While not all homes may be required to install a backflow preventer, there are a couple of reasons why you may need to, including:
- Public Water System: If your home’s water supply is connected to a public water system, you should install a backflow preventer.
- Fluctuations in Water Pressure: If your home’s plumbing system experiences fluctuations in water pressure, it increases the risk of backflow.
- Presence of Non-Potable Water Sources: Installing a backflow preventer is advisable if there are cross-connections with non-potable water sources such as fire sprinklers, irrigation systems, or private wells, as these can contaminate the water supply.
- High-Risk Fixtures or Appliances: Installing a backflow preventer is recommended if your home has plumbing fixtures or appliances that could create a risk of backflow, such as boilers, hose bibs, or swimming pools.

Backflow Preventer Installation Services
Our plumbing experts will assess the type of backflow your water supply is experiencing. Depending on your specific issue, we can install a custom-made backflow preventer to solve the problem.
- Low-Pressure Systems: Atmospheric Vacuum Breakers (AVB) are suitable for low-pressure systems where automatic vacuum detection is crucial for preventing backflow.
- High-Pressure Systems: Pressure Vacuum Breakers (PVB) are recommended for higher-pressure systems. They feature multiple check valves that respond to pressure changes to ensure reliable backflow prevention.
- General Plumbing Systems: Double Check Valves (DCV) are used in various plumbing systems. They rely on two sets of shut-off valves that can open and close as needed to prevent backflow effectively.

A backflow preventer is a device that allows water to flow in only one direction, preventing contaminated water from flowing backward into your home’s clean water supply. It protects your drinking water from contaminants like bacteria, sediments, and chemicals that can enter through cross-connections with irrigation systems, fire sprinklers, private wells, boilers, hose bibs, or swimming pools.
Backflow preventers should be tested once per year. We recommend checking with local codes or your water utility company to make sure. Regular testing helps ensure the device is functioning properly and keeps your water supply safe.
A routine backflow test typically takes less than an hour. Installation time depends on the device and whether piping modifications are needed, usually a few hours to a full day. In most cases, water service is briefly interrupted during installation or tests; our technicians will coordinate timing to minimize disruption.
We assess your system and install the right type for your pressure and risk profile. We typically install Atmospheric Vacuum Breakers (AVB) for low-pressure systems, Pressure Vacuum Breakers (PVB) for higher-pressure systems with multiple check valves, and Double Check Valves (DCV) for general plumbing applications.
