Call us for all your backflow services.


A backflow prevention device is used to protect potable water supplies from contamination or pollution due to backflow.

In water supply systems, water is normally maintained at a significant pressure to enable water to flow from the tap, shower etc. When pressure fails or is reduced, as may happen if a water main bursts, pipes freeze or there is unexpectedly high demand on the water system, then such reduced pressure in the pipe may allow contaminated water from the ground, from storage or from other sources to be drawn up into the system.

What are 3 backflow devices you can install in your home?

Backflow devices can really be instrumental in protecting the water supply in a home. Here are 3 useful backflow devices that can be installed in a home.

  1. The pressure vacuum breaker assembly is classified technically as a backflow prevention device. It protects the potable water in a home, performing similarly to an atmospheric vacuum breaker. This particular device is usually recommended for homes where the valves are downstream. If adequately protected from extreme conditions, they can be better preserved.

  1. The reduced pressure principle valve is used to check valves to prevent water from flowing improperly into the pipes. A check valve bears the resemblance of a disc or a flap. The force of the water pushes it open, permitting water to flow in the correct direction through the pipe. The RPD contains a spring that causes it to open and close when water attempts to make its way through the pipe.

  1. Reduced pressure zone devices contain multiple check valves. The chamber separating the two check valves maintains a certain level of pressure to allow water to be discharged from the drain. A differential pressure relief valve is responsible for managing excessive levels of pressure in the system.

When do you need replacement services?

When living in certain areas, there are conditions that can drastically shorten the life of a backflow system, causing negative changes to your water quality and ultimately limiting the performance of your unit. These issues may indicate that your system needs to be tested. After your system is tested, repairs may need to be made. Backflow valve replacement services may be needed when the backflow valve systems require too many repairs in a relatively short amount of time. If failure begins to occur as a result of changes in the quality of your water, the backflow valve replacement may involve the use of different parts made from sturdier grades of rubber.

What are the benefits of replacement?

Backflow valve replacement services protect the quality of your water and eliminate contaminants from entering your water supply. Replacing the system can also ensure that the water supply is maintained at a consistent level of quality. It can also save a person significant amounts of money by eliminating the need of constant repairs. Back siphonage and back pressure are the two main types of systems that can protect the potable water supply. Backflow prevention systems control the way water enters the system, and eliminates harmful chemicals that could lead to death or chronic illness if one is exposed.
