    Hi, I am not a plumber but want some help finding at what torque at which the PRV's bell housing screwed to the valve body. can the plastic bell housing pop off the main valve body due to pressure or unscrew itself due to prolonged water hammer effect? PRV: Wilkins Zurn NR30 40mm 500kpa

    Best valve/tap type to limit water supply to reservoir

    We just had a waterhole bored and were lucky enough to find a flowing artesian, which delivers just over 500 gallons an hour without needing a pump. We need to feed only about a litre a minute into our reservoir, as this is sufficient for our rural household needs. I installed a Speedfit...

    Where can I buy this exact isolation/service valve?

    The isolation valve connected directly to our toilet fill valve has started to leak (I assume the washer has deteriorated). I'd like to get a like-for-like replacement so that I can just do a straight swap of the entire isolation valve without having to worry about resizing pipes, but my google...

    Straight valve to turn shower on & off (you'd think this would exist)

    Hi - recognise this a bit of an odd one. We have an old failed mixer valve which we need to replace. This valve actually predates a temperature controlled boiler, so the mixing functionality is irrelevant, since the cold water pipe is isolated/off. I'd ideally like to replace the shower valve...

    Thermostatic rad valve

    I'm in Canada, where the standard is NPT. I just put in a heat pump and shut off the hand valves but I want the rads in the room to warm up if the heat pump can't keep up. NPT thermostatic rad valves are available but are hellish expensive. The sizes I have are 3/4" and 1". The system used to be...

    Good morning! I have a dripping tundish, so decided it's time to replenish the air gap in my Megaflo - something I've done from time to time in the past. So I've turned off the water, opened a hot tap, and then tried to open the pressure relief valve on the Megaflo. But it's stuck: the plastic...

    Weak flush - pneumatic button mech or flush valve?

    I have a wall hung pan with a concealed cistern. The flush is the "old style" Grohe Eau2 dual flush pneumatic button. When pressed the flush valve lifts lightly and closes giving a very short weak flush. You can manually lift the flush valve in the cistern and it moves freely, flushes fine and...

    Hi, first time plumber and poster here. I've installed two new zone valves and replicated the direction inwhich the original valves were installed. I'm really confused now as I think the originals may have been installed the wrong way round. The Grundfos pumps' arrow is pointing down whereas my...
