FEBCO Product Lines

The 765 pressure vacuum breaker is the common choice for lawn irrigation, guarding against back-siphonage. It mounts above grade, typically at least 12 inches above the highest sprinkler head. For higher-hazard connections, the 825Y reduced-pressure (RP) assembly gives the highest level of protection — against both backpressure and back-siphonage — with a relief valve that can discharge water.

Lower-hazard, continuous-pressure lines use the 850 and 805Y double check assemblies. Keep any FEBCO assembly in service with repair kits — bonnet, check and relief-valve rubber parts. Always confirm the required assembly with your local code.

FEBCO Backflow FAQ

What’s the difference between a PVB and an RP assembly?

A pressure vacuum breaker (PVB) protects against back-siphonage only and is common for lawn irrigation, installed above grade. A reduced-pressure (RP) assembly protects against both backpressure and back-siphonage and gives the highest level of protection. Your local code sets which one is required.

Which FEBCO model do I need for lawn sprinklers?

Many residential irrigation systems use the 765 PVB, but the required assembly depends on your local code and the hazard level of the connection. Check with your water authority before you buy.

Can a FEBCO backflow preventer be repaired instead of replaced?

Usually yes. FEBCO sells repair kits — bonnet, check and relief-valve rubber parts — so a leaking or failed assembly can often be rebuilt rather than fully replaced.

Do backflow preventers need to be tested?

Most testable assemblies — PVB, RP and double check — must be tested by a certified tester, commonly once a year, as required by your local code. Reduced-pressure and double-check assemblies have test cocks for this purpose.
