Jo-Nan Plumbing Backflow Testing Gives Chicago Area Residents 30% Off RPZ Testing.

Jo-Nan Plumbing Backflow Testing is offering 30% off lawn sprinkler RPZ testing, when a neighbor is referred. “Everyone in Illinois is required to get RPZ testing, so we thought a 30% referral discount would encourage residents to get it done now before their lawn sprinklers are in heavy use,” said John Lemeister, owner of Jo-Nan Plumbing Backflow Testing.

As spring approaches many homeowners turn their attention to the yard preparing to bring it back to life. Sodding, seeding and planting shrubs, trees and flowers require outside spigots and lawn sprinklers to be primed. In preparation, Illinois residents will need to have their lawn sprinklers RPZ tested.

The Illinois Plumbing Code requires that a reduced pressure backflow device, (RPZ) be installed on all lawn sprinkler systems to protect the clean water supply. These RPZ valves are required by the state to be tested annually to prevent the contamination of the public water supply by faulty valves.

RPZ testing can only be done by a licensed plumber with a valid Cross Contamination Control Device Inspector, (CCDI) certification. “Only a plumbing contractor with the proper requirements can legally test a backflow device in the state of Illinois and Chicago. Don’t be fooled by some companies who charge for the price of a licensed plumber but are sending out unlicensed people,” warned John.

Jo-Nan Plumbing Backflow Testing will make sure a homeowner’s backflow device is compliant with local and Illinois state laws. They are licensed and experienced to install backflow prevention devices, perform RPZ testing, repair, clean and service backflow prevention valves.
