Leaking hot tap

missile

Hi,

I have a leak from the red pressure control valve on my Quooker hot tap, see photo >

It appears that when the valve releases pressure the corrugated pipe overflows. I don't know how frequently this happens, but it appears to have been leaking for quite some time as there is extensive water damage to my kitchen unit. I have checked that the black corrugated pipe is not blocked.

Please note; the unit was not leaking prior to the Quooker engineer servicing the unit in June last year.

I await a response from Quooker, meanwhile I would appreciate any ideas / suggestions you may have?

Is it leaking from the bottom of corrugated hose connection or top of hose where hose screws onto valve?

From the top where it joins to the valve. It may not be clear from the photo, but the hose does not seal to the valve. It is designed to be open - like a sink overflow.

See below from site q&a

It is normal for the inlet combination valve to release drips of water while the tank is heating water. This is expansion water released from the tank to regulate the pressure inside the tank.

If the Quooker has been fitted recently and the valve is releasing a continuous flow or spurts of water, please check the incoming water pressure. The ideal incoming water pressure for the Quooker is 2-3 bar. If the pressure is too high, the valve will release more water in order to keep the pressure inside the tank at a safe level. A pressure reducing valve can be fitted to reduce the pressure to 2-3 bar.

If the Quooker has been fitted for a while and the valve has recently started running continuously (rather than dripping), some debris or scale may be caught inside the valve. Please try flushing the valve through as follows:

Switch off the tank by pressing the Q-shaped button on top. Run the boiling tap for a few minutes until the water runs cold. Place a container under the valve and turn the large red cap (10 bar valve) or large grey cap (8 bar valve) anti-clockwise until you hear a click. Water will be released from the valve in a quick gush. Repeat this several times before switching the Quooker back on.

If this does not resolve the issue, please contact our service department via!service@quooker.co.uk or 0207 9233355 (select option 2 for Service). Please have your Quooker's serial number ready – it is located at the side of the tank near the top.

Thanks for the link. I had looked at the Quooker web page, but did not see that info. I shall flush the valve through & fingers crossed that solves the issue.

Well I have tried that and hope it works.

There is no mention of this valve and possibility of it leaking in the user instructions.

I only became aware of the problem, when I noticed a smell of damp. I am quite annoyed at the consequential damage caused to my kitchen unit.

FYI, this is the response from Quooker:

I have had a look at the picture of our valve , the only time this will discharge water is when the tank is heating (this would be a drip or trickle and the black hose would cope with it)!or if the incoming pressure rises or spikes . we tested the pressure when onsite and it was 3 bar. the only thing we can do to prevent this happening is install a pressure reducing valve to protect the quooker valve.!!
It could also be that there is a blockage in the main waste and it is backing up out of the quooker tundish . again this is not a quooker issue , its a waste issue . with this type of situation we could install a non return valve on the black hose to stop it coming out of there , however if there is a blockage in the main waste this wont cure it so you would still need to get the waste cleared . the engineer can advise on the day .!
i understand you have had a couple of issues with the quooker in the past so im happy to provide the engineer FOC as a gesture and hopefully we can help to stop this happening .

I am rather disappointed.
Quooker accept no responsibility for the leak and consequential damage.
This appears to be a common fault as evidenced by their own web site FAQ.
I have suggested to Quooker that users should be advised this valve can leak and should be regularly monitored for leakage.
