I "accidently" let all the air out of the expansion vessel through the valve at top of boiler.(long story) The problem was the Air pressure switch which has now been replaced C/H worked for about half an hour then cut out cause no air in expansion vessel? Now nothing working.
Thanks for reply
Will that drain the water out? It says in the FAQs section to NEVER use PRV to drain water out says to use drain cock that I cannot locate.
Hi I need to repressurise my boiler but I cant find drain cock to drain the system first. I have seen the method in FAQ but the location of drain cock cannot be found. Is there another way of draining system through a radiator for example?? Thanks
