    Complete Water Heater Repair & New Installation Services

    Hot water is one of those things you never think about until it stops working. When it does, Paynes Plumbing is ready to get your home back to normal — fast. From new installations and full replacements to repairs and routine maintenance, our team handles every part of keeping your water heater running the way it should.

    We service all major systems, including traditional gas and electric tank units, energy-efficient hybrid (heat pump) models, and modern tankless water heaters. Whether you have a standard 40- or 50-gallon tank, a high-demand 60-gallon (or larger) unit for a busy household, or a whole-home tankless setup, our licensed plumbers have the experience and equipment to install, repair, and maintain it correctly the first time.

    Not sure whether your water heater needs a quick fix, a tune-up, or a full replacement? We’ll take an honest look, walk you through your options, and help you choose what makes the most sense for your home, your budget, and your long-term energy costs.

    Water Heater Repair

    Cold showers, leaks, and strange noises don’t wait for a convenient time — and neither do we. Paynes Plumbing offers fast, reliable water heater repair to get hot water flowing again before a small issue turns into a costly one.

    Common Water Heater Issues

    • No hot water or not enough hot water
    • Leaks around the tank, valves, or fittings
    • Discolored or rusty water
    • Popping, rumbling, or knocking noises
    • Inconsistent or too-hot water
    • Pilot, ignition, or burner problems on gas units
    • Error codes and scale buildup on tankless systems

    We service gas, electric, hybrid, and tankless water heaters for homes and commercial businesses.

    Every repair starts with a clear diagnosis and an upfront price. We’ll let you know honestly whether a repair is the smart move or if replacement will save you more in the long run.

    Repair First, Replace Only When It Makes Sense

    A new water heater is a big investment, and most of the time it isn’t necessary. Our approach is simple: fix what you have whenever we can. Many issues — failed elements, thermostats, valves, ignitors, or sediment buildup — are straightforward repairs that can add years of life to your existing unit at a fraction of the cost of replacement.

    We’ll only recommend a new water heater when repair truly doesn’t make sense — a leaking tank, a unit well past its lifespan, or repair costs climbing close to the price of replacement. You’ll get a straight answer and clear options, so the choice is yours.

    New Water Heater Installation

    When it’s time for a new water heater, the right choice and the right install make all the difference in comfort, efficiency, and how long your system lasts. Paynes Plumbing & Electric handles new installations and full replacements from start to finish, so you get reliable hot water without the guesswork.

    Helping You Choose the Right Unit

    Picking a water heater isn’t one-size-fits-all. We’ll talk through your household’s hot water demand, fuel type, space, and energy goals to recommend the best fit. Our team installs:

    • Gas and electric tank water heaters
    • Hybrid (heat pump) water heaters for major energy savings
    • Tankless water heaters for endless on-demand hot water

    Professional, Code-Compliant Installation

    Every install is done by a licensed plumber and built to local code, including proper venting, gas lines, electrical connections, and safety valves. We’ll also remove your old unit, clean up, and walk you through everything before we leave.

    Water Heater Maintenance

    Routine maintenance is the easiest way to get more years out of your water heater and avoid surprise breakdowns. An annual tune-up keeps everything running safely and efficiently, and gives us a chance to check the T&P valve, thermostat, heating elements, burner and venting (on gas units), and all connections for early signs of wear.

    The Core Maintenance Items

    • Tank flush to remove sediment that causes noise, reduces efficiency, and shortens tank life
    • Anode rod inspection and replacement to prevent corrosion inside the tank, one of the most important and most overlooked steps
    • Tankless descaling and filter cleaning to clear mineral buildup and keep flow rates strong

    A well-maintained water heater runs more efficiently, recovers faster, and can last years longer than one that’s neglected.

