airlock

Hi, Can anyone advise as to why the cold water to my bathroom keeps airlocking? This originally happened about 12 months ago and has happened 3-4 times since. It’s an upstairs bathroom, fed from a tank in the attic. The tank is about 8 Meters away and feeds a bath, sink and toilet. The tank...

Hello, today I woke up to no cold water coming out of my bathroom tap or the toilet so I can not flush the toilet, hot water works fine. I’m not sure if the cold water works in the shower as the shower seems to only give warm water and it being stuck on that temperature. the bathroom supply is...

So I’ve had a rad in the conservatory for years which the pipework is spurred from upstairs and it’s gone cold with cold pipes too for the first time. Expecting a simple fix I bled it, made sure the valves were open but no effect. So now I suspected a stuck valve (though both were kept open...

I have a Rayburn connected to hot water cylinder indirect with radiators which turn on when at certain temperature. The system has been working for many years with no issues, but when I drain the system I get an air lock which sometime sorts itself out when the temperature gets to 90 deg. I...

Initial Plumbing set-up: Loft: Cold water tank with 1x 22mm feed to HWC, and tee-ing off this 22mm just after it leaves the tank is a 15mm HEP feed down to the Cold side of the shower pump under the bath on ground floor. (there are no other Cold feed off the tanks as all the cold taps are mains...

Hi there. Three weeks ago we had a new pump fitted in our (conventional) boiler. Now the central heating sounds like it's possessed. Whenever it comes on there's a period of about ten minutes where it sounds like the pipes are going to pull apart; clanking, clanging, whooshing, HUGE crashes and...
