Backflow Testing & Prevention

At Dogwood Plumbing, we are experts in conducting backflow testing to evaluate the performance of your backflow preventer.



Whether the problem originates inside or outside your home, we are equipped to respond swiftly, ensuring that the water you utilize for drinking, cooking, cleaning, and bathing remains pure and free from pollutants like waste, dirt, and chemicals.

Backflow preventers must be inspected and tested every year. If not, a home or business owner can face heavy fines. Testing must be completed by a licensed professional.

Dogwood Plumbing has experience in backflow preventer testing. The testing process involves opening and closing valves in the backflow system while taking pressure measurements. We’ll also determine if a backflow preventer activates when it’s supposed to.

The steps taken can help identify any abnormal changes in pressure that may warrant repairing or replacing your backflow preventer.

Backflow Explanation

Backflow prevention devices are generally situated just beyond your water meter. They may be housed within a mechanical or riser room and vary in size from half an inch up to twelve inches.

If the devices are double check valves, they are likely installed in a meter box or a concrete vault underground.

On the other hand, if they are reduced pressure zone devices (RPZ), they will be located above ground within an insulated enclosure.

Installed on the customer's side of the water meter, backflow devices are critical for preventing water from reversing into the main water supply.

This is essential to stop contaminants from entering the customer's water system and potentially affecting others downstream.

These devices operate using check valves to block both back pressure and back siphonage. It is mandatory to test these check valves annually to confirm their operational integrity.

What Causes Backflow?

Backflow happens when water reverses its flow and contaminates the clean water supply lines in your home. This can take place at any cross-connection within your plumbing system or externally, such as when a sewer line or water main breaks.

The main reasons for backflow are:

Back Siphonage: This happens when the water pressure in your pipes drops. If the pressure in one section is lower than in others, fluids from areas of higher pressure can surge into the lower pressure area, creating a vacuum effect that pulls water backward.

Back Pressure: Back pressure develops when a pump exerts pressure within the pipe system or when water is influenced by gravity, like when a hose is raised above the ground level. Additionally, a decrease in water pressure due to a surge in demand, a ruptured water main, or a frozen pipe can also trigger backflow.
