When property owners need a backflow plumber in Greenville, SC, they choose Tuck & Howell. Located in Duncan, we have provided backflow services in the Greater Greenville area since 1969. Depend on our plumbers for inspections, new installations, replacements, maintenance, repairs, and much more.

Expert Backflow Services for Greenville Properties

Our backflow prevention services provide property owners with peace of mind. Without prevention, many properties are at risk of dangerous substances entering their water supplies.

Backflow problems can manifest in many different ways, so monitor for issues with your:
  • Dishwasher
  • Swimming pool
  • Drains and toilets
  • Irrigation systems
  • Garbage disposal
  • Fixtures with attached hoses

Licensed and Experienced Backflow Specialists

All the backflow specialists at Tuck & Howell are licensed plumbers, as required by South Carolina law. Our team holds many backflow prevention-related certifications. We also train our plumbers to ensure they are current with the latest codes and technologies.

Prompt Service for Backflow Emergencies

Tuck & Howell has plumbers on call for emergencies that cannot wait until the next business day. We’re here for you whether it’s the middle of the night, a weekend, or the holidays. For all standard appointments, we strive to deliver same-day service to all customers.

What Is a Backflow?

Wastewater drains from your home into a sewer line or a septic system. There are two types of wastewater: gray and black. Water from sinks, showers, and washing machines is an example of graywater. Water from toilets and, occasionally, dishwashers is an example of blackwater. Backflow occurs when any contaminated water flows backward into the clean water supply. A backflow preventer is often the best solution if your system is susceptible to it.

24/7 Emergency Services Available!

The Causes of Backflow

The most common cause of backflow is a sudden drop in water pressure. This can occur due to a ruptured water main, backpressure from a pump, or unusually high water demand. Graywater or, even worse, blackwater, can contaminate drinking water without a preventer.

Potential contaminants include:
  • Sewage
  • Chemicals
  • Pathogens
  • Industrial waste

Backflow Prevention and System Testing

We can perform a comprehensive inspection and assessment if you don’t currently have a backflow preventer. If you need a preventer, we’ll help you choose the ideal solution for your property. We offer a wide range of high-quality backflow prevention systems. Backflow preventers essentially operate as one-way gates. Water can move in one direction, but it can’t flow back even if there’s a sudden loss of pressure or another issue.

Tuck & Howell also recommends regular backflow testing services. Commercial properties often require annual testing and certification, while residential properties should be tested every two to three years. Our team will ensure that your system is functioning properly and is compliant with all local regulations. When needed, our backflow services extend to correcting wear and tear, including cleaning and calibrating equipment and replacing parts.

Backflow Preventer Installation and Repair

You need a backflow preventer if you have drains flowing in the wrong direction. If you already have one, you’re likely experiencing problems with your current system. Our team performs routine inspections and maintenance that help avoid repairs. We complete all kinds of repairs, including full rebuilds, to adhere to all South Carolina building codes and manufacturer warranty requirements. Our company also handles new installations and replacements.

Adam was wonderful and came to give us an estimate to run a gas line to install a natural gas stove. We thought the price is very fair and Adam will be doing the gas line installation. Tuck & Howell Company is very professional and are quick with service. I recommend them.

We tried to change out a thermostat on our own but the heat wouldn’t come on afterwards. After trying everything we could think of we called Tuck & Howell and they sent 2 technicians, Tony and Tom, out the next day. They wore booties to protect the floor, and were very professional. They quickly figured out the problem and got our heat back up and running in no time. I highly recommend Tuck and Howell and if you are lucky you’ll get Tony and Tom.

UPDATE 1/29/26–With the cold weather the same issue I had a month ago came back and the house was 62° when I woke up. With potential snow this weekend I couldn’t wait. Tuck and Howell were able to get a tech to me that day AND work with my work schedule. The tech called before heading my way to let me know when he would arrive which allowed me time to walk the dogs. They also text a photo of your tech so you know who to expect which I really appreciated. Tyler went straight to work and while there were no major issues he let me know everything that he did. He was even kind enough to call my husband to relay everything directly to him as well. There is a reason this company has the number of glowing reviews they do. I know we won’t hesitate to call Tuck and Howell when we need our furnace or AC serviced, repaired or replaced. 12/15/25 While I was able to troubleshoot the issue I was having, I will say that the quick response to my online inquiry was awesome. I also received a phone call from Stacy following up. Having a business that is this responsive to customers and potential customers is rare and wonderful. I will absolutely be calling in the future to give my business to Tuck & Howell. Thank you for having excellent customer service, care and support.

It was a very positive and interesting experience. Technicians dispatched to my location were very professional and did an excellent job. I work at night and went to get something to eat and let them do the various tasks. Went to work with peace of mind knowing the job was to my satisfaction! Comfortable temperature was reached shortly after I got off shift and system had done its job. Again thanks to the 2 technicians for a job well !! Everything from start to finish, was a well orchestrated 'Process'. Thanks to everyone involved. Ready to deal with this predicted frozen weather conditions.

Chandler and BJ arrived at the promised time and were courteous and knowledgeable. They explained so that I understood the problems with my HVAC system and gave me a reasonable quote for replacement. The installation was scheduled for the next day. I was treated as a valued customer. Hunter Longshore, Tom, and Dennis did the installation for me and arrived early, went straight to work and completed the job in record time. They cleaned up the work area and hauled away the old unit and its parts. Soon our home was warm again and we were very grateful customers. I recommend Tuck and Howell to all.
