Backflow Preventer Testing in Houston | We Handle the Paperwork

If you own a commercial building or a home with a sprinkler system, you likely receive a letter once a year from the City of Houston or your local MUD (Municipal Utility District). It states that your Backflow Prevention Assembly must be tested by a licensed professional within 30 days, or your water service will be terminated.

Don’t panic. Call Blackmon Plumbing. We are licensed BPAT (Backflow Prevention Assembly Testers). We treat this as a turnkey service: we drive to your property, perform the differential pressure test, place the official “Green Tag” on your device, and—most importantly—we mail the certification report to the water district for you.

About 20% of devices fail the annual test due to worn-out rubber parts or debris.

The “Upsell” Trap: Many testing-only companies will fail your device and tell you to call a plumber to replace it (costing you $800+).

The Blackmon Advantage: Because we are Master Plumbers, we carry repair kits on the truck. If your unit fails, we can usually rebuild it on the spot, re-test it, and pass it during the same visit.

We manage compliance for large properties with multiple devices.

Restaurants: Testing for carbonators (soda machines) and grease trap lines.

HOAs: Volume pricing for neighborhood irrigation backflow testing.

Medical Facilities: Testing for critical isolation devices on X-ray and sterilization equipment.
