New radiators installed, cant balance system

[Howsie]

Don't touch it. It's your builders responsibility to get it sorted unless he knocked some money off because a blind man was on the pipes. Touch it at your peril as you've given him a get out.

IMHO that work wasn't done by a plumber.

What a shocking job! Definitely not done by a plumber. Even our village handyman would have made a better job than that. Pipes not even straight or bracketed properly. No attempt made to make the job look neat. Bet it's not been pressure tested either. Don't bother attempting to balance it because it'll be a waste of time as it's probably impossible anyway.

I take it you two haven't read the entire post. The job has been rectified by another plumber and is now working properly.
