About This Service
Backflow occurs when water flows backward in a plumbing system — potentially allowing contaminated water from irrigation systems, pools, or commercial equipment to enter your clean water supply. Most commercial properties and many residential systems with irrigation are required to have backflow preventers tested annually. H3 Plumbing & Drains is certified to test, repair, and replace backflow prevention assemblies and file the required reports.

Frequently Asked Questions
Who is required to have backflow testing?
Most commercial properties, businesses with irrigation systems, and many residential properties with in-ground sprinkler systems are required by the water utility to have annual backflow testing. If you've received a notice from your water company, call us to schedule.
What happens if my backflow preventer fails the test?
We can repair or replace the assembly on the spot in most cases. Failing to have a non-compliant backflow preventer repaired can result in your water service being shut off, so it's important to act quickly.
How long does backflow testing take?
A standard backflow test takes about 30–60 minutes per device. We complete the paperwork and file the required certification with your water authority.
