Why do my radioators turn on when the hot water tap is turned on? We've turned the dial on the boiler to "water only" but it hasn't worked. We have an ideal combi boiler. Is this something we could fix ourselves or would we have to get a plumber in? If so, how much would this cost? Thanks. Much appreciated for any advise.

Has anyone knowledge or experience of a Mains Low pH water supply in Moray Scotland. I appear to have corrosion on my mainly hot water ( not heating ) copper pipes. The house has only been supplied by mains. Any help would be appreciated.

Hi, My vertical soil stack pipe that carries the toilet waste from the upper levels of my house to the underground drainage system is seeping water from all the joints. All the seals look corroded and need replacing. Also the joint at the ground floor window level is slowly being pushed apart. Its pushing outwards. There is no bracket fixing it to the wall. The pipe is not solid in the ground, it moves. Could the joint that is pulling apart just be fixed by fixing a bracket to the wall and/or should the pipe be moving in the ground and if not how does that get fixed? I have been told that I should ask a plumber. Would be grateful for any advice. Thanks.

I just wonder when we change interior stop tap in property, shall we inform to water supply because we are using mains stop outside the road to stop water supply to house or is it Ok to carried out work without informing water supply authority? And also how do we find out if the mains stop valve supply water to only your property or your neighbours too?

Question for any proper plumbers. Daughters loft tank overflow occasionally runs. I have replaced the ball valve & set it well below the overflow. However we notice that every so often it still overflows. I noticed it when i ran hot & cold in kitchen to clean a couple of rollers & today it happened when she ran a bath. Any ideas? Some sort of back flow? Its not all the time. TIA for any ideas / answers.

If an outside tap is already fitted with a double check valve in it then will it require any additional valves for the pipework inside for safety/prevent freezing?

I want to connect my hot and cold outdoor taps to one hose for washing the car etc . As they dont have an inbuilt non return valve cani just use a hoselock type non return valve on both taps , then connect to hose via a splitter/ y branch without any further plumbing. Also are they required on both taps, or should I have to replace both taps with built in valves?

Ground-floor flat - bottom-filling cistern has suddenly stopped filling - airlock?

Can mould spread throughout a home even if there isn’t a water leakage issue? Mould is still spreading in different rooms of the house. It all started with a big leak several years ago but that issue was fixed and I don’t see any other signs of leakage. So is it possible that some of the mould simply survived the initial effort to kill it off and has spread from there even without a renewed problem with water leaking? I know that moisture can cause the problem too. How can I tell if moisture/humidity levels are too high in my home? And how can I rule out the possibility that a new water leak is helping the mould to spread again?

Constantly leaking overflow from previous questions asked by others I understand it might be a ball valve not working correctly in water tank can you estimate a cost and time it may poss take to fix
