Shower Waste - What volume of water is it rated for ?

[self builder 123]

Hi

We have a MacAlpine shower trap ( 50mm water seal with an 85mm flange ). This is fitted to the stone tray from Just Trays which has a 50mm hole cast in the bottom of it.

The trap has a 40mm outlet which connects into a short run of 40mm pipe which runs at a gentle gradient to the 110mm soil stack.

What volume of water is this waste able or rated to handle ?

I take it that the 40mm pipe would never run at fully capacity ?

Cheers

i seem to re-call something i read while fitting a wetroom about 20 litres a minute not sure if that was 32mm or 40mm pipe not many set ups come near to this i`m sure somone will clarify!

Capacity depends on the fall, take a look at this http://www.brettmartin.com/building/soilwaste/technical_guide/design/appliancedischargevolumes.aspx
