    High Pressure - Is there air trapped in the system?

    Hello I have a Worcester condensing boiler and recently changed the towel rail in the bathroom. I filled up the new towel rail and then topped up the boiler a little to return the pressure to normal. However, now when I run the boiler the pressure goes up high to 3 bar. So I bled the...

    Using a standard shower pump for the whole house

    I have a gravity fed system which consists of a cold water storage tank in the loft and a hot water tank on the ground floor in an airing cupboard. The hot water pressure on the ground floor in the kitchen and toilet is decent, which is expected as the water has a longer drop from the loft. On...

    Combi system losing pressure

    Has anyone known a Grant 26 combi (external) to leak internally into the flame chamber? For the approx four weeks, every morning the boiler has lost all it's pressure. I refill the system to 1.2 bar, and it kicks back in, and works fine - rads toasty warm and hot water is hot! This may last two...

    No central heating on BAXI DUO-TEC COMBI 24 HE

    Hello everyone, My home has a BAXI DUO-TEC COMBI 24 HE. The radiators won't heat up even though the boiler is showing a green light saying they are running. The hot water is still working though. I've tried bleeding radiators and then pressurising the boiler after but I still have the same...

    venting soil stack through a wall?

    I have a soil stack in my attic that I discovered is open. I fitted a Durgo AAV but this caused gases to build up and leak out from the bath p trap. I took the Durgo off and the smell stopped. So I'm thinking I need to vent the soil stack externally. My roof is asymmetrical, it rises to the top...

    Combi boiler with 2 showers at once - enough power?

    I am currently using a system boiler (Ideal Mexico Super 2) and water tank, which is about 30 years old. I'm looking to replace this with a Viessmann 100-W (B1KF) 32Kw combi. I was wondering would I be likely to see a significant difference if 2 showers run at once? I'd like to avoid needing to...

    Mixer tap turns on by itself

    I have a combi boiler driven heating system and a mixer tap in the shower, the one with temperature control knob. After a shower, when I turn off the tap, it doesn't go to zero position but the water stops completely at say 30/100 position (100= fully open). Then after few hours, mostly in the...

    Boiler pressure cold tap not working problem

    Hi everyone, I went to top up my Logic S15 boiler earlier as the pressure gauge was at zero. I’d done this before so I knew to expect to hear rushing water through the pipes when i turned the valve, but I heard nothing. I unscrewed the filling loop because i thought that might be the issue, but...

    Electric shower not receiving full power

    Hi, so recently my electric shower started running lukewarm at settings where it would usually run nice and hot. To get it to run hot, it has to be turned to higher settings, but with that, the water pressure drops significantly. I’ve also noticed that the half power light is no longer lit...

    Pressure washer backflow preventer?

    I just bought my first pressure washer and in reading the manual it has a dire warning about not connecting it to the regular water supply without a specialist backflow preventer.

    First time living in a house with a combi. When I run the cold tap it triggers the combi hot water setting, I've checked the pipes and they are all connected correctly. The combi is just over a metre from the cold tap, is this just the slight pressure drop triggering as the boiler is so close to...

    Increasing Boiler Pressure

    Hi, Our boiler pressure is currently reading at 0. The heating is still working (not too sure how or why!), but I think we need to increase the pressure as some radiators are not bleeding (no air or water coming out). I’m trying to work out where I need to put the filling tube but I’m not...
