  1. Backflow prevention device testing

    A Licensed Master Plumber will:

    1. Inspect your device. To make sure your device is up to code, we'll need to shut off your water for about 30 minutes.

    2. File the paperwork. We'll handle filing the test reports with the DEP.

    3. Send you reminders. We'll let you know when your BPD is due for its annual test, so you don't get fined.

    Average time to complete: 1 hour

    No matter the service, we offer:

    • 1-year labor warranty. We stand behind our work 1 year after your backflow prevention service.

    • 100% satisfaction guarantee. If you're not 100% thrilled with our service, we'll make it right.

What is a backflow prevention device?

A backflow prevention device is a valve that’s installed on a private water line to prevent contamination of public drinking water. The BPD acts like a one-way gate that allows water to flow into your plumbing system, but won’t allow it to flow backwards out into (and contaminate) the public water supply.

NYC requires most commercial buildings and facilities install a BPD and test it annually. If you don't do either, you could end up paying expensive fines. Learn more about NYC's backflow requirements on the DEP backflow prevention page.

Backflow prevention device installation

We will:

Average time to complete: 1–3 days

  1. Give you an on-site estimate, so you know exactly what you'll pay before any work begins.

  2. Hire a professional engineer. We'll save you the hassle and directly hire an engineer we know and trust.

  3. Design a backflow prevention plan. Our Licensed Master Plumber will work with the engineer to design a plan that complies with code set by the NY Department of Environmental Protection (DEP).

  4. Submit the plan for approval to the DEP. Once we get approval, we can begin installing your BPD.

  5. Install and test the device. We won't leave until we make sure it's working properly and according to code.

  6. File the paperwork. We'll take care of filing the test reports and any other paperwork with the DEP.
