San Diego DMA · after a fail
Failed backflow test repair
A fail is a result, not a negotiation. The agency wants a passing report. That usually means a rebuild or a replacement, then a retest. Request that work. This page cannot certify the device and cannot make a fail disappear.
What to send from the fail paperwork
Which check failed if the report says, device type and size, and the retest deadline. If you only have a verbal “it failed,” write that. A tester still has to see the valve.
Do not send a photo of your water bill’s entire account page. The device ID is enough.
Rebuild versus replace
Many RPZs and double-checks take a rebuild kit if the body is sound. Frozen shutoffs, cracked bodies, and obsolete models get replaced. That choice belongs to the person looking at the valve, not to this form.
Ask whether the retest is included. Often it is a separate line.
Typical cost — not a bid
A rebuild plus retest is often a few hundred dollars. Replacement spreads widely with pipe size — hundreds for a small irrigation valve, low thousands for a large commercial or fire-line assembly. Shutdown time on a business can cost more than the valve.
Those are typical San Diego-area ranges, not a bid from this website.
