pressure

We have a leak and ripped up the floor.. Found a bit of pipe that looks like this (image attached) The boiler was loosing pressure quickly about 0.5 bar of pressure every 15 mins. Since this bit of pipe was fixed the pressure is holding for longer but still dropping, much slower (about 0.5...

My cold is mains fed and I'm looking to install a single impeller on hw (tank fed). I've already raised the tank to ensure I have the minium ltr/min feed but what I'm wondering is, if at the bath/shower I start mixing the cold and hot then isn't that going to affect the hw ltr/min feed and...

My closed central heating system has been fine for years. 6yr old Baxi combi boiler, 11 radiators. One bedroom radiator was discovered to be full of air (more air than water I reckon), so I vented it. In doing so the system pressure dropped, as you'd expect, and the air stopped coming out, so I...

My hot water stopped working and I noticed the pressure on my VAILLANT TURBOMAX boiler had dropped to zero. I increased the pressure to 1.5 by opening the Filling Loop valve, but after I closed the valve, the pressure kept on rising getting very close to the red area. I bled a radiator and it...

Hello, I’m hoping someone can help me. We’ve just had an Aqualisa Quartz shower installed and we’re having nothing but problems with it. When you first get in, it’s amazing, however it only gives out 7 minutes of hot water before it turns freezing cold. You can then turn it off for just 5...

I have a water tank and boiler linked to 3 showers. When turning on the shower the pressure is great for roughly 10 seconds then it slows down, it's not terrible but I'd like to keep that initial pressure if possible? Is this set somewhere on the system or perhaps just a limitation?

Hi Can some one help loads of boiler issues over the last two weeks with no pressure and leaks. This is now fixed just waiting on another part. Should it be like this as the black gadget on the pipes was not there before and there is a constant drip with in it. The electric is constantly on and...

Hi, I bought a used troc tdi 2019 from a main dealer three weeks ago - 19 inch alloys. On the long motorway drive home, tyre pressure light came on. Checked and it was 12 psi and reinflated. Took the car to a tyre shop, no leak found. Resealed and new valve. Couple of days later, again tyre...

Hi. I have a baxi 105he boiler. Pressure is around 0.4 bar so very low. When heating runs it goes up to around 3 bar. If I run the hot water at the same time the pressure goes up to around 3.3 bar and water comes out the pressure overflow pipe. What would cause this? Thanks

We're having issues with the pressure on our Potterton Performa 24 boiler, it currently stands at zero. When the water is turned on it goes up to 0.2 absolute max. We're having issues getting hot water in our bathroom because of this. I'm attaching a picture of our pipes - I've marked the two...

Hello I have no pressure in my boiler and know I need to open the valves of the filling loop to pressurise the system but I have no valves on it and it’s not an easy unscrew system either. Turning the valves to the top of the copper pipes does nothing either

Hi all Noticed the condenser pipe had come out of the bottom of our boiler a couple of days ago so switched the boiler off for a day and then realised it was an easy fix so pushed the pipe back into place. When I put the boiler back on again I noticed the pressure was low so opened the valves...

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...
