Short answer: In New Jersey, commercial irrigation backflow preventers are tested annually by a certified backflow tester, and the results go to your water supplier and/or town. We schedule it, test it, fix failures, and send you a copy of the report.
Why it's required
A backflow preventer keeps irrigation water — which can carry fertilizer and pesticide residue — from being pulled back into the public drinking water supply. Because of that risk, NJ's plumbing code and local water suppliers require testable devices on commercial properties to be checked every year. Ocean Township, for example, states that commercial properties must be tested annually.
What we do
- Track your due date (or your supplier's notice date).
- Test the device with calibrated gauges.
- If it fails, quote and complete the repair, then retest.
- File results with your water supplier and town as required, and send you a copy.
Device types we test
- Reduced pressure zone (RPZ) assemblies
- Double check valve assemblies (DCVA)
- Pressure vacuum breakers (PVB)
Avoid fines and shut-off notices
Missed tests can lead to violation notices from your supplier. Contract customers have tests scheduled automatically and a reminder before the deadline.
