pressure loss

So we took a radiator off the wall on the weekend in order to paint the wall. Turned off TRV and lockshield valve, drained the water from the radiator etc. Capped off the TRV but it appears that it still kept leaking through the cap (I guess the valve doesn't close properly, never seen that...

Hi, I have recently moved into a new build apartment block (the building was completed in 2018). I live on a fifth floor and the water pressure here is pretty bad. The block has a communal central boiler and all apartments have water pressure valves/gauges on the main cold water pipe marked as...

Hello guys! Just to start, this is not a ‘sob storey’! Yes I had an a terrible bone infection that started a couple of years ago out of nowhere and was very very aggressive. I have now recently found out it’s permanent and in a way it has helped me move forward as being stuck in status not...

Hi all. Short version: I have a combi boiler which is losing pressure. Long version: Boiler was losing pressure since around June/July. Put a bucket under the overflow and worked out that we were losing 1/2 pint per day. Boiler was serviced and fitted a new pressure relief valve on 11th...

I have a shower running off bath mixer taps (i.e. not an electric shower) and for the last few weeks it has been driving me insane... hot water has been intermittent and water pressure is terrible. Plumbers can't figure out what is causing the problem. What happens is this: when I turn on the...

Hi, The pressure in my boiler keeps dropping. I've had to repressurise once or twice a day for the past few days. Obviously this isn't right so I'm looking for advice on what the issue could be. The boiler itself is new and was only installed around 6 months ago so I don't think it is that. It...

Hi all, First time post so sorry for any issues. Just moved into a new flat in London, top floor Victorian conversion. Two bed. Came with a Ariston Microgenus 23 MFFI Combi boiler. Couple of issues we’re having & unfortunately it’s the version without fault lights. Just so you know Hot Water &...

There is a leak from behind the combustion chamber below the expansion tank which has got worse recently. It does lose pressure but always has done slightly even after replacing the pressure relief valve. The diaphragm and some of the seals were replaced a few years back. The water is dripping...

We have a Baxi condensing boiler which works OK, or did. Recently, there have been several instances where the system hasn't come on (no heat and no hot water to taps) because the boiler pressure has dropped, giving an E119 error code. Each time, I have let a bit of water in using the top-up...

Hey guys, I'm stuck with an issue regarding the level of pressure that my boiler has. I've been looking around to see how I could fix this issue, and it came down to me needing a filling loop. However, whilst being confused and frustrated for a straight hour of not knowing what I had to do, it...

Hi, the water pressure on my ideal Independent C24 boiler had dropped to about 0.5 and so we have low pressure and intermittent hot water. This happened about a year ago and I managed to fix it by following a thread on here but I have no idea how I did it and haven't been able to find a thread...

Drips about half a saucer per day - but enough to lose pressure and need topping up every couple of days. Anyone can tell me what this component is? Is it possible to 'adjust' this component i.e. stop it dripping - or it needs replacing?

Have been experiencing loss of pressure on Vokera Linea boiler. Over course of week pressure drops from just over 1 to near 0. Expansion vessel and PRV has been replaced, engineers haven't found any leaks in boiler itself. Engineers came to try and track leak down in pipework including lifting...

Hello, I was hoping you could help me identify what is causing the problem with my Viessman Combi Boiler. It is a Viessman VITODENS 111-W. Type B1LA. Gas condensing and storage Combi Boiler. The Pressure drops to below 1 bar (Pre determined cut off point) and the boiler refuses to turn on. So i...

Hi everyone. I'm hoping someone can help please. Recently a pipe came off one of our radiators (long story!), water everywhere - but not all the water in the system came out. Pipe fixed, no more leak. Had to top boiler up a couple of time, understandable. However, we have kept experiencing...

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...

Having recently spent hours looking for a tiny leak in our Combi based pressurised central heating system, I thought I would pass on this tip for anyone else experiencing pressure losses. For less than £6 on eBay you can buy a moisture (damp) meter which can be pushed into carpets around pipes...
