I have a recently installed sealed system (Keston 25) with Boss presurised bottle.
The problem is that after a couple of weeks the pressure is lost (from 1.5 bar to 0) in 2 hours which means continuously re-pressurising and it shuts down overnight. The plumber says it is due to a leakage in the old pipework (he used the old radiator network pipes for the new rads). he has put leak-seal liquid into system wthout any joy.
His proposal is now to dig up the old pipes and replace them or seal as necessary, at great cost.
After a few run ins with the plumber Im not sure I can trust his judgement.
Can you advise as to whether it could be something else in the installation process that may save me time and money ?
Thanks
