can a 1.2 bar pump feed 5m of 15mm pipe to a bath mixer?

[cgullcharlie]

I have an existing 1.2 bar pump feeding a shower only about 1m away.

All is good. its connected up close to the hot water cylinder and has its own feed from the loft cold water tank.

I now want to Tee it off to feed a 5 metre distance of 15mm pipe at the end of which sits a happy new bath and bath mixer with shower hose.

Will it cut the mustard?

And should mention I'm adding in 2 basins along the way. Generally not expecting high usage of any of em.

Depends on the flow rate as well as the pressure, hard to say without seeing a performance curve but I wouldn't expect it to run more than one outlet at once

my bad, its actually a 1.4bar Stuart Turner twin showermate.

I was hoping I would be ok with the 15mm runs instead of 22mm as it is pumped. Was easier to route a channel in the walls for 15mm hence why i used it.

Should be fine, unless you expect 30 liters per minute

Closest I can find on the ST website is a 1.5 bar, it'll work OK but you'll probably notice if you're having a shower and someone turns a tap on elsewhere

Unless you run the basin cold tap on it's own when brushing your teeth and burn the pump out

Well thats comforting! Is that a real possibility ?

Surely they can handle one side only for a few minutes? What if some masochistic type wanted a cold shower? Or a very hot one??
