Mixer Shower with Pump - Pipe size help please...

[Mark69]

Ok, i will shortly be installing a mixer shower with a 1.5 bar twin impellor pump. Which pipe size would be best? 15 or 22mm ? (inlet & outlet?)

To be honest, I would prefer to do it in 15mm plastic as i already have plenty of that, but if 22mm plastic would be better can go out and buy some more. Please advise.

Thank you.

Whatever the size of your inlets/outlets on your pump are, run the same size pipework. On a 1.5 bar pump they would normally be 15mm, running in 15mm will be fine.
