Hi,
We've got a problem of fluctuating hot water from our bath mixer where the water is hot and then a minute or so later will go cold and then few mins later will go hot for a bit and then cold again. No other taps in the house have this issue.
I took the mixer apart and checked the cartridge and it was all clean. The bathroom is less than a year old so wasn't expecting it to be that.
We had a plumber come out today to look at it. While he was running his tests on the boiler he had the central heating on and when we then checked the bath it was fine, no fluctuating hot water so he assumed he had fixed it (even though he couldn't really explain how).
Checked it again this evening and the problem returned. So I turned the CH on as a test and the problem didn't happen, hot water from the bath is constant.
Can anyone advise why it would be fine when the CH is on but if only the DHW is on then it fluctuates?
Thanks!
