiler and it needed topping up, however after doing this there’s now been a very slow leak from what looks like the area around the valve. Any suggestions how I can fix this? As far as I am aware it wasn’t there before so can only presume my opening the valve...

We are in the process of having an extension built and our new combi boiler was installed about a month ago. The wall is now looking damp and going green, I’m worried it can only get worse, is this normal?
Thank you.

I have a Grundfos MQ series domestic pump and it has started cycling on and off. The pressure at the outlet reaches approx 2 bar of pressure and the pump shuts off. The pressure then immediately drops as it overflows out of the Pressure Relief valve. Once the pressure gets to 1.5 bar the pump...

Hi All
I have a Ferroli 701 Optima which leaks water through its CH 3 bar safety pressure relief valve. The water pressure on gauge NEVER goes above 1.2 bar though (with CH on or off). When i do put pressure in the PRV passes and it drop to zero over 10mins.
The Pressure Gauge USED to go over...
Can anyone help me with this small problem. To make a long story short basically this screw at the side of the pressure relief valve keeps leaking. I tried to undo it and tighten it again but still continues to leak drops of water.
Any suggestions?
the PRV has been replaced twice in the past few months and this seems to cure the leak temporarily, however the leak is now worse and is clearly caused by a different problem. The pressure gauge rises quickly upto 3 bars, (we release the pressure manually) but then when the heating/water is off...
Hi. Just wondering how a properly functioning pressure relief valve operates.
Does it have it's its own mechanism that detects when the pressure is above 3bar? Or does in rely on the water pressure sensor? The two don't appear to be linked in any physical way.
Also, when a correctly operating...
Calling all pro plumbers :D
I appreciate this isn't black and white, but in its most basic form could anyone give me a rough idea of how much it would cost (in terms of parts and labour) to carry out the above titled job for an oil fired boiler. Just a ball park figure would be great.
Many...

Hi all, I’m hoping for a little help with the below problem.
What I believe to be the pressure relief valve exiting out the side of my flat has a constant flow of hot water discharging from it. It is located right next to my boiler although it is boxed in. I am having trouble diagnosing (very...
Hi
We have a vaillant turbo max 824e rs combi boiler that has been serviced and we've been told that the boiler is found to be gas safe but is in need of a new expansion vessel along with a pressure relief valve.
How much should be expected to pay for this (Coventry)? I have only one quote...
Hello there, would be very grateful to get some help on my copper pipe dilemma.
With reference to the attached image, when unscrewing the valve (to be replaced with a new non-leaking one), the male pipe (on the right hand side) it is screwed on to rotates as well as if the two are stuck...
Hi,
I have an unvented system and in the cupboard where the hot water cylinder is there is a mains pressure cold water feed, this goes through a 3bar cold water control valve / 6bar PRV combo before going into the hot water cylinder (see pic 1 & 2).
The relief side of the PRV is dripping...
