Apollo 3820106 vacuum breaker — purpose and fit

This Apollo 3820106 vacuum breaker protects bathware plumbing from back-siphonage. The brass body with polished chrome finish suits 1/4 in FNPT connections. It is built for residential and light-commercial fixtures that require ASSE 1001 compliance.

Before ordering — verify your connections

Confirm the supply line uses 1/4 in FNPT threads so the breaker seats correctly. Check that system pressure does not exceed 125 psi and that water temperature stays within the 212 °F limit. The 2 5/16 in height and 21/32 in width must clear surrounding hardware.

Under sustained load — pressure

The silicone seal maintains a tight barrier during continuous 125 psi operation. Brass construction resists creep at the 212 °F upper temperature bound. ASSE 1001 certification confirms consistent anti-siphon performance over extended duty cycles.

Questions about this item

What comes with the Apollo 3820106 vacuum breaker and is anything else needed for installation?

The breaker is supplied as a single brass polished chrome unit with a silicone seal. No extra parts are included, so you will need 1/4 in FNPT pipe fittings and thread sealant to connect it to your supply line.

How do I know the 1/4 in FNPT 125 psi version is the right one for my bathware?

Choose this model when the supply connection is 1/4 in FNPT, the system pressure does not exceed 125 psi, and the temperature stays at or below 212 °F. The ASSE 1001 listing confirms it meets the standard for anti-siphon protection in bathware applications.

What does the 125 psi rating mean once the breaker is installed in a real bathware system?

It means the device is tested to hold backflow prevention up to 125 psi supply pressure at temperatures up to 212 °F. In normal residential bathware pressure ranges well below that limit, the breaker will reliably prevent vacuum siphonage.
