Had my CH drained, treated and refilled 2 years ago. Once back on, the system was bled a few times, the auto air valve or whatever it is did work as expected for large pockets of air. After the first year, i bled the radiators, which i only really have to do once or twice a year, but when i...

Nice Sunday afternoon spent sorting this Yes espresso brown! Surprised at the first flush. Second more yellow / orange. Drained each ground floor rad. Flushed through with mains. Then refilled 2 or 3 times. Water ended up running as close to clear as I’m going to get it without a machine...

Rads giving coffee brown water. Had our system flushed 2 years ago, first with a strong cleaner, believe he used x800. Flushed twice. Then had 2 bottles of x100 and 1 bottle of x200 added. Think there are about 21 rads. Not thought to check in a while, as its getting cold, checked for air...

Hi I need some more space in the garage and I'm wondering if I can move the garage door forward. Currently they are fitted on the inside of the garage. Therefore no flush with the brickwork. Can I move them forward to be flush with the brickwork and therefore inside the aperture? Moving...

Ah I see No I don't have one fitted at the moment. I assume you would fit a simple gate valve on the flow to close down and slow the flow through the coil to stop it whizzing around too quickly? Yes both pump valves fully open

I've narrowed down the pump noises I'm experiencing to being exclusively related to heating the hot water tank. I used have an overlap of heating hot water and central heating but I've since separated the timings and it seems better this way but I noticed it's the hot water is the cause of...

Should add cavitation, fizzing through the pump seems worse when just doing hot water cyclinder.

Still trying to tackle issues of - running water noises through the boiler - trickling noises through the boiler - gurgling sounds usually when turning on - pump making fizzing noises - potentially cavitating in the pump The pump has been tried on 1 and 2 with no difference apart...

Would epoxy putty be suitable for this tiny leak? I only get a few beads of water but I was thinking of cleaning up the pipe and applying some of this putty. Sound ok? It's a mains feed to dhw cyclinder. Thanks

Thank you At pump fixed speed 2 the boiler does seem happier. It will happily run for 30 mins without cycling and virtually no kettling. The downside is plenty of crackling / gritty sounds and surging through the pump originally what i wanted to tackle. I may go ahead and fit a...
