    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.

    Can’t brag on them enough. Called multiple companies for an emergency leak in my basement. After being told it would be days from others, Mr. Payne had someone out in a matter of hours. Also came back the following week when I had other concerns and was able to fix different issue same day. Jesse was kind, courteous and did great work. Great business.
    Response from the owner:Josh, thank you so much for taking the time to leave us such a great review! We know how stressful an unexpected leak can be, so we're glad we could get someone out quickly and take care of everything for you. We’ll be sure to pass along your kind words to Jesse! We truly appreciate your trust in our team and your support of our business!

    Response from the owner:Hi Maria! You must have the wrong company as we have no record of interacting. There is a different company with a similar name to us that may be the ones you meant to leave a review for.

    We needed a pump tank replaced with new electrical and alarm panel. John and his team scheduled quickly and got the job done with no issues. His price was very fair and I would trust him to do any work at my home.

We’re glad John and the team could get everything scheduled quickly and taken care of smoothly. We truly appreciate your trust in Paynes Plumbing & Electric and are always here if you need us!

    We had a rancid smell coming from our laundry room. They quickly came out and assess the problem and put in motion plans to fix it. Plumbing can be a terrifying repair for someone like me. What was needed was beyond what I could afford in one swoop. They graciously worked with me allowing me to split it up into 2 payments. Not only efficient, kind, honest, they have great customer service. I know I found my new plumber! I think you will too if you give them a shot!
    Response from the owner:Thank you so much for this wonderful review! We understand how stressful unexpected plumbing issues can be, especially when they come with an unexpected expense. We always do our best to make the process as easy as possible for our customers. We're so glad we could help get everything taken care of and truly appreciate you trusting us with your home. It means a lot to know we've earned your business, and we're always here if you need us again!

    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.

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. They made sure our water was back on, very honest, timely and even answering after hours calls! Will definitely keep the business card and number for anything in the future. And we got them to replace our PRV! Very quick and efficient
