Backflow Testing


Backflow is the reversal of directional flow in any pipeline system due to a change in pressure.  Backflow is dangerous because it causes our drinkable water supply to become contaminated.

A Backflow Preventer must be installed for any irrigation system connected to a municipal water source (i.e. city or county water). Backflow Preventers are also mandatory for irrigation systems connected to a well that is also used for drinking purposes. At JB Lawn Sprinklers, we have experienced technicians to install and test backflow preventers.

Testing must be done annually to ensure the Backflow Prevention Device is working properly. JB Lawn Sprinklers has NCRWA Certified Backflow Testers on Staff that can conduct your test using a calibrated test kit. All water downstream of the device needs be shut off while the test is being conducted, so it is important to have an experienced professional providing testing.
