Bath Mixer, Shower Pump Fed and 15mm versus 22mm

[darrenh]

Hello all

I sent a post a few weeks back about the fact my shower pump feeds my bath supply (well it will soon).

The hot and cold feeds are both 15mm into a shower/bath control valve (chrome thing there to look nice).

Anyway, should I be using a 22m outlet from the valve into the bath filler as the shower pump will feed the 15mm cold and hot inlets at a powerful rate - when mixed it sort of seems logical to then have the valve outlet at 22m to 'slow it down' to the bath filler.

Any thoughts kindley accepted!

Maybe I need to be a bit clearer on this one.

If i have the hot and cold two feeds into a mixer valve from a shower pump running 15mm, will I be ok having the outlout of the mixer valve in 22mm to slow down the flow?