    As a real estate professional and a homeowner, I’ve learned that having the right people in your corner is everything. In this business, clients often become friends — and many become like family. When I refer someone to one of my vendors, I’m putting more than their name on the line. I’m putting my own reputation and my client’s trust in their hands. That’s something I take very seriously. I’m fortunate to have several plumbers I absolutely trust, and John and his crew have earned a place on that very short list. Recently, I was working with a buyer who was under contract on a home. We did exactly what we’re supposed to do — our due diligence, inspections, and further investigation when something didn’t seem right. We initially believed the home had an issue with the PRV/pressure-reducing valve. After John got involved and actually took the time to investigate the problem, we learned something important: the problem wasn’t with the home at all. It was a city water-pressure issue. Here’s the part that says everything about John and the way he does business. He didn’t charge my client. But even more impressive — he didn’t simply say, “It’s the city’s problem,” and walk away. John has had someone continue monitoring the situation so that once the city addresses its side of the issue, we can make sure this buyer — soon to be the new homeowner — isn’t left dealing with a problem after closing. Think about that. The job wasn’t his problem. There wasn’t an invoice to collect. There wasn’t anything forcing him to stay involved. He stayed involved because he cared about the outcome. That’s service. That’s integrity. And THAT is why relationships matter so much to me in real estate. I don’t want a list of vendors who simply answer the phone. I want people I can confidently put in front of my clients and know they’re going to care for them the same way I would. John and his crew have shown me that repeatedly. They show up, investigate the problem instead of guessing, communicate, and make every effort to ensure things are addressed properly — not just quickly. Anybody can provide a service. The people you remember are the ones who take ownership even when they don’t have to. John, thank you for taking care of my clients, protecting the relationship and trust I’ve built with them, and reminding me what exceptional service actually looks like. That’s the kind of person I’m proud to refer.
    Response from the owner:Thank you so much for taking the time to share this. Your trust means a great deal to John and our entire team, especially knowing that when you refer one of your clients to us, you’re trusting us with a relationship and reputation you’ve worked hard to build. Our goal is always to find the actual cause of the problem, communicate honestly, and do what’s right for the customer—even when that means there isn’t a repair for us to make. We truly appreciate your continued confidence in Paynes Plumbing & Electric and are grateful to be one of the companies you trust to take care of your clients. Thank you again for the kind words, the referrals, and for trusting us to be in your corner. We don’t take that lightly!

    John Payne Plumbing and Electrical is absolutely exceptional. John and his crew recently replaced our old septic wastewater pump, installed a brand-new pump system, and replaced the float switches and alarm sensors. They also pulled entirely new electrical wiring, conduit, switches, breakers, and alarms from the house to the pump station.Throughout the entire process, they were honest, highly professional, and arrived exactly on time. They didn't just do the heavy lifting; they completed rigorous system testing and took the time to educate me on how the new setup operates.They were incredibly clean, picked up after themselves, and took great care of my property. It is rare to find such honest subcontractors who do high-quality work. Best of all, their pricing is very reasonable and they are not out to gouge their customers. I highly recommend them and will absolutely use them again in the future!
    Response from the owner:Thank you so much for the incredible review! We truly appreciate you trusting Paynes Plumbing & Electric with your septic wastewater pump replacement and the electrical work needed for the new system. Our team takes pride in doing the job right, thoroughly testing everything, keeping the work area clean, and making sure our customers understand how their new system operates. We’re grateful for your recommendation and look forward to being there whenever you need us in the future!

    John and Jesse came out to Anderson County to locate a septic system on a property for a new construction They arrived within the given time frame, they called when on their way as we requested prior, they immediately assessed the situation and explained everything to us- my Grandparents are in their 90’s trying to get this project done and John was EXCELLENT with explaining it all , and went out of his way to consult with fellow professionals and help us figure out the next steps to take in the process. Both he and his employee were very patient, kind, respectful, and this man had so much knowledge on this stuff!!! We were so impressed by them - He didn’t charge a thing as our situation was different from the norm , HONEST PROFESSIONAL AND HUMAN DECENCY in these country boys- I’d recommend them every time!
    Response from the owner:Thank you so much for the thoughtful review! We’re glad John and Jesse were able to help locate the septic system, explain everything clearly, and help determine the best next steps. Taking the time to answer questions and treat our customers with honesty, patience, and respect is extremely important to us. We truly appreciate your kind words and recommendation. Thank you for trusting Paynes Plumbing & Electric!

    John and Jesse were awesome! They weren't even originally supposed to do the job however they made sure we were number 1 priority when an accidental construction project cut our water.

And we got them to replace our PRV! Very quick and efficient

    I can’t say enough good things about John and Payne’s Plumbing. After buying a new home, I ran into an unexpected issue that forced me to postpone my tankless water heater installation. Once everything was resolved, I reached back out expecting to schedule for another day. Instead, John told me he could still make it out that same day. Not only did he install the tankless water heater, but he also took the time to look over a few other plumbing concerns I had and answered all of my questions. That kind of customer service is hard to find. John is honest, professional, and takes pride in his work—and it shows. If you’re looking for a plumber who stands behind his work, communicates well, and truly cares about his customers, I highly recommend Payne’s Plumbing. You won’t be disappointed.
    Response from the owner:Thank you so much for this incredible review! We truly appreciate you taking the time to share your experience. We're glad John was able to accommodate your schedule and get your tankless water heater installed once everything was ready. Taking the time to answer questions and make sure our customers feel informed and confident is something we take seriously. Don't hesitate to reach out if we can help with anything in the future!

    Paynes Plumbing and Electric was able to come out and diagnose our issue the same day we called. They were thorough in explaining the problem, the solution, and were willing to work with my schedule to resolve the problem. I found the staff respectful and personable and have already contacted them for additional work on separate issues.

    Next day service by two very professional and courteous technicians, both named Jesse!

I could not have been more pleased and I will certainly call on them again for any future plumbing needs.
