Any plumbers here?
I have an "old" cold water system with a storage tank in the loft. The overflow started dribbling a good while ago so I replaced the diaphragm in the float valve and it has been fine for a couple of years but its not shutting off fully again. Replaced the diaphragm but it made no difference I was going to replace the float valve itself but its located at the rear of the tank and the inlet pipe to valve connection is all but inaccessible.
Any suggestions why a new diaphragm hasn't cured it? |

Pressure hasn't changed, not noticeably. The arm is bent anyway, dumb set up, the valve is above the level of the overflow. I suspect I'm going to have to find some way of getting access to the rear of the tank and replace the whole valve, its at a low section of the roof, no "flooring", need to crawl into position then try to balance myself crouched down on the rafters! Recipe for disaster!

We once had a loft tank with a ball valve and there came a time when changing the rubber washer did not fix the problem entirely because the seat of the valve it sealed against deteriorated with age too. We changed the valve and all was well but we eventually opted to replace the system with a new one and a combi boiler. Given what you have said about access and maybe your health and age previously Steve it might be worth considering getting someone in to do the job for you. I find myself doing this more often as time goes by because where the mind is still willing the body often protests quite strongly - and for quite a while after when I get it wrong.

If you can see the rafters (do you really mean ceiling joists?) you have not got enough insulation!!

No, I can't see the joists but I know there's no flooring in that area. When we inherited the place from my parents there was only a small floored area in the middle of the loft but I increased the size for more storage space. |
