Irrigation season is when many Federal Way property owners remember their backflow assemblies, and cold weather near the I-5/320th Street interchange is when exposed assemblies need protection. Greener Cleaner tests and services assemblies year-round.
Failed backflow assemblies usually need a repair or rebuild before they can pass. Our licensed, bonded, and insured Federal Way plumbers (Plumbing Lic. GREENCH741OS, HVAC Lic. GREENCH769NG) can service most common assemblies, so you don’t need a separate contractor for the fix.
Testing, repair, and paperwork handled together for Federal Way property owners.
The most common trigger is a notice from your water provider that testing is due. Other signs include an assembly that leaks or discharges water, a device damaged by freezing, or a new irrigation system or commercial build-out that requires an assembly. In Federal Way, where a mix of single-family homes built from the 1970s through today is common, properties near the I-5/320th Street interchange range from older homes with irrigation systems to commercial spaces with multiple assemblies.
A typical test measures how the assembly’s check valves and relief valve perform under controlled pressure, and the results are recorded on a report submitted to your water provider. If the assembly fails, it usually needs a repair, such as replacing worn seals or valve parts, and a retest. For Federal Way properties near Dash Point, we can often handle the repair and retest in the same visit. If a part has to be ordered, we’ll tell you how long the assembly can stay in service and what your provider expects in the meantime.
Commercial properties in Federal Way, including restaurants, offices, and multi-tenant buildings near Steel Lake, often have several assemblies on different lines. We can inventory them, schedule all the tests together, and keep a record of results, which simplifies compliance for property managers.
For property managers and business owners with multiple assemblies, consistency matters. We can set up a recurring schedule for your Federal Way properties, so every assembly is tested, documented, and repaired on time. One schedule, one point of contact, and one set of records is far easier than managing each assembly on its own calendar.
