Had a problem with the bathroom rad not heating properly, there is always a lot of air to bleed off.
It is on the ch system - not the hot water heating.
When it was re-sited to a new bathroom plumber had to route the feed pipe under some existing 22mm hot and cold water pipes. He dropped the feed pipe about 3" and then routed back up to the rad, thereby forming a short, say 2' u-bend.
Could this u be allowing air to be trapped on the feed thereby causing the failure to heat.
If yes - any ideas how to fix?
