Water Heater Repair Duncanville, TX

When your water heater quits, life hits pause. Showers turn cold, dishes pile up, and the morning routine turns into a game of “who’s using the kettle next?” That’s when Duncanville homeowners and businesses call One Source Plumbing. We’ve been fixing, replacing, and maintaining water heaters across North Texas for more than two decades — and we’ve seen just about everything that can go wrong.

Experience You Can Count On

Our founder started in the plumbing trade over 24 years ago, crawling under homes and into attics before running his own company right here in the Duncanville area. Those years taught us what matters most — honest pricing, fast response, and work done right the first time.

When you call us, you’re not getting a rookie or a random subcontractor. You’re getting a licensed plumber who knows how to diagnose your water heater quickly and explain the problem in plain English. Whether your tank’s leaking, the pilot light keeps going out, or your tankless unit has lost its spark, we’ll find the cause and fix it.

Honest Work. Local People. Reliable Results.

We live here too. That means our reputation travels fast — from Cedar Hill to DeSoto to Duncanville. Every job is a handshake with the community, so we treat your home like our own. We clean up before we leave, show up when we say we will, and never surprise you with a mystery fee.

If you’re a homeowner tired of cold showers or a local business owner with a water heater down before a busy day, we’ve got you covered.

Common Water Heater Problems We Fix

You’d be surprised how often a small issue turns into a major headache if left alone. Here’s what we see most often:

• No hot water at all – usually a failed heating element or gas control valve.
• Rust-colored water – corrosion inside your tank or pipes.
• Popping or banging sounds – sediment buildup from hard water.
• Leaking around the base – pressure valve or tank failure.
• Water gets hot, then cold – thermostat or dip tube issue.

Don’t worry — we don’t just throw parts at the problem. We test, verify, and repair what’s necessary. If your system’s beyond saving, we’ll guide you through replacement options that make sense for your home and budget.

Tank or Tankless — We Handle Both

Whether you’ve got a standard 40-gallon tank in the garage or a sleek tankless model mounted on the wall, we’re trained to repair them all. Tankless systems can be great for efficiency, but they also require proper flushing and maintenance. Our techs handle everything — descaling, sensor checks, and full replacements if needed.

Real People, Real Service

One Source Plumbing isn’t a call center that ships jobs out. When you contact us, you’ll speak with our local office — folks who actually know Duncanville streets and traffic. We schedule around your day, show up on time, and explain exactly what’s happening before any work begins.

We once had a customer call late at night because their water heater burst right before their kid’s birthday party. Within an hour, our team was there with parts, towels, and a can-do attitude. That’s what we mean by service.

Maintenance Saves Money

Most water heater problems build up slowly. A yearly flush and quick inspection can add years to your system’s life. We drain sediment, test safety valves, and check electrical and gas components to make sure everything’s running smoothly. Think of it like an oil change for your plumbing — a small bit of maintenance can prevent a major breakdown later.

Replace or Repair? We’ll Help You Decide

If your water heater is over 10 years old or leaking from the tank, replacing it might be the smarter move. We’ll walk you through your options, explain what’s efficient, and help you choose a system that fits your usage and budget. We install both traditional and tankless systems and haul away the old one.
