7 Signs Your Plano Water Heater Is Leaking (And What To Do About It)

dna plumbers

Water heaters work behind the scenes, quietly supplying hot showers and warm water for dishes—until something goes wrong. A leaking water heater isn’t just annoying; it can lead to serious damage if left unchecked. So how do you know if your water heater in Plano is leaking? Here are the key signs to watch for from our Plano plumbers before a small issue turns into a major problem.


1. Puddles of Water Around the Heater

This might seem obvious, but if you notice water pooling near your heater in your Plano home, it’s time to investigate. The leak could be coming from the tank, the pipes, or even the pressure relief valve. Small leaks can start slow, but they’ll get worse over time.

If left unattended, pooled water can also lead to mold growth and floor damage. If you’re seeing puddles regularly, and you’re in the Plano area, call to schedule a water heater repair with us! 


2. A Drop in Hot Water Supply

If your showers are suddenly lukewarm or you’re running out of hot water faster than usual, your water heater might be losing water due to a leak. This could indicate a crack in the tank or a malfunctioning heating element.

Additionally, fluctuating water temperatures might mean your system is struggling to maintain efficiency. If this is happening in your Plano home, you might need a water heater replacement.


3. Higher Water Bills

A hidden leak can lead to unexpectedly high water bills. If your monthly bill has jumped without an obvious reason, your water heater may be leaking—or you may have another plumbing issue that needs attention. Water leaks can go unnoticed for weeks, causing unnecessary waste and increased costs. If you suspect a problem, professional plumbing leak detection in your Plano home can help you find the culprit before your water bill skyrockets.


4. Rust or Corrosion on the Heater

Rust is never a good sign, especially on a water heater. If you spot corrosion on the tank or pipes, it means water has been leaking for some time. Rust weakens the structure of your heater, increasing the risk of a sudden failure.

Additionally, rust buildup in your water heater can lead to contaminated water, impacting both the performance and safety of your system. Regular inspections can help catch these issues before they become severe.


5. Strange Noises Coming from the Tank

If your water heater is making popping, hissing, or crackling sounds, it could be a sign of sediment buildup inside the tank. Over time, this buildup can cause overheating, tank damage, and cracks, leading to leaks. You may also notice a reduction in heating efficiency. Regular flushing of the tank can help prevent sediment accumulation and keep your system running smoothly for years.


6. Warm Spots on Your Floor

This is a sneaky sign that many homeowners miss. If you notice certain areas of your floor feeling warmer than others—especially near your water heater—you might have a slab leak caused by a leaking unit. Slab leaks are serious and can lead to foundation damage, wood rot, and mold growth. If you suspect an issue, it’s crucial to seek slab leak detection in your Plano home as soon as possible to prevent costly repairs.


7. Discolored or Bad-Smelling Water

If your hot water is coming out brown, rusty, or smells metallic, it could be due to rust inside your water heater. This often happens when the anode rod, which prevents rust, has worn out. Over time, untreated rust can lead to leaks, sediment contamination, and inefficient heating. In this case, you may need a water heater installation in your Plano home to ensure clean, safe hot water.


What to Do If Your Water Heater is Leaking

If you notice any of these signs, don’t wait! Even a small leak can cause big problems over time. Here’s what to do next:

  1. Turn off the power and water supply. If you have an electric heater, switch it off at the breaker. For gas heaters, turn off the gas valve. Then, shut off the water supply to prevent further leakage.
  2. Call a professional plumber. A licensed expert can diagnose the issue and determine whether you need water heater repair in your Plano home or a water heater replacement.
  3. Schedule a water leak detection service. If you’re unsure where the leak is coming from, a professional can help pinpoint the source before it causes serious damage.
