Rob W Posted January 2 Share Posted January 2 Hello, a tenant's Ideal combi 30 boiler lost pressure and shut down. An engineer re-pressurised the system, however now the pressure gauge is flickering around 1.5 bar and the tenants say the pipework occasionally becomes very noisy before quieting again. I have bled the radiators, only 1 radiator had a tiny bit of air, no change. Any suggestions gratefully received, thankyou. Link to comment Share on other sites More sharing options...
Alan Ambrose Posted January 2 Share Posted January 2 Double check the actual water pressure & flow at the location with something like this https://www.screwfix.com/p/monument-tools-water-flow-cup-weir-gauge/5784k https://www.screwfix.com/p/monument-tools-mains-water-pressure-test-gauge-11bar/82412 If that's OK, there's probably a tiny leak somewhere. Check all the bleed valves for a start and all the radiator entry / exit points for signs of water. A paper tissue will give a good indication of a tiny leak. You can re-pressure yourself if you're careful, but it'll happen again if the leak isn't found. Anything changed / happen about the time the problem started?

ProDave Posted January 2 Share Posted January 2 No 1 question is where is the leak and was it fixed? No 2 question is the expansion vessel okay and was it checked. The 2 are very probably related. Link to comment Share on other sites More sharing options...
Rob W Posted January 3 Author Share Posted January 3 Thanks Alan & Prodave, the tenants messaged me midday on a saturday to say the boiler wasn't working, not the best time to find someone. I contacted the agents whom found an engineer whom visited sunday am. His report & bill to agents merely says boiler re-pressurised and radiators bled. I will see if my gas check engineer whom wasn't available on the weekend can bring the gas check forward from march. Thankyou. Link to comment Share on other sites More sharing options...
ProDave Posted January 3 Share Posted January 3 So it is losing pressure but nobody has bothered to try finding the leak? Link to comment Share on other sites More sharing options...
