    Getting a smart heating (Tado): Dynamic Valves? How important is the type of TRV?

    Hi, I'm getting a Tado smart heating system (have a gas combi boiler). I don't have TRVs currently, so I need to get a plumber to replace my old valves and get TRVs everywhere. So I might as well get good ones, and it doesn't really matter whether one costs €15 or €25. I found the Danfoss...

    Do check valves work to prevent backfeeding on mixers with unequal pressures?

    Once both feeds are open the double checks on the feeds are open. So how would the double check then prevent back feeding with unequal pressures. Seen this fix suggested a bunch of times, mainly for kitchen mixers or bath fillers as showers should have equal pressures normally. But don't get...

    Multiple differential bypass valves

    Is it ok to have more than one bypass valve on a system? Planning an UFH system (heat source supplied by air-water heat pump) with 2 manifolds, each with 6 circuits. Each manifold has its own motorized isolation valve connected to a room thermostat controller. Obviously the system needs a bypass...

    Removing two isolation valves in awkward spot (on heating pipework)

    Hi folks There's a couple of isolation valves on our radiator pipework (vented system). One started to weep a while back, but luckily stopped after a bit of tweaking. I've since learned they shouldn't be there, and so with some plumbing work coming up which will require a drain down, I'm...

    heating zone valves

    Can I run a motorised zone valve and room thermostat from a 240V supply to control a single radiator when the heating is on? Meaning the valve will be open when the room is below the temperature set on room thermostat without turning the boiler on / valve will close shutting off flow to a...

    Good reliable side-entry valves

    I am SO fed up with failing side-entry valves on toilet cisterns and water tanks. They've all been engineered down to something as flimsy as a milk carton, and they seem to last no time at all and start leaking. I'd happily pay more for a good quality one - but not twice as much for the same...

    Zone Valves

    What are the best zone valves in your opinion? I mostly fit honeywell but as prices creep up I am thinking are they any better than danfoss, drayton EPH?

    Rad valves with O-rings

    Some RAD valves come with O-rings, whereas the majority do not and I just wonder if one is better than the other or whether it makes no difference whatsoever? Reason I ask the question is that I have spent ages looking at valves and have settled on the ones in the link, but I’ve never used...

    Installing New Mixer Tap & Valves

    Hi, I'm installing a new mixer tap in my kitchen. The current setup doesn't have any isolation valves so was thinking I'd cut the pipe, install a couple of flat faced isolation valves and then screw the flexi's into that. My question is, should I be using PTFE on the threads, joining compound on...

    I’m in the uk and have a bathroom radiator with two manual valves, both of which leak slightly. i know that to turn my radiator off I need to turn clockwise, but for optimal setting, how far back should I turn them, e.g. 1/4 turn? and should I turn both the left and right valves, or just one...
