Dive Deeper

Run water to check for leakage or backflow
Apply silicone sealant around edge as secondary protection
Confirm valve closes and opens correctly
Optional: use odor tracer spray to check seal

Valve Movement	Smooth open/close on flow

Silicone edge seal increases protection

Adding exterior sealant prevents seepage from surface runoff.
