Commercial Plumbing Maintenance Checklist for Redlands Businesses

Monthly Checks

Commercial plumbing handles far more daily use than residential systems, and small problems escalate faster in high-traffic environments. A monthly walkthrough by your facilities manager or building maintenance staff should cover:

• Check all exposed pipe connections and fixtures for drips or corrosion signs
• Test all floor drains to confirm they're clear and draining — pour a bucket of water if necessary
• Check water heater temperature and pressure gauges against normal operating ranges
• Inspect under-sink areas in bathrooms and kitchen/break rooms for any moisture accumulation
• Test shut-off valves by turning them slightly to confirm they're not seized (fully close and reopen a quarter turn)
• Check for any toilet running or flushing problems in all restrooms

Catching small leaks and developing fixture problems monthly keeps minor maintenance costs low. A dripping faucet in a commercial setting running 60 or more hours per week wastes water and adds to utility cost substantially more than the same faucet in a home.

Quarterly Tasks

Every quarter, go deeper on the systems that see the most use:

• Clean all sink aerators and faucet screens — commercial settings accumulate debris faster
• Inspect water heater anode rods and flush tanks to clear sediment accumulation
• Clean any floor drain strainers and p-trap primers in areas where floor drains are infrequently used
• Run water in any infrequently used fixtures (breakrooms, storage area sinks, seasonal restrooms) to keep traps filled and prevent sewer gas intrusion
• Test that all emergency shut-off valves are operable and accessible — not blocked by stored equipment or supplies
• Check water pressure at multiple points in the building; significant variation can indicate developing blockages or supply line issues

For Redlands businesses, the quarterly flush of water heaters is especially important given the hard water. Tank units that serve high-demand commercial applications in the Inland Empire scale faster than residential units.

Annual Professional Service

Once per year, schedule a professional plumbing inspection and maintenance visit that covers what staff walkdowns can't adequately assess:

• Full pipe system inspection including visible runs in utility spaces, accessible ceiling areas, and crawl spaces
• Water heater professional service including full flush, anode rod replacement, and control inspection
• Sewer line camera inspection for restaurants, food service facilities, or any business over 20 years old with legacy pipe
• Pressure test on the main supply system to check for hidden leaks
• Inspection of all flush valves, pressure-assist mechanisms, and commercial toilet components
• Water quality testing if relevant to your business operations

An annual professional inspection also creates documentation that can be valuable for insurance purposes, lease negotiations, and demonstrating due diligence in property management.

Grease Traps (Food Service)

Restaurants, cafes, bakeries, and any food service operation in Redlands must maintain their grease trap (also called a grease interceptor) on a schedule that keeps it functioning properly. Grease traps are required by the City of Redlands and San Bernardino County sewer districts to prevent fats, oils, and grease (FOG) from entering the municipal sewer system and causing blockages.

Grease trap pumping frequency depends on the trap's capacity and the volume of food production. Most commercial kitchens need pumping every one to three months. The "25% rule" is common: pump when the grease and solids layer reaches 25% of the trap's capacity. Waiting longer than this results in grease passing through the trap and into the sewer line — both a code violation and a recipe for a blockage that shuts down operations.

We work with commercial kitchens throughout the Redlands area for grease trap service. Keep service records — Redlands utilities and health inspectors may request them.

Backflow Preventer Testing

California state law and local water district requirements mandate annual testing of backflow prevention devices on commercial properties. Backflow preventers protect the municipal water supply from contamination that could occur if the water pressure drops and water flows backward from a building's system into the public supply.

The annual test must be performed by a licensed backflow tester and the results submitted to the water utility. If you haven't received a notice or aren't sure whether your property has a backflow preventer, check with your water supplier or have us inspect. Failing to comply with annual testing requirements can result in notices, fines, and in extreme cases, water service shutoff.

We perform backflow preventer testing and are registered to submit required documentation to the appropriate Redlands-area water districts.

Documentation and Code Compliance

Keep a maintenance log — either physical or digital — that records every service visit, inspection finding, and repair with dates and who performed the work. This documentation serves multiple purposes: it helps you track patterns (a drain that clogs every six months despite cleaning points to a structural problem), provides evidence of due diligence for insurance purposes, and supports property valuation in sale or lease negotiations.

For businesses in Redlands' older commercial buildings downtown — some of which date to the early 20th century — pipe systems may be significantly aged and worth a comprehensive assessment if one hasn't been done recently. Older cast-iron drain lines and galvanized supply lines in commercial buildings have the same failure modes as their residential counterparts, amplified by higher daily usage.
