Commercial plumbing differs from residential in scale and consequences. Drains are bigger, usage is heavier and a stoppage can close a kitchen or a restroom for the day. We work with property managers, restaurant owners and small business operators who need clear answers and quick service.
Common commercial plumbing calls
Drain stoppages
Main lines and floor drains that back up under heavy use.
Grease traps and interceptors
Cleaning and servicing so kitchens stay compliant and flowing.
Backflow testing
Annual testing of devices that protect the water supply.
Leak searches
Pinpointing hidden leaks across larger runs.
Storm drains
Clearing catch basins and drains that flood lots and loading areas.
Restroom plumbing
Toilets, urinals, sinks and flush valves.
Restaurants and food service
Kitchens are hard on drains. Grease, food solids and heavy water use build up quickly, and a grease trap that is overdue can back up the whole kitchen. We service traps and clear the lines behind them, and our hydro jetting page explains how high-pressure water clears the grease coating that snaking leaves behind.
Monterey Park has a strong food scene, with many restaurants along Garvey Avenue, Atlantic Boulevard and Garfield Avenue. Food businesses should ask the City or the county health agency about grease trap and interceptor rules, since requirements depend on the type of operation.

Backflow prevention testing
A backflow preventer stops used or contaminated water from flowing backward into the drinking water supply. Many commercial properties are required to test their devices on a schedule. Requirements and who is certified to test come from the water utility, so confirm with the City's Water Division what applies to your property.
We explain what the test involves and how to keep the paperwork organized, and we repair or replace devices that fail.
| Problem | Likely cause | What we do |
|---|---|---|
| Floor drain overflow | Blocked branch or main | Clear the line and inspect. |
| Slow kitchen drains | Grease buildup | Service trap and jet the line. |
| Wet ceiling tiles below a restroom | Supply or drain leak | Locate and repair. |
| Standing water in a lot | Clogged storm drain or catch basin | Clear and flush. |
| Failed backflow test | Worn internal parts | Repair or replace the device. |
Safety steps when a drain or pipe fails
- Keep staff and customers away from standing water, especially near outlets, kitchen equipment and walk-in coolers.
- Do not touch sewage with bare hands, and wash thoroughly after any contact.
- Mark wet floors and block off the area to prevent slips.
- Shut off equipment that sits in or near the water if you can do it safely.
- Photograph the damage and record the time, for your insurer and your records.
Multi-unit and mixed-use buildings
Monterey Park has apartment and condominium buildings and newer mixed-use buildings with shops below and homes above. In these, shared stacks and risers mean a problem in one unit can affect others. We work with property managers to isolate sections, document findings and keep tenants informed.
Working around your business
We schedule around opening hours when we can, and when an emergency can't wait, the 24/7 line answers. Tell us when you call who can authorize work, where the shutoffs are and whether access is limited after hours.
What affects the cost of commercial plumbing
Cost factors we explain before work starts
Commercial jobs are priced by scope and hours, with after-hours work and compliance paperwork as the usual add-ons.
Commercial property and business interruption policies differ widely. Document the failure with photos and invoices, and ask your insurer or broker what is covered before repairs.
Tell us the property type and who can authorize work, then call (626) 898-6169.
