Backflow Prevention Services
Backflow preventers do one critical job: they keep contaminated water from flowing backward into your clean water supply. If you have an irrigation system, a fire suppression line, or a commercial property, chances are you have one — and chances are your municipality requires it to work correctly.
Protecting your water supply — from residential irrigation systems to large commercial installations.

Tidewater Plumbing Co. installs, repairs, and replaces backflow prevention assemblies of every size, from small residential irrigation setups to large commercial applications.

Signs You Need Backflow Service
- You've received a compliance notice from your water utility

Frequently Asked Questions
- Why does my water utility require backflow testing?
- Municipalities require annual testing of backflow assemblies because a failed device can allow irrigation water, chemicals, or other contaminants to siphon back into the public drinking water supply. It's a public health safeguard — and staying compliant avoids fines or water service interruption.
- My backflow preventer failed its test. Now what?
- Depending on what failed, the device can often be rebuilt with a repair kit rather than fully replaced — a meaningful cost difference. We'll assess it and recommend the more economical route when it's viable.
- Do you handle commercial backflow work?
- Yes — commercial backflow is a core part of our business, from retail properties to larger facilities. We've handled installations that other shops quoted well outside reasonable budgets and timelines.
