Commercial Plumbing Services for St. Catharines Businesses
A commercial property puts far more strain on its plumbing than a home ever does. Higher water use, bigger systems, stricter codes, and a lot more people depending on everything working. Super Drain St. Catharines covers the full range of commercial plumbing, from routine maintenance to major repairs and new installations. Whatever your building needs, our commercial plumbers get it sorted with as little disruption to your operation as possible.
Commercial Drain Cleaning & Hydro Jetting
Grease, food waste, paper, and mineral scale clog commercial drains far faster than residential ones. We clear blocked floor drains, sinks, and main lines using augers and high-pressure hydro jetting that scours the pipe walls clean and restores full flow.

- Blocked floor drains and sinks
- Main line and branch line cleaning
- High-pressure hydro jetting
- Camera inspection to find the cause
Grease Trap & Interceptor Service
Every food service business needs a grease trap that actually works, both to stay onside with local sewer bylaws and to avoid a mess in the kitchen. We install, clean, repair, and correctly size grease traps and interceptors for restaurants, cafes, and commercial kitchens.
- Grease trap installation and sizing
- Cleaning and pump-outs
- Interceptor repair and replacement
- Compliance support for food service
Backflow Prevention & Testing
Many commercial, industrial, and multi-residential properties in Ontario are required to have their backflow preventers tested every year to protect the public water supply.

Our certified testers install, test, repair, and certify backflow devices, then handle the paperwork so you stay compliant.
- Backflow device installation
- Annual testing and certification
- Repair and rebuild of failed devices
