15mm inlet on shower pump

[PetePlumb]

Hi, I am fitting at Stuart turner shower mate eco 1.5 bar.

My question is, can the inlet be from a 15mm source? The provided flexible hose that comes with it is 15mm.

I just cant get get to the 22mm pipe easily.

What are your thoughts?

Cheers

Yes 15mm on a 1.5 bar is fine

Cheers for your speedy response. So you wouldn't recommend going up to a 2 bar? Or is that just pushing the limits. ST pumps seem to do a 2 bar with a 15mm flexible inlet hose.

1.5 twin will be fine only thing to watch is if you need a universal or positive head pump

I think I'll be OK with a positive head pump. I connected one of those push on shower heads to the bath tap and looks like enough flow is coming out.

Would you recommend using 22mm pipe on the outlet of the pump to the shower, or just stick with 15mm throughout.

Thanks again.

If you have 15mm in you need 15mm out
