pressure

Hi all. I have an issue with the above boiler upon firing up. The unit gurgles and only stays on for 5 minutes then flashes up with Air Pressure Switch failure. It does this 3 times before Locking out. I can resolve this by draining the Condensation trap for some reason which is External to...

Hi all, this question has come up before but unfortunately I couldn't solve my issue from reading it! My pressure is down and I don't know how to repressurise. The manual helpfully simply tells you to do it. All YouTube videos refer to the filling loop which as far as I can see I don't have as...

Hi all! I live in a flat on the first floor of a converted house. About six months ago i had a combi boiler installed to replace an old failing boiler. Recently the boiler will occasionally fail to fire up to due to the pressure dropping to 0.. This normally happens if I am away for a night or...

Six months ago we had the open vented central heating system (powered by back boiler) in our 3-bedroom semi renewed. We had a Vaillant ecotec plus 831 combi boiler put in the kitchen, and this works very well apart from the pressure issue described here. At the same time all the radiators were...

Hi, I'm wondering if anyone can help, I used to have to re-pressurise our boiler every few months which was fine, last year when we had the pump replaced the plumber changed a couple of other bits around as well and I forgot to ask about the pressurising procedure. Attached are some photos of...

I noticed water coming out of a light socket on floor below where water tank and expansion vessels are. Looking in the cupboard it was obvious to see the silver flexi hose that connects one of two expansion vessels was leaking and judging by the amount of water on the floor it had for a day or...

Hello, We are in a 3 floor new build property. The top floor bathroom has an electric shower which is always at pretty low pressure, and drops below the cut out level when any otherp tap in the house is open, making the shower unusable. I was wondering if it is possible to fit a booster...

Hi everyone, I had my bathroom suite replaced over the summer, including a new bath, shower, pump etc etc. Since the work had been completed I had noticed that the pressure in my Remeha Aventa condensing boiler seems to go from very low (less than 0.5 bar) to very high (~2.5 bar) quite...
