Our Residential Backflow Prevention Installation Services

A residential backflow preventer allows water to flow exclusively in one direction, keeping potable water free from contamination. We oversee the installation process, from selecting the backflow prevention device to performing tests and scheduled maintenance.

Residential Backflow Prevention Device Selection

Several types of backflow preventers exist with different applications. We determine the suitability of your residential water backflow preventer based on your water or sewer system’s water pressure, hazard degree, application, and plumbing codes in your area. There are specific residential backflow preventers for lawn irrigation systems, fire sprinklers, potable water, sewers, and drain lines. Every home has distinct backflow preventer devices for pools, faucets with hose attachments, garbage disposals, toilets, and dishwashers. 

Residential Backflow Preventer Installation Services

We recommend having a qualified professional install your backflow preventer to protect your water supply. Improper installations increase the risk of contamination and fines for non-compliance with plumbing codes. Our team of experts can handle all residential backflow prevention installation solutions, from creating air gaps on pool lines to vacuum breakers on hose bibs and double-check valve assembly (DCVA) and the pressure vacuum breaker assembly (PVBA) for irrigation systems. We ensure every backflow preventer device functions well before completing the installation process.

Backflow Prevention Inspections for Residential Homes

Before a residential backflow preventer installation, we conduct comprehensive inspections of your plumbing system to locate ideal installation sites. We conduct visual inspections using top-grade video cameras of your plumbing system and the residential water backflow preventer for any damages or defects. Our in-house plumbers also perform functionality tests to verify the device performance and compliance checks to ensure they comply with state and local plumbing codes and regulations.

Backflow Preventer Residential System Tests

Once the installation is over, we perform comprehensive tests to ascertain the functioning of the backflow preventer device. We use industry-grade testing equipment to conduct our assessments and analysis. Our tests begin by attaching a test kit to the backflow device to capture water samples. We then test the sample to ascertain no backflow is present. Our plumbers adjust and repair the devices if the tests show negative results. We ensure all our processes comply with plumbing codes throughout the installation process.

Frequently Asked Questions

Is the Febco residential backflow preventer 3/4 the best at preventing backflows?

The Febco residential backflow preventer 3/4 is the most common backflow prevention device in homes due to its durability, high-quality materials, and industry standards compliance. However, professional plumbers choose a device suitable for your plumbing system, pressure needs, and application, which may not always be the Febco device.

Both state and local plumbing regulations and codes require homeowners to install backflow preventers on fire sprinkler systems to prevent stagnant water on the fire lines from contaminating treated, potable water in the city or municipal water supply. Water from the hydrant that flows into the fire sprinkler system is untreated. It should never mix with water from the potable main line.

The pressure vacuum breaker (PVB), reduced pressure zone (RPZ), and double check assembly (DCA) are the most common types of backflow preventers installed in irrigation systems. They are all installed after the isolation valve in the water system. Backflow preventers are especially crucial when using fertilizer through a drip in a residential irrigation system.

The residential backflow prevention installation can cost anywhere between $105 and $1400. The average cost of installing a regular backflow is $325. Prices vary depending on the backflow preventer type, the number of devices needing installation, and the plumbers required to provide the service. Some contractors charge on an hourly basis while others have a standard time for the installation.
