Summarized from City of Englewood's published program information (source), checked October 2026. The notice from your water provider always has the final word on your due date.
Aug. 15 comes fast
Englewood sends notices to commercial and multifamily customers when testing is due, but the deadline is the same for everyone: Aug. 15. If you manage a building with irrigation, fire, boiler, or pool connections, schedule the tests in late spring or early summer so there's time for a repair and retest before the date.
Bought or leased a building?
Englewood asks owners to email its backflow team after buying or leasing a commercial or multifamily property, adding a cross-connection, or changing how the building uses water, such as new irrigation, boilers, or water storage. If a repair turns up, we'll confirm what Englewood requires for that work before we start.
What we do on a Englewood backflow test
- Confirm the assembly type, size, and serial number against your provider's records
- Test every check valve and relief valve with a differential pressure gauge calibrated October 2026 and traceable to NIST
- Tag the assembly with the service date, our business information, and the tester's certification number
- File the completed report the way City of Englewood requires
- Send you a copy of the report, with photos
If the assembly fails
Most failures come down to a dirty or worn check valve, a tired relief valve, or a split rubber part. Those get cleaned or rebuilt and retested, usually in the same visit, after you approve the price. If the body itself is cracked, usually from a missed winterization, the assembly has to be replaced. Replacing an assembly is installation work, which in Colorado needs a licensed plumber; we'll tell you exactly what's needed and do the retest once it's in.
Before we come out
- Have the notice from your water provider handy, or send a photo of it when you book
- Tell us where the assembly is, and leave any gate unlocked or the mechanical room open
- For sprinkler assemblies, the water needs to be on. If the system is still winterized, we can do the spring startup and the test in one visit.
