Every assembly on every property, tested, tagged, and filed with the right water provider, on one schedule and one invoice.
Who we test for
- Property managers and HOAs: common-area irrigation, clubhouses, pools, and building domestic lines
- Apartment and condo buildings
- Offices, retail, and mixed-use buildings
- Restaurants and commercial kitchens
- Churches and schools
- Medical and dental offices
Assemblies we test
- RPZ / RP (reduced pressure zone) on domestic, irrigation, and process lines
- DCVA / DC (double check valve assemblies)
- PVB and SVB (pressure and spill-resistant vacuum breakers) on irrigation
Fire sprinkler backflow assemblies need a separate state fire suppression registration, and several water providers require it. We test domestic, irrigation, and process assemblies.
How it works for a portfolio
- Send us your list of addresses, assemblies, and due dates, or the notices you've received
- We build the schedule around the due dates and group nearby properties
- Each report is filed the way that property's water provider wants it: by email to Denver Water, through Aurora Water's portal, BSI Online for cities like Thornton, Westminster, Broomfield, Northglenn, Englewood, Louisville, and Lafayette, Arvada's SAMS portal, Consolidated Mutual's portal, or the Parker Water and City of Boulder portals
- You get a copy of every report, photos of every assembly, and one consolidated invoice
- Failed assemblies get a written repair quote that fits your approval limits
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.
