Description
The PH Series...eliminates
the problem of nuisance
cycling of the safety relief
valve when a backflow
preventer or check valve is
present in a domestic hot
water system. Utilizing
Flexcon’s all butyl diaphragm
system, they provide a
reservoir for expanded water
volume and help to prevent
dangerous over
pressurization. The diaphragm
is permanently separated from
the tank’s air charge. The PH
tanks also feature a
Stainless Steel system
connection for maximum
corrosion resistance.
