Boiler losing pressure mystery, HELP!
Anonymous user 23/02/2024 - 3.42 PM
My boiler is losing 1.5 bars of pressure from 20:00 to 07:00. We’ve got British Gas home care and so far we’ve had the boiler isolated and it retained pressure. When the boiler was unisolated the pressure dropped down to 0 pretty much instantly, indicating it was an issue with the central heating. ADI leak detection was called out because British Gas’s third party was going to be weeks. They used acoustic, damp meters and gas tracing but found no leak. The gas tracing was at 4 bars or pressure for 90 minutes and no drop off pressure. British Gas came back out to check the boiler once again and stating nothing was wrong with the boiler but noticed a weeping radiator valve which was replaced. This is no longer weeping. The boiler continues to lose pressure and a F4 leak sealant has been used now. However, the pressure still drops, there’s no air in radiators each time I pressurise the boiler. So my question is this caused by a leak or is it the boiler?
Are you a tradesperson and able to answer this question?
