How often do I need a backflow test?
Once a year at minimum. A device also needs testing right after it's installed, repaired or moved. Your water district picks the due date and normally mails a reminder ahead of time.
What happens if I don't test by the due date?
Water districts typically send a reminder, then a final notice. Continued non-compliance can lead to fees and, in some districts, interruption of water service. If your deadline is close, contact us and mention the date.
Will my water be shut off during the test?
For a few minutes. We close the valves on the device to take readings, so water past it is off briefly, then it goes right back on.
What happens if my device fails the test?
We tell you which part failed and why, and give you a price before any work. Most failures are fixed by cleaning or rebuilding the check valves or relief valve with manufacturer parts. After the repair we retest and file the passing report. See backflow repair.
Who can do a backflow test?
Only a certified backflow prevention assembly tester. Most water districts also require the tester to be on their approved list and to submit results on the district's form or online portal.
Do I need to be there for the test?
Usually not. If the assembly is accessible, we can test without you on site. We just need gate codes, keys to any locking cage, and a contact number in case we find a problem.
Who sends the report to the district?
We do. The report goes to your district the way they want it, and you get your own copy.
How much does backflow testing cost?
It's $105 per device under 4 inches and $175 for 4 inches and up. Filing with your district is included. If a repair is needed, you get that price before we start.
Should I repair or replace a failed backflow preventer?
Most assemblies can be repaired with a rebuild kit. Replacement makes more sense when the body is cracked or frozen, parts are no longer made, the assembly was stolen or damaged, or your hazard has changed and needs a different type. See backflow replacement.
Do homes need backflow testing?
Plenty of homes do, usually because of a sprinkler system, a fire sprinkler line, a pool fill or a well. If you got a notice, your district already has a device on file for your address.
