I am trying to find the name of a style of tap.
Its the one you often find in public toilets, you push it down water comes out, let it go it pops up and water stops. does that style have a name if so what is it please.

They are called non concussive taps or self closing taps depending on manufacturer. Som can be adjusted for rate and delay.
