which has had poor pressure since installing a new tap which I presume has a
ceramic valve. The pump will be installed in the airing cupboard close to
Anyway I'm digressing. To run some new pipework to the repositioned
bath/shower valve I was considering Speedfit/Hep 2o etc. It will be easier
to route around ceiling joists etc and should minimise joints, and bends
will be smooth arcs etc. The pipework I will be connecting to with the Hep
2o is existing 15mm copper, not ideal but it will have to do.
Looking at the joints, the manufacturers recommend sleeves are used to
support the pipe internally, I presume to stop it being crushed. Bearing in
mind its only 15mm pipe, will these sleeves restrict to any great degree the
To join the pipe to the existing copper I was considering the use of a full
bore valve, such as a stopcock. I seem to think service valves etc will
restrict flow? In this way I make the joint and also have a convenient way
of shutting the supply off if needed. Should I be using brass compression
valves or hep 2o variety to make the copper/Hep 2o pipe joints??
Whats best Speedfit or Hep2o ?
