Scheduled cleaning of grease, kitchen, and floor drain systems before they back up.

Planned Maintenance Program FAQ
What size facility makes a maintenance plan worthwhile?
Anything with backflow assemblies, commercial water heaters, or grease interceptors usually pays for the plan in avoided breakdowns and on-time compliance.
Can one plan cover multiple buildings?
Yes. We run multi-site programs with consistent crews so the same technicians know every property in the portfolio.
How is the plan priced?
Flat annual pricing based on the asset list and visit frequency, with any additional repair work quoted separately or billed time and material if you prefer.

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.
