pipe run

[pauls]

just wondering if it would be better to take 22mm off pump to shower and reduce down to 15mm just before i take the tails up the wall. length of run is about 3 metres or should run be any different in 15mm.

pump is 2 bar
cant remember the make customer ordered it when he ordered the suite

The pipe sizes requires will be in the pump manufactorers instructions but if 2 bar would assume should be run in 22mm,this will require to be 22mm to shower mixer valve,including up wall run

cheers puddle

its a mixer shower i dont think i have ever come accross a 22mm mixer if it is 15mm i take it the best place to reduce would be up the wall run before spliting off to marry up with mixer valve
