Commercial Plumbing
O'Connor Plumbing delivers comprehensive commercial plumbing solutions including diagnostics, repairs, and installations. Our technicians handle complex systems in office buildings, retail spaces, and industrial facilities. With specialized equipment and 70+ years of experience, we ensure minimal downtime while maintaining code compliance and system efficiency.
Hydro Jetting
Our hydro jetting service uses high-pressure water streams to clear stubborn clogs and buildup in sewer lines. This non-invasive method effectively removes grease, scale, and debris from commercial piping systems. Technicians utilize advanced equipment to restore optimal drainage without damaging existing infrastructure.
Sewer Lining
Sewer and pipe lining services offer trenchless solutions for damaged underground pipes. Using camera diagnostics and cured-in-place pipe technology, we repair cracks and leaks without excavation. This minimizes property disruption while extending the lifespan of commercial plumbing systems.
Water Heaters
We specialize in commercial water heater installation, maintenance, and repair for businesses. Our services cover traditional tank systems and energy-efficient models. Technicians ensure proper sizing, venting, and temperature regulation to maintain consistent hot water supply for commercial operations.
Drain Maintenance
Regular drain maintenance prevents clogs and backups in commercial properties. Our technicians perform inspections, cleaning, and repairs using specialized tools. We address issues in kitchen drains, restroom facilities, and industrial waste lines to maintain proper flow and prevent costly emergencies.

Horrible. Gave an estimate of $1,500 to replace a drop-in kitchen sink; we already had the sink and faucet. They came up with all sorts of reasons to replace and upgrade every possible thing related to the plumbing we've never had an issue with. Never got the estimate to replace the septic pump after two visits (service charges of course) because they wanted to charge a minimum of $450 to run a camera through the line first, etc. or they couldn't warranty the pump.

We've used O'Connor plumbing three times now. They replaced all the drip lines to our toilets, installed three toilets, and repaired the drip line to our refrigerator. They've done a very good job each time! Will definitely be calling O'Connor again for any plumbing work in the future.

HUGE thanks to O'Connor and especially Ethan and Clayton, who replaced our toilet, the water heater, and redid the shower all while fielding the questions of my two kids, worked around the curiosity of two cats AND the dog! They were fast and efficient, they were friendly, and now a couple weeks later everything continues to work perfectly!

If you want responsive, timely, professional plumbers, this is the company for you! Ethan and Clayton were professional, timely, and did a super clean install! They were able to solve an issue that I've been dealing with for over a year and had other companies unable to fix. I will 100% be using them for any future issues I have as well as recommending them to anyone I know who is having trouble or wants to upgrade. Best plumbers around!
