Backflow Prevention Installation in Katy — Protect Your Water Supply
If your home or business has an irrigation system, fire suppression system, or a connection to a secondary water source, a properly installed backflow preventer is often required by local water authorities — and for good reason. Without one, contaminants from lawn chemicals, standing water, or other sources can flow back into your drinking water supply under certain pressure conditions. Ory’s Plumbing Services has installed backflow prevention assemblies for homeowners and light commercial customers across Katy and West Houston since 1995.
We identify the right device for your specific application, install it to code, and provide the documentation you need for compliance with your local water authority. Family-owned, licensed MPL 41229, and upfront on price before any work begins. We serve Katy, Cinco Ranch, Cross Creek Ranch, Cane Island, Fulshear, and surrounding West Houston communities.
📞 (281) 829-9828RPZ Valve Installation
Reduced pressure zone (RPZ) assemblies are the most robust type of backflow preventer and are required for higher-risk connections like irrigation systems with chemical injectors or commercial properties. We size, install, and test RPZ valves to meet local code requirements.
Double Check Valve Assembly
Double check valve assemblies (DCVAs) are commonly used for lower-risk cross-connections such as fire suppression systems and general commercial applications. We install and test DCVAs to the specifications required by your water authority and applicable plumbing codes.
Pressure Vacuum Breaker Install
Pressure vacuum breakers (PVBs) are a cost-effective solution for residential irrigation systems and are among the most common backflow devices in Katy-area homes. We install PVBs at the correct height and location to meet local plumbing code and water authority requirements.
Irrigation Backflow Preventer
Sprinkler and drip irrigation systems require a dedicated backflow prevention device to protect the potable water supply. If your irrigation system doesn’t have one or the current device is aging, we can assess the best replacement and install it cleanly and to code.
Fire Suppression Backflow Device
Fire line backflow assemblies have specific requirements separate from other plumbing installations and must be testable annually. We install the appropriate assembly for your fire suppression system and can coordinate initial testing and reporting at the time of installation.
New Construction & Replacement
Whether you’re building a new home, adding an irrigation system, or replacing an aging backflow assembly, we handle installation from start to finish — including permit coordination, proper placement, and code-compliant documentation for your records.

Backflow Prevention Installation FAQs — Katy, TX
What is a backflow preventer and do I need one?
A backflow preventer is a mechanical device installed on your water supply line that stops water from flowing backward into the clean water supply. If your property has an irrigation system, fire suppression line, or a connection to any non-potable water source, a backflow preventer is typically required by your local water authority and Texas plumbing code.
What type of backflow preventer do I need for my irrigation system?
The right device depends on the specific risk level of your irrigation setup and what your local water authority requires. Residential irrigation systems in the Katy area most commonly use a pressure vacuum breaker (PVB) or RPZ valve. We assess your system and recommend the appropriate device after inspection — we don’t guess without seeing it first.
Is a permit required for backflow preventer installation in Katy?
In many cases, yes. Permit requirements depend on the type of installation and your local jurisdiction. Ory’s Plumbing handles permit coordination as needed and ensures every installation meets applicable plumbing codes, so there are no compliance headaches after the job is done.
How long does a backflow preventer installation take?
Most residential backflow preventer installations are completed in a few hours. Commercial installations or those requiring additional plumbing modifications may take longer. We’ll give you a clear timeframe and upfront pricing after assessing the job — before any work begins.
Where should a backflow preventer be installed?
Placement depends on the type of device and its application. RPZ valves, for example, must be installed above ground at a height that allows for drainage. Pressure vacuum breakers must be installed above the highest outlet they protect. We determine the correct placement during our assessment and install to code.
If your property needs a new backflow preventer — or you’re replacing an old one that’s failed — Ory’s Plumbing is ready to help. We’ll assess your system, recommend the right device, and install it properly the first time. No pressure, no hidden costs, no surprises after the job is done.
