Full-Service Commercial Plumbing for Hillsborough County Businesses
Since 1969, we’ve been the commercial plumber Tampa businesses call when the job has to be done right the first time. As a family-owned operation now in its third generation, Johnny Doan Plumbing serves restaurants, office buildings, retail centers, and commercial properties throughout Hillsborough County. Our commercial work covers everything from routine maintenance and diagnostics to full-scale repiping, sewer replacement, and 24/7 emergency response.
Commercial plumbing systems run under higher daily demand and stricter code requirements than residential systems. Tampa’s building stock adds its own complications: aging cast iron drain lines in older structures, hard water mineral buildup that accelerates corrosion, and storm-season drainage stress that keeps property managers on edge. We’ve been working through those conditions for over five decades.

Commercial Plumbing Services We Provide
Our commercial service menu covers the full scope of what Tampa-area businesses and property managers typically need, performed by licensed, insured technicians.
Drain, Sewer and Pipe Services We handle hydro jetting, sewer camera inspections, trenchless sewer replacement, drain installation and replacement, pipe repair, sewer repair, and grease trap cleaning. Grease trap service is a recurring compliance requirement for food service operations in Tampa. A clogged trap can trigger health department violations and force an operational shutdown.
Backflow Prevention Commercial properties in Tampa must meet City of Tampa and Hillsborough County utilities requirements for backflow prevention, including annual testing and certification submission. We install, test, and certify backflow prevention devices to help your property stay in compliance.
Water Heater and Supply Line Service We install and replace commercial water heaters and address the hard water mineral buildup that shortens equipment life in Hillsborough County. Water purification and water softener systems are also available for commercial applications.
Emergency and Specialty Services Sump pump installation and repair, storm drain cleaning, water line repair and installation, and full emergency plumbing response are all available, particularly relevant during Florida’s storm season, when commercial drainage systems face their heaviest load.
Tampa Commercial Plumbing Conditions We Know Well
A meaningful share of Tampa’s commercial building stock went up between the 1960s and 1980s with galvanized supply lines and cast iron drain pipes that weren’t designed for current usage volumes. Tree root intrusion is an ongoing concern for properties with clay or cast iron infrastructure, given Florida’s year-round growing season. We’ve resolved both problems for clients other contractors couldn’t help, using sewer cameras and hydro jetting equipment to find what’s actually happening before recommending a solution.
Commercial plumbing work in the Tampa area requires permits pulled through the appropriate local jurisdiction: either the City of Tampa or Hillsborough County. It must also comply with Florida plumbing code, health department requirements, and ADA fixture regulations. Our team stays current with local codes and permitting, which helps keep projects moving without unexpected delays or costly corrections.
Why Tampa Businesses Have Trusted Us Since 1969
Our track record with commercial clients is documented, not just described. We’ve maintained the plumbing systems at Plummers’ Family Restaurant for over 35 years. We’re a listed installer for Home Depot plumbing projects, which requires meeting national retailer standards for quality and accountability. Across more than 1,000 customer reviews, we hold a 4.9-star rating, with clients consistently noting punctuality, clear communication, and our ability to resolve long-standing problems.
Pricing is flat rate with no hidden fees. We explain the scope of work before anything begins, so there are no surprises when the invoice arrives. Free estimates are available for commercial projects, financing options are available for larger jobs, and discounts apply for seniors, veterans, and first-time customers.
Commercial Property Types We Serve
We work with a wide range of commercial clients across the Tampa area: restaurants and food service operations, office buildings, retail centers, multi-unit residential properties, medical and dental facilities, hotels, fitness centers, and property management portfolios. Property managers in particular benefit from working with a contractor who can coordinate around tenant schedules, document completed work, and respond to emergencies without business-hours limitations.
24/7 Emergency Commercial Plumbing in Tampa
Burst supply lines, main sewer backups, water heater failures, backflow device failures, and major drain blockages don’t follow a schedule. For a commercial operation, plumbing downtime means revenue loss, health code risk, and direct impact on tenants or customers. We offer 24/7 emergency service because that’s when it matters most. Our technicians arrive prepared to diagnose and address the problem, not just assess it.
Serving Tampa and Greater Hillsborough County
Our commercial plumbing service area covers Tampa and the surrounding Hillsborough County communities, with a broader footprint extending across Central Florida, including Hillsborough, Polk, Pinellas, and Pasco counties.

"Hands down the best plumber in town"
I've had problems as long as I've lived in this house - I've made calls no less than 3 times this year for backups with my plumbing and it turns out a tree root took out my plumbing and the guys from Johnny Doan Plumbing were finally able to find the problem and resolve it. I've had 3 other plumbers out here for this same problem - and none of them were able to fix it properly, so every other month, when I flushed the toilet, it would back up - and never knew why it kept happening. Glad to know there are pros that know what they are doing - hands down the best plumber in town.

"They came out on time and got it done"

I would recommend them, straight up honest at pretty reasonable price. Thanks!

"The most professional plumber that I have dealt with"
My water heater wasn’t producing enough hot water. I was considering getting a tankless electrical water heater.
They came out and examined my heater. He determined that it had been installed incorrectly. I thought I needed a new heater but I didn’t. It was a very simple fix and he saved me a lot of headache and money. This is the most professional plumber that I have dealt with and I highly recommend this company.
- Satisfied Customer
"High level of knowledge in plumbing"
We had our kitchen remodeled by Home Depot and they subcontracted to Johnny Doan Plumbing and they did such a good job with the plumbing work that we called them back to provide a quote on several plumbing projects around our 1979 built house. When the guy came out to review the work to be performed, he was very professional and quickly provided a fair estimate on the same day. The guys that came out to do the work called ahead to let us know they were coming and they were both professional and courteous. The work they performed was high quality and showed their high level of knowledge in plumbing. I have to call out Tucker, Austin, and Kyle for the great work they did for us. I would highly recommend Johnny Doan Plumbing.

"He truly cares about his work and his customers"
Jimmy came out to check out my water heater. He explained everything very thoroughly and clearly so that I could understand. This is a very professional company. They sent a professional to come and fix my issue for a very good price. The other companies didn’t even know what the issue was. I had spoken to 4 other plumbers before him and I highly recommend working with Johnny Doan Plumbing. He truly cares about his work and his customers.
- Sean H.
"I had a lot of work for them to do and they did it all perfectly"
These guys did a great job. I had a lot of work for them to do and they did it all perfectly. They cleaned up all their debris and trash and took it away, too. Will definitely hire them again.
