Standard Backflow Test

For residential customers who require a single test of their backflow assembly. Once scheduled, we'll come to your residence to test your assembly and submit all required paperwork to your water district as well as email you a copy of the report. It is not required you be present when we test your assembly but we will leave a door hanger advising you when the test has been completed.



Don't let freezing temperatures ruin your costly investment. Flowcheck is one of a handful of companies who actually blow out your entire system with an industrial size air compressor. For this reason, we guarantee against freezing! Due to cost of running our equipment, we require all winterizations to be scheduled prior to November 10 each year.


Spring Startup

Winter can be especially hard on irrigation systems. We'll make sure your system is in top working order before the heat of summer hits. Service includes opening gate valves, assessing condition of backflow preventer, checking each valve and replacing any broken or worn out heads and nozzles. We even throw in up to $20 worth of parts - FREE - to make sure your system is ready to go for watering season!
