I know…

Should add the valves from the cold tank seem to work fine, with the pump off flow was as expected, cold tank drain seems fine, and I didn’t run a hot tap until the cold tank was full after cleaning it. Some photos of how it’s “plumbed”:

Having ongoing problems with a lack of hot water flow from both ground and first floor taps - it’s a basic vented cylinder system, cylinder is fed from the cold water tank in an attic; all the cold taps upstairs and down off the mains, the attic cold tank appears to directly supply only the...

Have a Bosch HBC 84E 653B combination oven/microwave with a broken function selector switch (basically, it will only work on the microwave setting and no other positions on the rotary selector work). I’ve bought a replacement switch, which fits behind the fascia panel and the knob, but am not...

Limescale covering the cold entry gauze, hot with bits of (I think) wasp bodies possibly via the previously-partially uncovered CWST.

New pump fitted, some improvement (especially in noise levels), but the problem was a completely clogged shower valve. Will re-plumb the outlet side to sort the flexi angles another day.

I assume that I can just isolate the cold flow into the cylinder to stop flow out of the cylinder (assuming nobody turns a tap on)?

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?
