Water Heater Repair 

You step into the shower expecting hot water. Instead, you get a blast of cold. Or maybe the water runs hot for a few minutes and then turns lukewarm. Or perhaps you noticed a puddle forming at the base of the tank in the basement. Whatever the symptom, a water heater that is not working properly disrupts your entire day. Kaleb’s Kustom Plumbing repairs gas and electric water heaters throughout Pittsburgh and the surrounding communities. We identify the root cause, explain your options, and complete the repair correctly. To schedule service, call us at (412) 694-3938 or contact us online.

What You Can Safely Check Before Calling

A few simple checks may resolve the issue or help you describe the problem accurately when you call.

  • Check the circuit breaker. For electric units, confirm the breaker has not tripped.

  • Check the pilot light. For gas units, see if the pilot is lit. If it is out, follow the manufacturer’s relighting instructions. If it will not stay lit, call us.

  • Check the thermostat. Confirm the temperature setting is where it should be. Refer to your owner’s manual.

  • Check for leaks. Note whether water is coming from the tank itself or from a fitting or valve. This distinction matters.

  • Check the age. The manufacturing date is usually on a sticker on the tank. If the unit is over 10 years old, repair may not be the best investment.

Do not attempt repairs yourself. Water heaters involve electricity, gas, and pressurized water. Incorrect work can cause electrocution, gas leaks, or significant water damage.

What Is Actually Wrong With Your Water Heater

Water heater problems follow recognizable patterns. The symptom you are seeing usually points to a specific cause.

No Hot Water At All

This is the most common call we receive. The cause depends on whether your unit is gas or electric.

Electric units: A tripped circuit breaker, a burned-out heating element, or a failed thermostat are the usual suspects. If the breaker is fine and the unit has power, the element or thermostat is likely the problem.

Gas units: A pilot light that has gone out, a faulty thermocouple, a failed gas valve, or a supply issue are the common causes. If you smell gas, leave the building immediately and call 911 or your gas utility from outside. For gas-related issues, our gas line repair service can help.

Water That Runs Hot Then Cold

This fluctuating pattern is frustrating and often points to one of two things.

A broken dip tube. The dip tube carries cold water to the bottom of the tank for heating. If it breaks, cold water mixes with hot water at the top, causing temperature swings.

Sediment buildup. Over time, minerals settle at the bottom of the tank. This layer of sediment traps heat and causes uneven temperatures. It also forces the unit to work harder, shortening its lifespan.

Water That Never Gets Hot Enough

If the water is warm but never truly hot, the thermostat may be set too low, or the heating element or burner may be failing. In gas units, a dirty burner or low gas pressure can also be the culprit.

Rusty or Discolored Hot Water

If only the hot water is rusty or has a metallic taste, the anode rod inside the tank has likely failed. The anode rod is designed to corrode sacrificially to protect the tank. When it is gone, the tank itself begins to rust from the inside. At this point, replacement is usually the only option. If replacement makes more sense, our water heater installation and replacement service covers that.

Rumbling, Popping, or Banging Noises

These sounds come from sediment at the bottom of the tank. When the burner or element heats the tank, water trapped beneath the sediment boils and pops. The unit is working harder than it should, and the tank is weakening. Flushing the tank can help if the sediment has not hardened, but severe buildup often means the unit is near the end of its life.

Water Pooling Around the Base

Where the water is coming from matters.

From the tank itself: A leaking tank cannot be repaired. The steel has corroded through, and replacement is the only option.

From a fitting, valve, or the T&P valve: This may be repairable. A loose connection, a failed valve, or a faulty temperature and pressure relief valve can often be fixed. If you are unsure whether the leak is from the water heater or another source, our leak detection service can locate the source.

Pilot Light Keeps Going Out

In gas units, a pilot light that repeatedly extinguishes usually indicates a faulty thermocouple, a dirty pilot tube, or a draft issue. This is not a DIY repair. Call a professional.

