Protect your water supply with professional backflow prevention from Holloway Plumbing. Certified service for homes and businesses in Kerrville, Boerne, Fredericksburg & across Hill Country.

Keep Your Water Supply Safe with Holloway Plumbing

The water that enters your home or business should be clean, safe, and flow in only one direction. Backflow is the unwanted reversal of water flow, which can pull contaminants from a non-potable source back into the clean public water supply. This creates a serious health risk for your family, employees, and the entire community. A simple pressure change in the main line is all it takes to cause a backflow event.

At Holloway Plumbing, we are certified to protect our communities throughout Texas Hill Country from these risks. We provide expert backflow prevention services, including device installation, testing, repair, and compliance management for homes and businesses in Kerrville, Boerne, Fredericksburg, and everywhere else in our neck of the woods. We’re here to help keep our community safe, and keep everyone operating at full capacity.

Understanding Backflow Risks on Your Property

Any point where your clean water system connects to a non-potable water source is called a cross-connection, and it poses a backflow risk. Common cross-connections in Hill Country properties include, but may not be limited to:

  • Residential Risks: Irrigation and sprinkler systems, garden hoses with chemical sprayers attached, swimming pools, and boilers.
  • Commercial & Business Risks: Fire sprinkler systems, large-scale boilers, commercial kitchen equipment (dishwashers, soda fountains), medical and dental office equipment, and salon sinks.

Protecting these points is not just a good idea, it’s often required by law to safeguard public health.

Backflow Prevention Devices: The Right Tools for the Job

To stop backflow, a specialized backflow prevention assembly is installed at the cross-connection point. The type of device required depends on the level of hazard.

  • Reduced Pressure Zone (RPZ) Assemblies: Used for high-hazard situations where contaminants could cause serious illness. These are common in commercial and medical settings.
  • Double Check Valve Assemblies (DCVA): Used for low-hazard applications where contaminants are non-toxic but still undesirable.
  • Pressure Vacuum Breakers (PVB) & Spill-Resistant Vacuum Breakers (SVB): Typically used to protect irrigation systems.
  • Air Gaps: A simple physical separation between a water outlet and a potential contaminant source, like the gap between your kitchen faucet and the sink drain.

Frequently Asked Questions – Backflow Prevention

How often does my backflow preventer need to be tested?

Most local water authorities and state regulations require commercial and residential backflow preventers (especially on irrigation and fire systems) to be tested at least once per year by a licensed tester.

Visible leaks, continuous dripping from an RPZ relief valve, discolored water, or a notice from your water provider are all signs that your device needs immediate attention.

An RPZ provides a higher level of protection for high-hazard situations by including a relief valve that will discharge water if one of the check valves fails. A Double Check is used for lower-hazard scenarios.

A standard test can typically be completed in 20-30 minutes. During this time, the water supply downstream of the device will be temporarily shut off.
