Really weird one. It started in the summer when the outside cold tap was being run simultaneously with the hot water tap, a really loud noise followed by vibration of the pipes started.

It’s now progressed to where if the kitchen tap is, on the bathroom sink will now vibrate, make a noise when drop a little when it’s off. Now I’ve noticed when I push down the top of the tap, it helps to stop the noise a little.

The problem also happens when the bathtub hot water tap is turned on, but the sink is off.

Any ideas what is causing this, loose washer on the tap maybe or?

I’d asked a plumber to come round but he didn’t seem so sure so I’d like to try and fix it myself if I can.

A Baxi combi boiler at the property I'm renting makes a strange noise roughly once an hour. It's quite hard to describe, but it sounds a bit like it's sucking in or pumping water, followed by a sort of whooshing noise. It only lasts briefly.

I've recently received a much higher water bill than usual. I did have a faulty toilet that kept refilling itself, but that's now been repaired. I'm wondering whether the noise from the boiler could indicate a leak somewhere, or whether it's likely to be unrelated to my water usage.

Has anyone experienced anything similar? Any advice would be appreciated!

We've got a Megaflo, cold fed from 25mm blue, and then distributed around the house in 15mm barrier pipe.

It's unvented, made of stainless steel, and I believe it's at 65C. Why wouldn't it be safe to use the hot water for cooking/drinking?

I am having trouble since moving in with black mold on the toilet seat and lid in the cloakroom. It's like a dry dust and black. Nothing on walls. I clean it and it just comes back in 24hrs. I cannot see any leaks, the room is warm and dry. We had the issue in the bathroom but since ripping it out and having new installed the issue has gone. But I am still nowhere in finding the cause. Any ideas what to look for?

Hi, I have a Worcester Greenstar 27i compact boiler which has 0 bar showing for pressure. I’ve tried to figure out where/how I can let more water in but am at a loss.

The boiler doesn’t seem to have a key/anywhere to insert it like in YouTube videos, and there is a black cap seemingly preventing me from turning the valve.

There are also no blue levers/anything to twist. There is a cylinder in the loft but can’t see anything up there to let more water in either.

Any help/ideas welcome.

Edit: link to additional photos of cylinder, what looks like filling loop (but opening valves doesn’t do anything) and other random exposed pipe work in attic: https://postimg.cc/gallery/tWP1gRF
