Backflow testing and sprinkler plumbing
Backflow testing checks that the backflow preventer on your irrigation system stops sprinkler water from flowing back into drinking water. Many Northern Colorado water providers require a certified test, often annually, and a report filed by the tester. Plumbers also repair freeze-damaged backflow devices and supply lines.
- Typical time
- Under an hour for a test.
- Repair or replace
- Rebuild or replace frozen or failed devices.
Backflow preventers sit above ground on many homes and freeze easily. Draining and blowing out the irrigation system in fall prevents cracked bodies and split lines.
In spring, a cracked backflow or a leaking supply line in the basement is a common first call.
