I recently installed new hot and cold feeds to a new downstairs cloakroom. After refilling the system the hot taps were all dribbling, spluttering and showing signs of an air lock. I attached cold mains to a hot tap and left it running for 15 minutes, while opening up each hot tap. They all...
Hi all. Ive had to replace the pump isolator valves as they were leaking. All done and working but struggling to get air out. Rads are all good but when the boiler starts and stops there is odd sounds but mainly coming from inside the HW tank, sounds like water falling so im guessing air in...
Hi, I have had this problem for a week now. The oil boiler will run for a short while and then stop. If I check the pipes around the 3 way valve they are all hot and the pump is running but all the radiators are cold. I have a bleed valve next to the water tank and I bleed that frequently and...
I have a issue which I’m assuming is an airlock in the return pipe just above the boiler. The pipes go up and over and then enter the boiler at the bottom. The boiler fires up normally but the heat doesn’t get far and the the pipes next to the boiler make like a fluffing noise. I’m not the most...

Hi
We installed a combi boiler in an upper flat by taking the pipes up (above the boiler) and into the loft, and then dropped them back down to the radiators in 3 different rooms (as opposed to the normal method of running the pipes under the floor beneath the boiler which was not possible in...
Having problems with a recurring air lock in the cold water system which is tank fed. Every couple of months it dribbles out very slowly hot water. Not full flow but just a dribble. I use a wet vac to suck the air out every couple of months but it re occurs.
Is it possible it’s due to a faulty...

All 3 toilets won't refill as there is an air lock in our system. They are fed from a water harvester in the garden. The water travels to a tank in the loft and then filters to the toilets. We've had it happen 3 times in the last 2 years. A plumber comes and attaches a hose to the sink tap...
Hi all, having issues with my underfloor heating . Flow doesn’t stay hot as return just stays cold even though boiler is operating as it should . My question is does an airlock reduce the flow rates ? I can get good flow 4+ ltr / min through the loops but still the return and hence flow stays...

Hi there.
I'm after some advice on some work that we have had done today in the house to replace a single panel radiator with a larger double panel one. The chap has been out, drained down the system, installed the new larger radiator and refilled the system. He then bled all the rads and left...

Potterton boiler downstairs.
Boiler work okay, while heating or hot water demands on as soon the demand is not there boiler will go in to lock out. When pump over run is on burner is off the boiler is bring more heat into the boiler or the air lock.

Hi there,
Last week, the hot water (mixer) tap in the bathroom on ground floor stopped running. I assumed it was due to an air lock in the pipes. We have a gravity fed system, with a cold water tank at the top of the house and a vented hot water cylinder on the ground floor. We have a...

I moved into a detached bungalow last June, and last Sept I had a problem with clanging pipes which I only heard in the early hours. This stopped in May for 4 months but returned as soon as it got colder a month ago. I've been woken by loud banging in pipes about 5 to 5.30am. A local plumber...
