    bathroom isolation valves!?!?

    I’m trying to fit new pillar basin taps upstairs. Before I even got to that part I turned off the main stopcock under the kitchen sink but of course it didn’t turn off the water upstairs (who knew!?!) So I tried the isolation valves in the bathroom and only the hot one turns and the cold won’t...

    High Flow Double Check Valves

    Hi all, I’ve a customer with a failed double check valve on a water softener, it’s 22mm compression but with a far larger bore than the usual DCV’s you see online. Anyone know if they are called something different or where I can get one? I’ve even been on the water softener website and they...

    Corner valves for a radiator

    Hi, I have bought corner valves to use on a new towel radiator. As you can see in the attached pic, one part of the valve has a small circular hole in it, and the other part has a large semicircular hole.

    Sourcing replacement manifold actuator valves

    Hi, we had underfloor heating installed about 15 years ago. Some of the actuator valves are now leaking and we need to replace them. I'm trying to source some that fit. The plastic caps which came with the originals had the 'Watts' brand on. I've tried ordering a couple of the most common valves...

    Can motorised valves go under floorboards (legally)?

    Hi guys and gals, I'm looking to try to change from a Y-plan to an S-plan-plus this year to have a heated bathroom. While the house isn't that large, a mixture of south-facing brick and north-facing (and Jerry-built) timber frame construction means no single thermostat will cut the muster...

    Isolator valves on basin taps

    Hi I have always had a poor water delivery to my bathroom and en-suit basins. The cold is just about acceptable but the hot is pathetic coming from the tank on the same floor. Both rooms have isolator valves fitted in the correct direction and then to flexi tails that just reduce the flow...

    Are there any "Recommended" Smart TRV Valves for large houses?

    Hi All, I thought I'd come to the experts and see if anyone is installing and/or recommending the use of any Smart TRV valves? Particularly in large(ish) solid wall houses. I live in a 1920's arts and crafts house - it's about 2000sqft, not massive, but it's approx 25% larger on the...

    Kitchen stop valves result and questions

    Hi everyone, Finally I have figured out what the two stop cocks in the kitchen do as they both had to be replaced due to leaks. The one under the sink stops the cold water from coming into the kitchen tap and the one which is in the wall panel is connected to the incoming mains water and needs...

    How do I fit Bosch thermostatic valves to old radiators .

    background: I have 15 radiators 20+ years old with no thermostatic valves and Bosch instructions depend on replacing the actuator part only of old thermostatic valves. Surely there is an option for new complete valve replacing? Tom

    what is it with Ideal Standard inlet valves

    The usual problem of quarter turn inlet valves not shutting off, so I eventually found replacement diaphragms 32mm... and although they fit properly, the water still does not shut off. If I lift the float up I'd have thought the water should shut off but it makes no difference. So I tried the...

    Anyone finding these 'failing' early? I'm in Ireland and have never seen these valves opening under normal conditions. Recently, in the last year, I have had three brand new PRVs opening under normal conditions. One of them was on the mains supply which actually has a pressure reducing valve on...

    Faulty Danfoss HPA2 zone valves

    Hi, Seems like both my upstairs and downstairs HPA2 zone valves are on the blink. Every other day one of them doesn't switch off at the thermostat cut off temp and I come home to the Bahamas 😅. Firstly, is it worth trying to repair them or is the fix only likely to last a short time before...
