Cogan Plumbing repairs and installs water heaters across Central Arkansas — both traditional tank units and tankless systems. Most tank water heaters last 8 to 12 years; if yours is leaking from the tank, making rumbling or popping sounds, producing rusty water, or no longer keeping up with hot-water demand, it’s time to have it looked at. We’re a licensed, insured, family-owned company, we quote a flat upfront price before any work, and we offer 24/7 emergency service for a failed or leaking heater. Call (501) 317-0637.
Water heater not working? Here’s what’s likely going on
A water heater rarely fails without warning — it usually gives you signs first. The trouble is that those signs are easy to ignore until the morning there’s no hot water, or worse, until you find a puddle around the base of the tank. Cogan Plumbing handles both ends of that story: diagnosing and repairing a heater that still has life in it, and replacing one that’s reached the end of the line.
We serve homeowners across Pulaski, Saline, Faulkner and Lonoke counties — Little Rock, North Little Rock, Sherwood, Maumelle, Conway, Cabot, Benton, Bryant and the surrounding towns. Whether you have a gas or electric tank unit, we’ll tell you honestly whether a repair makes sense or whether your money is better spent on a replacement.
Signs your water heater needs attention
- No hot water, or it runs out fast. A failed heating element, a bad thermostat, or sediment crowding the tank can all cause this.
- Rumbling, popping or crackling sounds. That’s the sound of hard-water sediment baked onto the bottom of the tank — very common in Central Arkansas.
- Rusty or discolored hot water. Often a sign of corrosion inside the tank or a spent anode rod.
- Water pooling around the base. A leak from the tank itself is not repairable — the tank needs to be replaced.
- The heater is 10-plus years old. Past that age, repair costs start to chase the cost of a new, more efficient unit.
- Higher energy bills with no change in usage — a heater fighting sediment buildup works harder.
Repair or replace? How we think about it
This is the question every homeowner wants answered honestly, so here’s how we approach it. We weigh four things: the age of the unit, the cost of the repair, whether the tank itself is sound, and how reliable the heater has been lately.
- Repair usually makes sense when the tank is intact, the unit is under roughly 8 years old, and the failure is a single replaceable part — a heating element, thermostat, thermocouple, or gas valve.
- Replacement is usually the smarter call when the tank is leaking, the unit is past 10 years, or you’re facing a major repair on an aging heater that will likely need another repair soon.
We’ll lay out the numbers and let you decide. There’s no upsell pressure — just a straight answer from a licensed plumber.
Why hard water is hard on water heaters in Central Arkansas
Water across much of Central Arkansas carries a fair amount of dissolved mineral content. Every time your heater runs, some of that mineral drops out of the hot water and settles as scale on the bottom of the tank. Over the years that layer of sediment does three things: it insulates the burner or element from the water so the heater works harder, it makes that telltale popping noise, and it accelerates corrosion.
The practical defense is an annual flush — draining the tank to clear out sediment before it bakes on. It’s a small maintenance task that can add years to a heater’s life. If your unit has never been flushed and it’s a few years old, that’s worth a conversation when we visit.
Choosing a new water heater
When replacement is the right move, the main decisions are tank versus tankless, fuel type, and capacity.
- Traditional tank heaters have a lower upfront cost and a simpler installation. A 40- or 50-gallon unit covers most Central Arkansas households.
- Tankless (on-demand) heaters cost more upfront but heat water only when you need it, last longer, and free up space. We install these too — ask us about a tankless system if endless hot water and lower standby loss appeal to you.
- Gas versus electric usually comes down to what your home is already set up for. We’ll work with whichever your home supports and can advise if a change makes sense.

Frequently asked questions about water heaters
How long should a water heater last?
A traditional tank water heater typically lasts 8 to 12 years. Tankless units often last longer — 15 to 20 years with proper maintenance. Hard water shortens those lifespans, which is why an annual flush matters in Central Arkansas. If your tank heater is past 10 years and acting up, replacement is usually worth pricing out.
Why is my water heater making popping or rumbling noises?
That sound is hard-water sediment that has settled and baked onto the bottom of the tank. As the burner heats water trapped under that layer, it bubbles and pops. It’s very common here. A tank flush often quiets it down and helps the heater run more efficiently; if buildup is severe, it may signal the tank is nearing the end of its life.
Is a leaking water heater an emergency?
If water is leaking from the tank body itself, yes — the tank cannot be repaired and it will only get worse. Shut off the water supply to the heater and call us. Our emergency line is available 24/7. A small drip from a fitting or valve is less urgent but still worth addressing promptly.
Should I repair my water heater or replace it?
If the tank is sound, the unit is under about 8 years old, and the problem is a single part like an element or thermostat, repair usually makes sense. If the tank is leaking, the unit is past 10 years, or the repair is expensive, replacement is typically the better value. We’ll give you the numbers and an honest recommendation, and you decide.
How often should a water heater be flushed?
About once a year for a tank water heater, more often if your water is especially hard. Flushing clears sediment before it bakes onto the tank, which protects efficiency and extends the heater’s life. We can flush your heater during a service visit and show you what came out.
What size water heater do I need?
It depends on your household’s hot-water demand — number of people, number of bathrooms, and usage habits. A 40- or 50-gallon tank suits most Central Arkansas homes, while larger households or those with high simultaneous demand may want a larger tank or a tankless unit. We’ll size it correctly for your home as part of a free quote.
Do you install both gas and electric water heaters?
Yes. We install and repair both gas and electric tank water heaters, as well as tankless systems. We’ll work with whatever fuel type your home is set up for and let you know if switching makes practical sense for your situation.
