Annual Backflow Certification in Katy, TX

Who needs the yearly test

You need annual backflow certification when your water system has already required a device and it is time to prove it still holds. That usually means:

Some Harris County MUDs do this in writing. Harris County MUD 81 in 77450, for example, requires testable devices on pools, spas, and sprinklers and yearly testing of those assemblies. Other districts write similar rules. A district may also charge its own admin or filing fee. That fee belongs to the water system. It is not Ory’s test price, and we do not quote district fees as ours.

A shutoff threat in that letter is a public-system enforcement tool, not a sales pitch. If the report is late, the water authority can restrict service until a current test is on file. The assembly owner, not the plumber, stays on the hook for that deadline.

This page is for homeowners, HOAs, and light-commercial properties in Katy who already have a device and need it certified this year. If you do not have an assembly yet, that is installation, a later sibling page. If you only want a one-off field test with no yearly filing, that is a different visit. If the device already failed and will not hold, that is repair.

• You got a compliance notice, a reminder, or an overdue letter from your MUD, Fort Bend system, or City water purveyor
• You have an irrigation backflow, a pool or spa feed, a domestic assembly, or a commercial RPZ
• Last year’s report is about to expire, or already has
• A new buyer, a property manager, or a tenant just inherited a device that was never put on the yearly calendar

How the visit works

Licensed Master Plumbers do this work at Ory’s. In Texas, annual assembly tests are typically performed by a TCEQ-licensed

We will not sell this visit as a new install, a fireline test, or a class that licenses you as a tester.

1. BPAT. We do not claim that card on this page.
2. Confirm the notice. We look at the letter or the portal record: which assembly, which water system, and where the report has to land.
3. Find and identify the device. RPZ/RPBA, DCVA, PVB, or SVB. Irrigation box, pool feed, domestic line, or commercial
4. RPZ. We do not treat a fireline as part of this visit.
5. Test with a calibrated gauge. Each valve and check is tested to the assembly type. The result is pass or fail, not a guess from the driveway.
6. Pass. We write the certification and file with the system you are in. Some districts want the report emailed. Some use BSI,
7. Vepo, or Envirotrax. Some still want TCEQ Form 20700. You keep a copy. You still own the deadline next year.
8. Fail. The assembly cannot be certified as-is. It needs repair or a rebuild, then a retest, before a passing report can be filed. Repair is a separate service and a later sibling page. We will tell you it failed and what has to happen next. We will not mark a failed device as passed.
9. Upfront price before the work. You get a written price after we see the assembly and the filing path, not a coupon.
