Water Standpipes, Keys and Bars
Standpipes,
keys and bars are used to obtain water from a pressurised mains supply
via underground hydrants. The standard outlet for underground valves
according to BS 750 is 2.5" BSRT male.
Standpipes
have as standard a 2.5" BSRT female inlet, which is compatible
with our underground hydrants. Standpipes are supplied either with single
or double head outlets. Outlets are 2" female instantaneous with
single twist release (BS 336). The double-head type is supplied with
one blank plug as standard. Contractors' standpipes are supplied with
a brass double check valve as standard.
