pressure

I moved into a new build around 18 months ago, and I consider myself a competent DIYer. Before I ask the builder to come and look at my plumbing I wanted to get some opinion on an odd issue we've been having. Our showers don't get hot (we've got two of them). It was most noticeable (probably...

Any advice appreciated... I have just had a complete replumb and new unvented cylinder and boiler installed. We only have 15mm inlet mains, but I seem to lose pressure and flow between the stop valve/outside tap and the upstairs bathroom. I have different flow rates and pressures throughout...

Hi in faq it says ... If you can't find one you can use a radiator bleed point, but that's in a pinch, because you'll be letting several litres of water out. Drain enough water from the system to drop the water pressure as read on the boiler gauge, to Zero. Close the drain cock. The boiler is...

Hi, so we have a potterson promax so boiler and a water tank ... we have gas however the boiler has completely cut out and there is no hot water or heating, the pressure on the tank is very low... how do I increase the pressure? I have tried turning both valves but nothing happens - pictures for...

Hi All, recently, when I turn the bath hot tap on, just slightly, a very loud shuddering, like a pneumatic drill, can be heard from the pipes/floor/tap? When I turn the tap on fully, it stops. Is this water hammer? It doesn't happen all the time, just every so often. But it is so loud and...

Hi Have moved into Partner's flat and she has a very old Saunier Duval F30E combi. Never seen one before. Pressure will move between 0.5 and 2.6 bar without any topping up of the system. When below 0.6 boiler will not start. I'm use to a little expansion and contraction when heating is on but...

Wonder if you guys can tell me if this is right/wrong. I've recently had a 32kw rapid plus commissioned, all seems to be working well. But I've noticed that when the cold tap/toilet is used, the boiler status number changes and you can hear the boiler internals working... (pump/igniter?) The...

Hello and thank you for reading this message. Our hot water cylinder has no manufacturer name on it so I cannot find a manual. The system is fed directly from the mains with new gas condenser boiler, cylinder, and container above the cylinder looking like a pressure cylinder. The system feeds 2...

Hi all, we have just bought a new place and the water pressure/flow rate out the hot taps is very low. There is a Condensing Combi boiler, Worcester Greenstar 28i Junior that is in the loft. So there is a ground floor and a first floor in the house and then above that is the loft. I have had...

Glow worm betacom 28a. I have done as much googling and YouTubing as I can guys but still no joy

Hi all, first post here and have tried to find some answers for my question but no joy. Moved into a house and needs some upgrading, including the boiler/radiators. Ideally I wanted a combi installed in the toilet downstairs to free space in the bathroom (our current system takes up about 1m sq...

Hi there, I've got a tricky problem so hoping someone out there might be able to help me. At the moment our upstairs radiator closest to the boiler isn't heating up properly at the top. I tried bleeding the radiator thinking it was trapped air, but when I open the valve fully, no air comes...

Hi all, I believe we have a Vaillant Turbomax boiler although I'm unsure of the exact model number. The pressure has been low for a couple of years but only recently on a couple of occasions it has failed to fire up. I just pressed a button and it switched back on immediately. A gas safety...

hey I noticed that my combi boiler was on .5 bar so went to top up the pressure like I normally have before but nothing happens. usually I hear the water running through the pipes but this time I can't hear nothing and the pressure doesn't rise. the only thing that I can think of is that I...

So I've just had a new bathroom fitted - all very nice and all that, but the water pressure in the sink, bath and shower is way down on what it was prior to fitting. Initially when I first turned the tap on upstairs (the refit was done whilst I was on holiday so this was my first use of it), the...

Hi My husband and I have recently completely ripped out our bathroom and installed a new one. Father in law did the pipe work for the new stuff, and we have replaced our old electric shower with a bar mixer shower, which we finished fitting last night. When turning it on, the water runs fine...

I have had plumber in re do my bathroom to put in mains shower rather than electric while away. I got back and pressure was zero which was because hr had drained system. He was called away last minute so was part way through job. He came to finish off yesterday and it turns out he hadnt drained...

Hi folks, I have a Ravenheat RSF820/20 boiler in my flat. Recently it started making a whistling noise when it passes 2 on the pressure gauge. I bled the radiators until the pressure went back to 1. Immediality after opening the boiler, the pressure is past 2 again and is making the whistling...

I have benefitted a lot from posts on this forum and all the helpful advice from professional fitters - so just wanted to post a solution to a problem I fixed in case anyone else is experiencing it. We had a problem with our Intergas Combi boiler (a brilliant boiler BTW). The pressure level...

hi all, I've just noticed I had a couple of radiators that needed bleed upstairs tonight in our new home. I started to bleed the radiators and noticed that while I was able to let alone ir out, it was not followed by water. After doing this a few times I noticed the radiators where getting...
