Are there any plumbers amongst us that can offer so advice??
Today I took it upon myself to drain my central heating system and replace the radiators and fit TRV's.
All rads are done, all valves fitted, and I have filled the system back up, bleed all the radiators, and got no leaks
However now my hot loop is making on hell of a racket, the pipes are banging and rattling and it keeps venting hot water into my header tank in the loft,
So Iím guessing that there is some air trapped but how can I get it out? Or will it push it out its self??
There is a bleed valve next to the hot water storage tank in the airing cupboard but no air is coming out of there, just water.
Should there be another valve that needs bleeding off??
If none of this makes sense please let me know and Iíll try and clarify it a bit further.
