    Low water pressure after DIY work

    I replaced some plastic pipes and fittings on my mains inlet under the sink with copper today. First time ever attempting plumbing, but it seems ok with no leaks. At first it was all hunky dory, but I later noticed my water pressure had gone down. I’ve attached a pic. The section from the check...

    Boiler noise/pressure loss

    I found this forum on google as I need advice. Before I start, I know nothing about plumbing or central heating systems other than what I’ve read online. I’ll explain, basically we rent, sane place for 8 years and for quite a number of those years we’ve had to top up the boiler pressure way more...

    Recommended pressure bar to re pressurise system?

    Hi, I have a new boiler Ideal "Heat only" 24kw with a new Indirect unvented hot water cylinder and two expansion tanks. The plumber who fitted the system a few months ago told me how to re pressurise the system by opening two valve taps to introduce mains fed cold water to the system and...

    Loosing pressure but no air in rads

    Hi..so the Baxi combi at my folks' house has lost pressure twice over a period of a couple of weeks since they started using the central heating this winter....but each time it's happened there's no air build up to be bled from any of the radiators. Am I right in thinking that the pressure drop...

    Repeated complete pressure loss

    Can it be anything other than a leak? The reason I ask is that I have had 4 plumbers/heating engineers out over the past 3 months and none are able to figure this out. System boiler powering a mixture of radiators and UFH. No detectable leaks by the rads, by the manifolds or really anywhere in...

    Hi everyone.! I have a Betacom 2 24 Boiler ( 10 years old) and have been having issues with the pressure dropping. So far, I have had 2 Engineers visit, resulting in fitting a new Pressure Release Valve and a new Expansion Vessel. Both to no avail so far. The pressure tends to drop down to...

    Vailant ecotec pro 28 pressure

    Hello. I’ve lived in the property for 4 years and anytime the pressure got low (0.8 bar) I would use the fill taps to release more water into the system. Ever since British Gas did their annual boiler check about 3 months ago, I’ve had to do this too up method more and more. My pressure is now...

    My Worcester boiler is losing pressure. It only happens after the boiler has been on and it loses approx 0.5 bar each time. The expansion vessel was replaced last year and no improvement, I have checked the rads, no issues, also no obvious water patches on walls ceilings etc. I have also used...

    Which is the better (or valid) pressure balancing loop?

    I am trying to make a pressure balancing loop for body jets in a shower. I have limited space so the loop has to be similar to those drawn. I just need to know which one would work and if both, then which is better. Thanks in advance :)

    Hi I fitted a bath/shower 12 years ago and a few months ago it developed a leak. It was basically at a coupler on 40mm solvent where my new white PVC joined the existing grey PVC. I cut a hole in the ceiling and could also easily view it with the bath panel off but not access it from there...
