Water Heater Plumbing Issues: Who You Gonna Call?

October 31, 2025

We often get the question, “Does a plumber replace (or install) a water heater?” and YES! A licensed plumber is typically the go-to professional for water heater plumbing needs, including repairs, installations, and full replacements (you may also need an electrician, depending on the electrical demand of the replacement water heater). But basically, whether it’s a traditional tank unit or tankless water heater system, an experienced water heater plumber ensures the job is done safely, efficiently, and up to local plumbing code.

Another question we often get is…

Do I Need to Call a Plumber for Water Heater Repair or Can I DIY It?

There are many common water heater plumbing issues; a confident homeowner can tackle some, but not all. Here are some problems that crop up with water heaters that may signal the need for water heater service (and whether that can be DIYed or requires pro help):

  • No Hot Water: If your water is suddenly cold, the fix might be as simple as a tripped breaker. A tripped breaker can be checked at the panel by the homeowner, but if it’s not tripped, the issue could be due to a broken heating element or thermostat, and those fixes require a plumber for water heater repair.

  • Inconsistent Temperature: Fluctuating water temperatures often indicate a failing thermostat or sediment buildup. Flushing the tank can help, but if it doesn’t, call a plumber.

  • Water Leaks: Water pooling at the base of the heater could mean a leaky valve - or a cracked tank. Intrepid DIYers can fix minor valve issues, but cracked tanks require an immediate water heater replacement, so you’ll likely want a plumber.

  • Strange Noises: Rumbling or popping sounds usually point to sediment buildup. Again, you can try flushing the tank, but stubborn buildup might require professional help.

  • Discolored or Smelly Water: Rusty or smelly water can indicate anode rod corrosion. If this is the case, replacing the rod is best done by a professional plumber.

  • Water Heater Runs Out of Hot Water Quickly: If the hot water runs out faster than usual, it might be time for an upgrade or replacement, and a plumber is the professional who can best assess whether it’s time for that investment.
