Backflow Prevention Devices

To prevent the backflow of water from your home or business to your clean water source, a Backflow Preventer is installed.
 
The Backflow Preventer uses a system of check valves:  the valves are open when the flow of water is flowing in the right direction, from the clean water source to your home or business.

If the flow of water is reversed, the check valve engages and stops the reverse flow of water, preventing any contaminates from entering the fresh water source.

50 Years.png

A real-world example of Backflow: in recent years, there have been two events that not only have stopped the flow of the Mississippi River, but have caused the River to reverse directions and flow backwards:  2005 after Hurricane Katrina and 2012 after Hurricane Isaac.

Mississippi

Your Home or Business

Source(s)

Streams, lakes, and smaller rivers (fresh water)

City or well water (fresh water)

Transportation

Combination of Source(s) into one large body of water
From the Source(s) to smaller water pipes

Water Output

Into the Gulf of Mexico (salt water)
Water for use for faucets, toilets, etc (eventually grey water)

Now, if either the flow of the Mississippi River or your home or business is reversed, there is the potential to have salt water or grey water moving toward your fresh water source, tainting your water source.  The flow of water needs to remain going in a one-way direction, but there can be disruptions in the water pressure that cause the water to reverse flow, or backflow.  With the Mississippi, the disruptions are catastrophic events; with your home or business, the disruptions in water pressure can be caused by a break in your water main or by the local fire department putting out a fire.

Backflow Testing Frequently Asked Questions

Why Do I Need to Have a Backflow Test?

If you have a backflow device installed on your property, you are required to have it tested. Backflow testing is an important part of maintaining a safe and clean water supply, and it helps ensure that your property is in compliance with all state and local regulations. 

 

The drinking water supply can become contaminated if backflow occurs.  A backflow preventer is the last line of defense against contamination of your drinking water.

What are Backflow Preventers?

Backflow preventers are devices that are installed in plumbing systems that protect your drinking water from contamination. Backflow can happen when there is a sudden change in the water pressure, such as when a fire hydrant is turned on or when a water main breaks. This can cause dirty water to flow back into the clean water system.

What is Backflow Testing?

Several Northern Nevada municipalities require annual testing of the backflow preventer device. Backflow testing is the process of checking a backflow preventer to ensure it is functioning properly. A backflow preventer is a device that is installed in your plumbing system to protect your drinking water from contamination. Backflow can happen when there is a sudden change in the water pressure, such as when a fire hydrant is turned on or when a water main breaks. This can cause contaminated water to flow back into the clean water supply.

Does an Irrigation System Have a Backflow Device?

Yes, an irrigation system is required to have a backflow device if it is connected to the public water systems.

 

An irrigation backflow device is a mechanical device that is installed in an irrigation system to protect the water supply from contamination. Backflow devices allow water to flow in one direction only, preventing contaminated water from flowing back into the public water supply.

 

All irrigation systems in Nevada are required to have a backflow device, and these devices must be tested annually by a certified back

Are There Different Types of Backflow Prevention Devices?

There are several types of backflow preventers. The most common type is the double check valve backflow preventer (DC). A DC has two shut-off valves and a check valve. The two shut-off valves allow maintenance on the device without shutting off the water to your entire property. The check valve prevents contaminated water from flowing back into your clean water supply.

 

Another type of backflow preventer is the reduced pressure principle backflow preventer (RP). An RP has two shut-off valves, a check valve, and a relief valve. The RP is designed to protect against higher-pressure backflow.

 

The last type of backflow preventer is the double check detector assembly backflow preventer (DCDA). A DCDA is similar to a DC, but it also has a low-pressure alarm and a test port. The test port allows for the backflow preventer to be tested without shutting off the water to your property.

What is Done During the Backflow Testing Process?

The backflow testing process is important to ensure that your water is safe from contaminants. This process involves checking the pressure of the water flowing into your home, as well as the direction of the flow. Hoffman Plumbing is certified to perform this test and can give you peace of mind that your water is safe.
