4 Backflow Testing Methods (And You Should Get One Now!)

Have you noticed an unusual smell or taste in your drinking water? If so, you must get Kansas backflow testing for your residential or commercial properties.

An unusual smell or taste in your drinking water is an alarming sign that contaminated water is mixing into your drinking water supply. If left unchecked, it can cause serious health issues to the residents in the region.

 


But how do you perform backflow testing? Let’s learn about the 4 methods used for backflow testing.

Methods of Backflow Testing

  • Double Check Valve Assembly Testing

If you have a residential irrigation system, you can get backflow testing using this method. The test is usually implemented for low- to moderate-hazard devices.

The test is simple. The technician checks the water pressure in each internal valve. It is observed that the internal valve must maintain a pressure of 1.0 PSID during reverse flow. If it does, the system is working fine. However, if it doesn’t, more thorough testing is required.

  • Reduced Pressure Zone Testing

This method is used for commercial properties. If the property has large commercial boilers, medical equipment, or any other high-hazard system, the technician will perform this test.

The technician will use a multi-hose valve check. The technician will check internal valve 1, the relief valve, and internal valve 2. The internal valve 1 must maintain a pressure drop of 2.0 PSID. The technician then releases the relief valve to ensure the excess water is released efficiently. The technician builds up backpressure on the internal valve 2 to check that the valve is 100% airtight.

  • Pressure Vacuum Breaker Testing

This backflow testing method is used for automated water sprinklers. The test is done in 2 parts.

First, the technician will drop the internal water pressure and observe when the air floats open. The standard is 1.0 PSI, when the sprinkler should stop siphoning.

Second, the technician will check the internal valve. The valve is pressurized to confirm it stays tight even if the pressure drops to 1.0 PSI.

  • Air Gap Visual Inspection Testing

It is a non-mechanical testing method usually used for storage tanks, commercial basins, and faucets. This testing is a visual verification that the lowest opening of the water supply and the receiving vessel has a single unobstructed vertical distance between them running through the open atmosphere.

 

The distance must be double the diameter of the supply pipe. If it isn’t, the technician will suggest the right corrective action to ensure there is no backflow of water.
