Apollo 4ALF-200 Series Backflow Preventer
The Apollo 4ALF-200 Series is a reduced pressure zone backflow preventer built for potable water systems requiring lead free components. Its bronze body meets low lead regulations for safe drinking water installations. The unit protects supply lines from both back siphonage and back pressure contamination risks.
Lead Free Bronze Body with FNPT Connections
The body uses lead free bronze rated for a maximum pressure of 175 psi and temperatures from 33 to 180 degrees F. Female NPT threads allow direct connection to standard piping without extra adapters. The assembly measures 10 7/8 in length, 2 7/8 in width and 7 1/8 in height for tight mechanical rooms.
Certified to ASSE 1013 and CSA B64.4 Standards
This preventer carries ARRA, ASSE 1013, CSA B64.4 and USC FCCCHR approvals for cross connection control programs. The reduced pressure zone principle requires periodic testing and maintenance access to verify relief valve operation. Installers must allow clearance for test cocks and potential discharge during relief events.

Questions about this item
What does the ASSE 1013 standard cover for this backflow preventer?
ASSE 1013 certifies the device as a reduced pressure zone assembly for backflow protection. It verifies performance under continuous pressure up to 175 psi and water temperatures up to 180 °F.
What pipe thread and clearance does the 1/2 in FNPT connection need?
The unit uses 1/2 inch female NPT threads. It measures 10 7/8 in long, 2 7/8 in wide and 7 1/8 in high, so allow that envelope plus wrench swing space.
How is the Apollo 4ALF203A2F installed and what step is often missed?
Install horizontally on a cold or hot line between 33 °F and 180 °F. Flush the line first; debris is the most common cause of check valve fouling.
