WHAT IT SHOULD COST

What backflow testing should cost.

No sticker shock here — the annual test itself is one of the cheaper compliance line items you'll have. These are honest Sacramento-region ranges for 2026. They're estimates to set expectations; your matched tester gives the firm quote.

Single assembly — annual test

Most common. One RP, DC, or PVB tested and filed.

$35 – $90

Each additional assembly (same visit)

Multiple assemblies on one property are usually discounted per unit.

$20 – $55

Test + minor repair (rebuild kit)

If the test fails, a worn check/relief valve rebuild — parts + labor.

$150 – $350

Assembly replacement

Older or failed assemblies replaced; varies by size and type.

$400 – $1,200+
