Your Go-To Backflow Testing Team in Petaluma
All Star Plumbing has been serving Petaluma and the greater Sonoma County region since 1992. Our team, led by third-generation plumber and owner Zack Kirtlink, brings over 50 years of combined experience in all aspects of plumbing and water safety systems. We understand Petaluma’s unique infrastructure, from the cast-iron drain systems in historic downtown ironfront buildings to the modern PEX and PVC lines in East Petaluma neighborhoods near Adobe Road.
Backflow testing isn’t optional in California; it’s a mandated inspection that ensures your property’s water supply remains safe from reverse-flow contamination. We handle the entire process: testing your backflow prevention device, documenting the results for compliance, making repairs as needed, and filing the required certification paperwork with your local water authority. Commercial properties, irrigation systems, fire sprinkler systems, and multi-unit residential buildings are subject to these regulations, and we’re equipped to certify them.

Why Shouldn't You Delay Backflow Testing?
Regular backflow testing is an essential safeguard. If a backflow prevention device fails or isn’t tested regularly, contaminated water can flow backward into your home or business supply line, potentially exposing your family or customers to hazardous chemicals, sewage, or agricultural runoff. Beyond health risk, non-compliance carries real consequences:
- Failed inspections on home sales, refinances, or property transfers — a failed backflow test can delay or kill a real-estate transaction.
- Municipal citations and fines — Sonoma County Water Agency and local code enforcement conduct compliance audits, especially on commercial and multi-unit properties.
- Liability exposure — if contamination occurs and your device wasn’t certified current, you bear legal and financial responsibility.
- Service interruptions — some water authorities will restrict service to non-compliant properties.
Testing takes less than an hour and costs far less than dealing with a health emergency, failed sale, or code violation. Annual or biennial testing (depending on your device type and local requirement) keeps you compliant and your water safe.

What Our Customers Are Saying
Frequently Asked Questions (FAQs)
Backflow occurs when water reverses direction in your plumbing system, potentially drawing contaminated water from landscaping systems, fire sprinklers, boilers, or sewage lines back into your home or business’s drinking water supply. Petaluma’s mix of older Victorian and Craftsman homes, newer residential construction, and agricultural heritage means a variety of water systems—all vulnerable to backflow if not protected. Backflow prevention devices stop this reversal, but they must be tested annually or biannually to ensure they’re working.
California law requires testing frequency based on device type and local jurisdiction. Most residential properties need testing annually; some commercial and industrial devices require biennial testing. Sonoma County Water Agency and Petaluma municipal code specify the exact schedule for your property type. We’ll advise on the correct interval when we inspect your device, and we’ll remind you when the next test is due.
Yes. We certify backflow prevention devices on commercial buildings, multi-unit residential complexes, fire sprinkler systems, and irrigation systems throughout Petaluma. Commercial properties often have more complex backflow requirements, and we handle those certifications routinely. Fire sprinkler systems have their own compliance timelines, and we manage both.
If the device doesn’t pass, it means it’s not protecting your water supply effectively. Repair or replacement is necessary before you’re compliant. We’ll quote the repair or replacement cost upfront, and once it’s complete, we’ll retest and file the certification. A failed device is a liability—don’t delay addressing it.
Most tests take 30–60 minutes. We’ll arrive on schedule, perform the test, document results, and review findings with you on site. If the device passes, we file your certification paperwork immediately. If repairs are needed, we’ll discuss options before you decide to proceed.
Not if you’re required by code. Even if you’ve never noticed a problem, a non-compliant or untested device puts your water supply at risk and makes your property non-compliant with California and local law. A failed inspection or citation is far more expensive and disruptive than scheduling a test now.
