Attempting to replace a dual shower pump, which has been plumbed to serve one shower (cold feed from a CWST) and three mixer taps (cold feed from mains). The hot feed to the pump inlet is taken from the top of the top of the hot water cylinder via a copper tee, the other side of which is the...

Regenerative/peripheral is just the type of turbine pump in them.

Thanks - yes, one of the end cap cover screws was loose and it’s been leaking, albeit very slightly. Am I likely to cause a problem back-flushing the attached thermostatic mixer shower unit with mains pressure?

Unfortunately there aren’t any in-line filters in the pipe from either tank, and it doesn’t look like the pump has any. I’m wondering if the issue may be in the plastic pipe to the shower post-pump, as hot flow with the pump off is adequate. With the cold hoses removed, there’s no obvious...

Thanks. There‘s virtually no cold flow from the CWST with pump either on or off, which is why I thought it was either a cold-side pump blockage or possibly cold-side pump outlet to shower blockage (not sure if I can reverse-flush that pipe via the shower hose without damaging anything in the...

Having problems (possibly) with a Stuart Turner dual shower pump (old Aura model, looks like the current Showermate) - it supplies a single shower and also (I know it probably shouldn’t) the hot water to three mixer taps. The cold feed to all three taps is from the mains supply and they all...

Noted, thank you.

Thanks - might see if I can attach a length of hose to the end of it. It’s a family standard-looking rectangular plastic 50 gallon tank.

Cleaning out a cold water tank today (ugh) - the board it should be covered by was only halfway across the top because there’s a rigid copper overflow pipe above it coming from the top of the adjacent hot water cylinder. Are covers available with provision for this overflow? Should it enter...

New diaphragm washer bought, problem solved - thanks all very much.

Thanks - will try to correctly identify the manufacturer before I find I can’t buy a replacement...

Thanks, there is quite a bit of limescale in there. Access is very tight, I was wondering how you’re supposed to get a hand in there.

After looking, it seems it’s a Fluidmaster. Is this likely a failed seal in the valve?

This concealed cistern has just started to fill very slowly - really just a drizzle out of the back of the valve assembly on the right (which I think should flow onto the plastic tray underneath). Problem is that access is very tight, there’s an opening just big enough to get a hand in and the...

duplicate post

Thanks both - it is an odd size, about 9mm outside diameter, the 3/8” ones I’ve just bought are far too big...

Have a leak on a flexi-to-flexi hose join on the hot outlet from a Quooker hot water boiler - am I right in thinking that there should be a rubber or fibre washer or o-ring between the two fittings? It’s been fitted for about five years, and there was only a bit of indeterminate black...

Perfect sense - now working as intended, thanks again.

I didn’t check - will confirm and report back. Thanks!

I’ve just replaced an existing nightlatch with a Yale P89 non-automatic deadlocking one, with new lock barrel, which should deadlock from outside with a reverse turn of the key. I was expecting the deadlock to require a 360 degree anticlockwise turn to engage (ie the opposite direction to...
