stop tap

[1john]

is it acceptable to use a full bore quater turn valve (the ones with a handle) as a main stop tap in a domestic property??

 

[kevplumb]

yes

the lwc use them on the mains

Yes, the water regs changed to allow them to be used.

However they also say that individual fittings must be prevented from backflow, where applicable.
