Lots of leaks in flat, dropping boiler pressure, unsure of cause

Anonymous user 16/03/2024 - 2.37 PM

I also have a problem of a boiler that needs very frequent pressure top ups, - as per the advice of plumbers, I have had the expansion tank, PRV and condenser unit all replaced, and this has made no difference except to my bank account. I've been having annual boiler service, with no issues. Is it possible that I have lots of little leaks in the piping in the walls that I cannot see, that is causing my boiler pressure to drop. I can't exactly demolish all walls to find the leak. What is the solution to this? If the problem is that the plumbing quality of the flat is poor, is it something I need to pay for myself or can the managing agents of the building help? If the problem is poor quality plumbing of the apartments, I can't understand why this issue is only affecting my flat, and not my sisters' who lives upstairs. Recently the tenants who are currently living in the flat notices mould, on the bottom of living room wall, bedroom wall and hallway. Could this be related? I think I need some advice on a lasting solution to this problem. I would not even mind paying for a boiler replacement, but I don't think the boiler is the issue. I feel that the guy who sold me the flat knew about these issues and just wanted to get rid of it; I don't want to do the same to somebody else, I really just want to sort this out!! Thanks in advance for your help.

Are you a tradesperson and able to answer this question?

The only way to check if the pipework/radiators are at fault is to have this pressure checked It would however be difficult to isolate the fault if some pipework is in the walls A pressure check before you made financial outlay on the repairs would have been prudent Mold in the other flat is unlikely to be related to your Robles

Your going to have to isolate the flow and return at the boiler, pressure test and determine wether its the boiler or system causing the pressure to drop. If its the boiler then further investigation would be required into that - which it sounds like you have had done already? However, if its the system with the leak I would first try some fernox leak sealer, leave it for a couple weeks and if that dont work it sounds like you'd need a re-pipe with cerface mounted pipes.

It should be possible to eliminate the boiler from the equation by simply isolating it from the flow and return pipes (pressurise the system), turn off the valves on the flow return pipes under the boiler and leave the system off. Check the pressure gauge on the boiler and see if its dropped, if not then it aint the boiler, if when u then open flow and return ur pressure drops u knowbits in the pipework. Make sure ur noilerbis off when u isolate it!
