1. Inspect Valve for Leakage Through Seat.
The Guardian
squeeze valve is manufactured from components that
will provide the valve with exceptional durability. The
valve seat is machined from solid stainless steel bar stock
and the valve disc is high durometer synthetic rubber
for positive shutoff and exceptional wear resistance.
However, it is possible that, over time, these components
can wear or be damaged by impurities in the water flow.
Therefore, Guardian has designed these valves so that all
of the wearing components of the valve are removable
and replaceable. Should any of the components wear over
time and the valve begin to leak, the components can be
replaced and the valve will be essentially “as good as new.”
Inspect valve components for wear and replace as required.
2. Inspect Valve for Leakage Around Valve Stem and Bonnet.
The valve stem and bonnet have O-ring seals to prevent
leakage outside of the valve body. These O-rings can over
time wear or deteriorate.
Inspect the unit for signs of
leakage around the valve stem and bonnet. Replace the
O-rings as required.
3. Inspect Squeeze Handle.
The squeeze handle on the valve
is heavy duty stainless steel to withstand bending and
resist corrosion.
Inspect the handle for proper operation.
