pressure

Hello, I have a Worcester Greenstar 25Si Combi MK IV boiler. Neither this model's manual nor all the Youtube tutorials on how to increase a boiler's pressure seem to correspond to what this boiler actually looks like: there is no slot for a filling link key, there is no keyless filling link blue...

Hi folks, Im having problems topping up my boiler. I have read some of the other posts on the forum and thought I found the loop on the boiler but pressure wont shift. Here are the pipes, I am actually in italy. Not sure if that is the issue and pipes are set up different. But definitely cant...

Can anyone recommend a pressure limiter to use with a water softener? The instructions say if the pressure is above 5 bar, limit it to 3.5 bar. I've told the plumber several times but he hasn't done it so I plan to buy it and give it to him to fit the next time he visits. Thanks

So I just had the heating system drained by a plumber to replace a UFH mixer valve, he filled it back up and left in a hurry. I ran the heating to see if it worked OK and noticed all the radiators upstairs were only half full. I turned the heating off and bled them. I tried running the heating...

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...

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...

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...

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...

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...

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...

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...

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...

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...

Hi, The pressure on my boiler is low and has error E118. I don’t see any filling loop under the boiler but there’s is one near the unvented indirect cylinder. Does anybody now how I guy about adding pressure? thanks .

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. I did a lot of research before I finally bought a washer and this is the first I've heard of this. Is it something...

Hi All I have just moved into a new house in deepest west Wales. It is a recently converted old farm house. It is a modest sized house with about a dozen radiators. The plumbing is relatively quite new (about 10 years). In the corner of our utility room the is an absolutely huge pressure vessel...

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...

Hi, just looking for some advice before I get a plumber in to investigate this for us. we moved in to a detached house 3 years ago, house is about 20 years old with a gravity fed system. Boiler was replaced about 6 years ago. During recent kitchen refit, fitters suggested our water pressure was...

Hi, We need to presurise our Vaillant Ecotec 24, but for some reason there doesn't seem to be a handle on the valve? Any tips on how we can presurise? I've posted a picture for reference.

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...
