Apollo 3820101 Vacuum Breaker

The Apollo 3820101 vacuum breaker is a brass plumbing component designed to prevent back-siphonage in bathware installations. It features a 1/4 inch FNPT connection for direct integration into compatible piping systems. The unit meets ASSE 1001 standards for atmospheric-type vacuum breakers. It suits residential and light commercial applications requiring reliable cross-connection control.

Sustained Pressure and Temperature Performance

Rated for a maximum pressure of 125 psi, the valve maintains its sealing integrity under continuous supply pressure. The silicone seal operates across a temperature range up to 212 degrees Fahrenheit without degradation. Brass construction resists corrosion during prolonged exposure to potable water. These ratings ensure consistent backflow prevention during extended draw cycles.

ASSE 1001 Standard Constraints

The ASSE 1001 listing certifies this device for atmospheric, non-continuous pressure applications only. It must be installed at least 6 inches above the flood-level rim of the fixture it serves. The breaker cannot be subjected to backpressure or used downstream of shut-off valves that create continuous pressure. These limits define the correct installation envelope for code compliance.

Questions about this item

Will the brass body and silicone seal handle continuous 125 psi pressure without leaking or overheating?

The brass construction and silicone seal are rated for 125 psi maximum pressure and a temperature range up to 212 degrees F, so continuous operation within those limits is supported.

What pipe fitting do I need to connect the 1/4 in FNPT inlet on this vacuum breaker?

You need a mating 1/4 in MNPT threaded pipe or adapter to join the female NPT connection on the unit.

Can this ASSE 1001 vacuum breaker stay installed on a legacy 1/4 in brass supply line?

Yes, the 1/4 in FNPT threads and ASSE 1001 compliance let it thread directly onto existing 1/4 in brass piping without modification.
