    Motorised valves from China

    I have tried hard to get similar to the first class satchwqell /Sunvic SML type revolving type valves instead of the quite short lived spring return type valves. I saw an advert from the Hearken company who either make these or buy them in. The only problem they are BSP threads so adaptors are...

    Mixer taps and check valves

    Hello, I have a few mixer taps to install in bathrooms and kitchen. The kitchen tap also has a wondering spray arm capability. On researching something else, i stumbled across people saying that a check valve should be placed on the cold mains feed. How can I tell if the mixer taps/spray arm mix...

    Changing/fixing a bunch of seized imperial and metric valves

    Hi everyone, I'm new here! I've bought my first house - needs a fair bit of work doing to it, including the plumbing. I'm keen to do stuff myself rather than getting contractors in, wherever possible, not just for cost, but also because I want to learn (a useful life skill surely!) I'll...

    What Isolation valves are best

    Hello, Is it ok to use a full bore isolation valve to isolate a hot and cold feed to taps or should I use a service restricted bore. I’m thinking about using a full bore with a handle as my default as I find that most of my customers struggle to muster up a screwdriver to isolate the water when...

    How can I turn down this traditional towel radiator with tap valves?

    I have recently had this radiator fitted and currently it gets very hot. I would like to turn the radiator temperature down however I'm unsure which valve I need to turn. I am not sure which is the flow or return. Or does it not make a difference? At the moment, both valves in the picture are...

    Danfoss Lockshield valves leak after adjusting

    Heating system is 14 years old. On inspection I find that every lockshield valve is fully open. After adjusting some, I find that they weep slightly from the adjustment screw - valve type is as in attached picture, with only the adjustment screw behind the cap. Leak sealant is in the system - do...

    Toilet Water Shut Off Valves Questions

    Hi, I was thinking about replacing the 3 x original Toilet Shut Off values as shown in the photo, in a property in Florida. They are not leaking and still work. I fixed some water weld around the wall cover to make them more rigid. Does anyone know if they are one piece? Or can the hose part be...

    Overflow Bath filler and valves

    Hi, I'm really struggling to find out what part I need to use deck valves like this with a overflow bath filler. Most bath fillers seem to only have one connection. This one has 2, one for hot one for cold which looks like it could work. Anything I'm missing? thanks

    UFH Thermostatic Mixing Valves

    Are there fundamental differences in some of these TMVs?. The attached one, below, would seem to be the better type where a shuttle moves to balance the hot&cold flows, as it increases one flow it decreases the other to keep the mixed flow constant, necessary say in showers etc. I have seen...

    Are my myson power extra valves closing too quickly?

    Hi, we've been having a problem with our motorised valves. Every time the heating turns off there a number of loud bangs as if the water is hitting the valve too quickly which is then sending a shockwave through the pipes. Would this be faulty valves in that they are closing too quickly or is...

    Cold Radiator - questions regarding valves

    Hi all, I'm hoping someone here can help. The radiators in my living room aren't heating as well as the radiator in bedroom, hall and bathroom in my flat. I've checked and both seem to be free from trapped air (tried to bleed and water came straight out). Now one radiator gets a lot warmer...

    service valves or not

    Refurbishing a bathroom - cold water is mains fed, hot from combi. There is a main service valve to the whole system where the supply enters the house. Do I need to have service valves on bathroom sink, shower and bath? Normally if I have to repair/replace anything I just shut off the main valve.

    Brass "Faringdon" lockshield valves leaking

    I have just tried to balance my heating system (16 cast iron rads, 3 towel rails), all the lockshields were fully open. When I try to close them down, they all leak, from a dribble to a gush. When I say all, I tried 6 and then stopped. The system was installed 9 years ago. Despite extensive...
