CLOSED I want connect a shower pump -can I use PEX
Jun 28^th, 2009, 12:25pm

You can it turns out.

I have purchased a CT75 Salamander pump for my shower. I have a few questions because my airing cupboard is crowded.
I will be installing below the hot water cyl. (gravity fed from upstairs tank). The tee-off from cyl has valve connected to shower inlet. I want to disconnect at valve and then connect to pump and return to shower inlet.

I can use copper but it becomes complicated. Can I use PEX for cyl to pump and pump to shower inlet port? Something like FloPlast PE-X Barrier Pipe 25m x 15mm from screwfix.

It is flexible and I can route more easily. Is this OK?
Can it take the water pressure of pump at 2 bar?
The pump seems to have press fit AV pipes - will the PE-X work?
