CALL (903) 900-0430

Most plumbers reach for "you need a new one" before they reach for a wrench. We don't. Continental Plumbers has been repairing water heaters across Union County since 1985 — and the honest truth is that most failures are a thermocouple, a heating element, a thermostat, or a valve. Fixes, not replacements. We diagnose, we tell you straight, and most repairs we handle same-day.

Common Water Heater Problems We Fix

Most Water Heater Issues Are a Repair, Not a Replacement

Here’s what brings most calls in — and what we typically find when we diagnose:
No Hot Water

Pilot light out, broken thermostat, failed heating element (electric), tripped breaker, or gas valve issue. Usually a same-day fix.

Rumbling or Popping Sounds

Sediment buildup at the bottom of the tank. A proper flush often extends the unit's life by years.

Water Not Hot Enough

Thermostat needs adjustment or replacement, broken dip tube, or sediment limiting capacity. Usually fixable without replacement.

Running Out of Hot Water Too Quickly

Failing heating element, sediment buildup, broken dip tube. Sometimes a sign the tank is undersized for your home — but often repairable.

Pilot Light Won't Stay On

Bad thermocouple (most common — cheap fix), gas valve issue, or venting problem. Don't ignore — gas issues are safety issues.

Rusty or Discolored Hot Water

Anode rod failing or tank corrosion. Anode rod is a cheap fix; tank corrosion usually means replacement is near.

Leaking Valve or Fitting

Pressure relief valve dripping, drain valve leak, or supply fitting issue. Usually repairable. Leaking from the tank itself is different — that's replacement territory.

Strange Smells (Especially Gas)

Smell of gas near the unit = shut off the gas valve and call immediately. Other smells (sulfur, metallic) usually mean anode rod or bacteria issues. Both fixable.

We Get It

The Concerns We Hear About Water Heater Repairs

"I don't want to spend $400 on a repair just to be told next month I need a new one."

Reasonable concern. When we diagnose, we look at the whole unit — not just the broken part. If we see the tank itself is near end-of-life (corrosion, age, repeated issues), we'll tell you that the repair is a bandaid before quoting it. You decide which way to go with full information.

"My heater is 12 years old. Is it even worth fixing?"

Sometimes yes, sometimes no. A thermocouple on a 12-year-old gas unit might be fine — they have years of life left if the tank is in good shape. A heating element on a 14-year-old electric tank that's already showing rust? Probably not worth it. We assess and tell you honestly.

"I had a plumber once who 'diagnosed' me into a new unit I didn't need."

We hear this constantly. Some plumbers default to replacement because the ticket is bigger. We default to repair when repair is the right answer — because the relationship is bigger than the ticket.

"My tenant called about no hot water at 6 AM."

Standard property manager call. Most no-hot-water situations we resolve same-day with a thermocouple, element, or thermostat fix. We communicate with your tenant professionally and bill clearly back to you.

When Repair Isn't Enough

The Honest Lines Between "Fix It" and "Replace It"

We’ll repair when repair makes sense. Here’s when we’ll tell you straight that replacement is the smarter call:
  • 🚫 The tank itself is leaking not a valve, not a fitting, but the tank wall. Once the tank goes, no repair will hold.
  • 🚫 The unit is over 12 years old AND giving you trouble — putting money into something this close to end-of-life rarely pays off.
  • 🚫 You're getting rusty hot water consistently corrosion inside the tank. Repair won't fix it.
  • 🚫 The estimated repair is over 50% of replacement cost at that ratio, replacing is almost always smarter.
  • 🚫 It's failed multiple times in the last year the unit is telling you something.

If any of these describe your situation, we’ll tell you when we diagnose — and walk you through replacement options without pressure. Learn about replacement →

The honest truth: If we can fix it for less than $400 and your unit has years left, we fix it. If we'd be sinking money into something near end-of-life, we tell you straight — and quote both options so you can decide.

Remodel Plumbing FAQs

Most repair calls same-day or next-day. No hot water situations and active leaks dispatched 24/7.
Honest answer — you usually don't until we diagnose. The age of the unit, the symptoms, and the condition of the tank all factor in. We tell you both options with pricing when we come out, so you can decide.
Yes. Tankless units have their own common issues — error codes, scale buildup, venting problems, ignition failures. We service all major tankless brands (Rinnai, Navien, Rheem, Bosch).
No — if anything, having a licensed plumber do the work keeps your warranty intact. DIY or handyman repairs are what void warranties. We document the repair for your records.
Often yes, especially in Union County where hard water is common. Sediment buildup is the #1 cause of popping/rumbling sounds. A proper flush can extend a unit's life significantly — and we'll tell you straight if your unit is too far gone for a flush to help.
