Hi all, First off I need to say that this forum is a mine of info, the search function is top drawer. However, I've painted myself into a corner with my Halstead boiler and wanted to ask for some advice: It all started with a faulty AAV leaking water - got that changed and then the PRV let go...

Hi all, brand new to forum, was after some advice. I have the potterton performa 24 combi boiler, was working fine till 1 day ago, when central heating was put on and there was quite a loud banging from the pipes, water coming out of boiler and the pressure virtually goes off the scale? Any...

Hi all, how are you? Name's Ed, and I have a self made problem I wondered if you guys can help me with. My boiler's 3 years old, past warrenty free service etc, and normally all I ever have to do is increase the pressure a bit til 1.2 or 1.5. But tonight wasn't paying attention and got it into...

Hi Guys, My 1st post and after a bit of advice. I have an Ideal C24 Combi boiler. Got home tonight and water is coming out of the overflow. Switched off boiler and the pressure was at around 3.4 bar. The boiler has been making a kind of ticking noise the last few days (thought it was the pump...

Hi Guys can you help, I had to recently drain down my Ideal Isar HE24 boiler to fit a new drain off tap on the heating return pipe which was leaking. Refilled and everything is working fine except for the pressure guage which reads 3 bar when the heating is running, when the heating goes off it...

Hello I am currently getting my bathroom refitted. I want to replace the thermostatic mixer shower above the bath. I got one from Screwfix - Triton Tesla for a good price, but when I read the box it stated that it should not be connected to a gravity fed hot supply and a mains cold supply...

Hi, I'm wondering if anyone has any idea what is going on with my boiler. A number of strange things have been happening with it. A few nights ago I came out of the shower (water heats from boiler) and noticed the central heating had turned on. I checked the thermostat and was switched right...

Recently the pressure in our boiler dropped to zero. I re pressurised the system and removed the fill loop. checking the pressure vessel it was also at zero. I pressurised this to 1 bar, which put the system pressure up to 2 bar. dropping the system pressure back down to 1.5 all seemed ok...

Hi I have an unvented system (Santon cylinder) & noticed that the pressure when cold is over 2.5 bar. The hot water is also extremely hot. Can I reduce the pressure by bleeding the radiators? Any advice appreciated.

Hi all, I have Glowworm condensing combi boiler at a rented property. The central heating pressure in the system has always been 0.9 cold - 1.1 (max) when running. It has been like this for a few years. I then moved out and rented out the property. Being let, I had to get a gas safety cert last...

ok so im a complete noob with no clue about this and im still waiting for my landord to get back to me. Anyway, got back form the holidays and it turns out one of my housemates decided to switch the boiler off before they left, there was no pressure so i reset the system and turned the valve to...

Hi, I have a boiler that has not been used for about 6 months. The system had been drained until yesterday, when I filled it back up. I bled all the rads, no problems, no leaks. But when I try to run some hot water or turn on the heating the boiler fires up perfectly, then the pressure...

hello, Would really appreciate some advice re: system pressure being too high. Have bled all rads and pressure drops a little but then just climbs again to 3 bar. Have cleaned out the filter on the boiler also. Is there anything I could try that might get pressure back between 1 and 2...

I have just had a Megaflow installed and am about to run the secondary pipes around the house for hot and cold water. However I have heard two different versions of what size to run. The first is that you run 22mm up to a manifold then split off with 15mm to the appliances, as this will give...

I'm in the process of buying a new kitchen and the type of taps we want only seem to be suitable for a 'high pressure system'. Based on what I have read, I have a low pressure system (tank in loft, hot water tank in airing cupboad, and condensing boiler in kitchen). However, our water supply...
