Suitable non-return valve for low pressure

Axel · 14 Dec 2010

I want to fit a non-return valve to a bath mixer but the head is only around 1.5m (before the positive head pump kicks in), so what is the best type of 22mm non return valve that has the least impedance to flow?

You'll find an ordinary single check will be fine. 1.5m is enough head to open them for the pump to "see".
