What Should Your Maintenance Plan Cover?
Typical items for a office building
Inspect 4 restrooms: flush valves, faucets, carriers
Catches running fixtures and leaks that waste water and damage finishes.
Flush and inspect 1 water heater
Sediment removal extends heater life and prevents surprise no-hot-water calls.
Annual backflow test and report
Required by your water authority — missed tests can mean shutoff notices.
Exercise shutoff valves and check PRVs
Valves that turn when you need them keep a leak from becoming a flood.
