SWING CHECK VALVE LOCATION
•
Water flow
MUST
be in the direction of the arrow.
IMPORTANT:
Locate the Swing Check Valve at the lowest
possible position in the plumbing system. Allow for a
minimum of 18" water column. The weight of the water
column assists in a greater valve seal and function.
MAINTENANCE
The clear cover permits easy inspection of the Swing
Check Valve. If necessary, the valve can be disassembled
for inspection of the o-ring and valve assembly. Before
reassembly, lubricate o-ring thoroughly with appropriate
silicone lubricant.