Sulfur or Rotten Egg Smell

This odor can indicate bacteria growing in the tank or a failing anode rod. It is more common in homes with well water but can occur with city water as well. A new anode rod or a tank flush may resolve it.

How We Diagnose the Problem

Accurate diagnosis prevents wasted money on the wrong repair.

We start by listening. What have you noticed? When did it start? Is the problem constant or intermittent? These details guide the diagnosis.

We inspect the unit. We check the thermostat, heating elements or burner assembly, pilot components, anode rod, and all visible connections. We look for corrosion, sediment, and leaks.

We test components. For electric units, we use a multimeter to test elements and thermostats. For gas units, we check the thermocouple, pilot assembly, and gas pressure.

We explain what we found. You hear a clear explanation of the problem, the repair options, and the cost before any work begins.

We complete the repair. Most common repairs are done in a single visit. Our trucks carry common parts.

We verify the repair. We test the unit to confirm proper operation and check for leaks before we leave.

Repair or Replace: An Honest Assessment

Not every water heater problem warrants a repair. Sometimes replacement is the smarter financial decision.

Repair makes sense when:

  • The unit is under 8 years old

  • The problem is a replaceable component — heating element, thermostat, thermocouple, valve, or dip tube

  • The tank itself is intact

  • The repair cost is well below half the price of a new unit

Replacement is usually the better call when:

  • The tank itself is leaking — this cannot be repaired

  • The unit is over 10 to 12 years old

  • Repairs are becoming frequent

  • Hot water is rusty or discolored, indicating internal corrosion

We do not push replacement when a repair will solve the problem. We also do not recommend pouring money into a unit that is failing from the inside out. If replacement makes more sense, our water heater installation and replacement service covers that.

Why Pittsburgh Water Heaters Fail

Pittsburgh’s water and climate create specific conditions that affect water heater lifespan.

Sediment from local water. Pittsburgh’s water supply carries minerals that settle at the bottom of the tank over time. This sediment insulates the burner or element from the water, forcing the unit to work harder and shortening its lifespan.

Freeze risk for exterior units. If your water heater is in a garage or unheated space, Pittsburgh winters can cause supply lines to freeze. Insulating pipes and addressing drafts before winter prevents expensive repairs. If a pipe has already frozen and burst, our plumbing repair service can help.

Older housing stock. Many Pittsburgh homes have water heaters that were installed decades ago. When parts fail on older units, replacement parts can be difficult to source, making repair less practical.

Hard water effects. While Pittsburgh’s water is not among the hardest in the country, mineral content still takes a toll on heating elements and tank linings over time.

Questions Homeowners Ask

How much does water heater repair cost in Pittsburgh?

Costs vary depending on the problem and the parts needed. A thermocouple replacement costs less than a heating element replacement or a gas valve repair. We provide a clear estimate before starting work.

How long does a water heater repair take?

Most common repairs are completed in a single visit, usually within a few hours. Repairs requiring special-order parts may take longer.

Do you repair both gas and electric water heaters?

Yes. We work on both gas and electric models, including tank and tankless units. For gas-related issues, see our gas line repair page.

My water heater is leaking. Can it be repaired?

It depends on where the leak is coming from. If the tank itself is leaking, it cannot be repaired and must be replaced. If the leak is from a fitting, valve, or the temperature and pressure relief valve, a repair may be possible. If you are not sure where the leak is coming from, our leak detection service can help.

The pilot light on my gas water heater keeps going out. What should I do?

A pilot light that repeatedly goes out usually indicates a faulty thermocouple, a dirty pilot tube, or a draft issue. This is not a DIY repair — call us to diagnose and fix the problem safely.

Is it worth repairing a 12-year-old water heater?

Generally, no. At that age, the unit is near the end of its expected lifespan, and repair costs may not be a good investment. We can assess the specific situation and give you an honest recommendation. If replacement is the better option, our water heater installation and replacement service covers that.
