pressure

Hi, I've got a Main combi eco 25. When CH is running a lot, the pressure reaches 3 bar and the PRV seems to kick in as I can see a slow dribble from the outside pipe. I think what happens next is when CH is off for a while, the temp drops and the pressure also drops low enough so that the...

Hi, I moved into a the upper part of a two storey house in April this year. The previous owners installed a Baxi Platinum combi boiler a few years ago which was working fine until about 4 weeks ago. I started getting E133 errors on the boiler (the instruction flap on the boiler lists this as a...

Hello, Recently moved to a new rental place. The Vaillant EcoTec Pro 24 boiler was empty (I think for quite a while), refilled it via the loop to 1.5 bar & bled the radiators to remove any air. One of the valves (the smaller handle) in the filling loops leaks very slightly but I don't think...

Hi all Unfamiliar boiler and was told over the phone how to top up the pressure, however the boiler in question is a Vokera Compact HE and the taps/valves underneath the boiler are arranged as follows: Yellow (Left), Black screw valve marked 'Vokera Adjustable Stopcock' (Right). Following...

I have a problem with my Vokera 25he boiler losing pressure when the central heating warms up. The pressure sits steady at 1.5 until the radiators reach temp and then drops to zero within the hour. I have 5 radiators on the ground floor and 2 on the first. One radiator on the first floor has...

Hi everyone, I’m having some strange issues with my boiler that has our usual heating guy stumped and I’m hoping one of you friendly DIYers will be able to help. It’s a Logic Combi 24 losing pressure, around 0.5 bar every 24 hours. I turned the boiler off and isolated the central heating feed...

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...
