Lawn Sprinkler Winterization

Post Date:10/11/2019

October 11, 2019 -- Bartlett's Cross Connection Control Program is designed to safeguard public health by monitoring and regulating any actual or potential connections between the public water supply and a potential contamination/pollution source. One example of a cross connection is lawn irrigation systems, which require a backflow preventer be in place in order to keep Bartlett's drinking water safe. 

Lawn sprinkler systems should be getting winterized soon. If your sprinkler system's backflow preventer is located outdoors, remember to either blow it out or remove and store it someplace warm for the winter. You may cover it with a blanket, towels or something similar temporarily. Insulation and/or heat tape may also be used, but would be insufficient protection for the winter. Allowing it to freeze is a costly mistake. 

Once removed, remember where you stored your backflow preventer. You will need to give it to your lawn irrigation contractor or plumber next spring to re-install it. Plumbing Code requires that your backflow preventer be tested upon re-installation every season by a certified tester. Test results are then submitted online at by your tester.

Bartlett Public Works asks for your cooperation with its Cross Connection Control Program, its enforcement and any requests for information that come from contractor Aqua Backflow or PW staff.
