Backflow test cocks are sprinkler system attachments that are designed to assess the effectiveness of a backflow prevention device. These devices are installed in a variety of plumbing systems to prevent the reverse flow of water, which could allow contaminants into a water supply. You can order a backflow test valve for your sprinkler systems online at Sprinkler Warehouse.
Backflow units should be tested about once a year. During this test, a technician attaches a testing device to each test cock in sequence to verify that the backflow prevention assembly is maintaining adequate pressure to prevent backflow. A successful test helps ensure that water is only flowing in the intended direction, without backflow risk. If there are leaks, pressure drops, or other irregularities in the readings, it indicates that the device may not be providing sufficient backflow protection.
Backflow Test Cock FAQs
Why do I need backflow testing?
Backflow testing is essential for sprinkler systems that connect directly to a potable water supply. Without a backflow preventer test port, your water supply could unknowingly become contaminated by your sprinkler system.
Can I perform a backflow test on my own?
Oftentimes only licensed or certified professionals can conduct backflow testing and repairs. Backflow testing requires specialized training, equipment, and certification, as it involves protecting the public water supply from contamination.
What should I do if my backflow test fails?
If your backflow test fails, it means that your backflow prevention device isn’t protecting your water supply. Your certified tester should provide a detailed report explaining why the device failed. Review this report and schedule repairs promptly, as failing to address the issue could put your potable water supply at risk.
