Hi,
Called to a job where the above was fitted (type 36022). Customer having to usually lower shower hose to get water flowing and temperature fluctuating (lack of hot).
Unit mounted in loft.
Cold feed from 15mm tank connector at side of unit.
Hot feed taken from horizontal take off on cylinder which is about 400mm below the Grohe unit in airing cupboard. It is tee'd off in 22mm Speedfit then immediately reduced to 15mm and routed through ceiling into Grohe unit with a series of 15mm Speedfit fittings!
Obviously, this is where I believe the problem lies!
Any suggestions as to improving the hot pipework? I was thinking of removing the Speedfit and fitting a copper 22mm tee from the horizontal take off but cannot decide whether to bring the pipe out towards the front of the cupboard a short distance then vertical in 22mm and elbow/reduce to 15mm next to Grohe.
Would it be a good idea to form a 'U' bend when coming off horizontal take off to reduce any air locks?
Many thanks in advance,
Gary.
