Hi Have sealed combi system. Drained and put in some cleaner last week. Ran for a week then flushed twice and put in inhibitor. Recharged system and lost 0.7Bar overnight with system not running. Had a slight pressure drop issue for years requiring a top up every month or so but thought it was a leaky valve which I fixed last weekend when system was empty.
Read a few things and dropped pressure to zero and checked that expansion tank pressure was Ok. Pumped up to 0.7Bar with bicycle pump so thought that might help but still losing pressure when nothing on. Then checked condensate drain and plastic tub filled up after about an hour with nothing running. Found a few mentions of potential issue with heat exchanger but nothing specific.
does anyone have any thoughts of things I could check before calling out company we have cover with? Just wanted to make sure its nothing obvious that I could do easily.
Cheers in advance for any help.
