Features
The Wilkins model 705, with its lead free construction is the perfect valve to be used to pro-
tect against low hazard backpressure or backsiphonage in drinking water systems. Like the
model 700, the 705’s tubular design houses two in-line check valves and is a suitable valve
for providing isolation protection. The Wilkins 705 is one of the most economical ways of
preventing backflow.
