Common Questions

Can this kit be used for continuous pressure applications?
No, the 38-100 series is an atmospheric vacuum breaker designed for intermittent use. It should not be under pressure for more than 12 hours in any 24-hour period.

Does this kit work with the lead-free (LF) versions of these valves?
Yes, the internal rubber and plastic components are compatible with both the standard bronze and the lead-free Apollo vacuum breaker models in the specified sizes.

Why is my vacuum breaker leaking from the top cap after installing the kit?
Leaking usually indicates debris on the seating surface or an improperly seated float gasket. Ensure the valve body is flushed of all scale and mineral deposits before installing the new repair kit components.
