Common Las Vegas Water Heater Problems We Fix—Fast

If you’re experiencing a water heater problem, you’re not alone. Due to our hard water and the demands on these units, certain issues are extremely common. Our licensed technicians have seen it all and can fix your water heater issue correctly the first time.

Popping, Banging,
or Rumbling Noises

The Cause: This is the most common sign of severe sediment buildup in your water heater tank. Las Vegas’s hard water creates a layer of mineral deposits at the bottom of the tank. Water gets trapped underneath and boils, causing the strange noises you hear. This is a clear indicator of reduced heating efficiency.

Our Solution: We can flush the tank to remove the sediment, restoring quiet operation and improving efficiency.

No Hot Water
or Lukewarm Water

The Cause: A lack of hot water typically means there’s an issue with the heating mechanism. For an electric water heater, this is often a broken thermostat or a heating element failure. For gas water heaters, it’s frequently a faulty pilot light or gas supply issue. It can also be caused by a faulty dip tube that mixes cold water with your hot water supply.

Our Solution: Our technicians will test the thermostat, heating elements, and gas assembly to pinpoint the exact part that needs repair or replacement.

Water Leaking
from the Tank

The Cause: Puddles of water around your unit are a serious issue. A leak can be caused by a number of things, including a loose inlet connection, a failing drain valve, a malfunctioning temperature-pressure relief valve, or excessive pressure buildup. The worst-case scenario is a corroded, leaking tank.

Our Solution: We will immediately identify the source of the leak to prevent water damage. While connections and valves can often be fixed, a leaking tank from corrosion means the unit must be replaced.

Rusty Water or
a Foul Odor

The Cause: If your hot water is discolored or has a foul odor, it often indicates one of two things: the inside of your water heater tank is corroding, or there is bacterial growth inside the tank. This internal corrosion is often a sign that the anode rod, which is designed to prevent corrosion, has been completely used up.

Our Solution: If caught early, replacing the anode rod can solve the problem and extend the life of your heater. We can also flush and treat the tank to eliminate bacteria.

"Repair vs. Replace" Decision Framework

Repair or replace? When your unit fails, deciding between a service call and a new water heater installation can be tough. As your trusted local experts, we believe in giving you honest advice, not a sales pitch. We’ll help you make the most cost-effective decision for your home with this simple framework.

#1: Check the Age of Your Unit

The average lifespan of a traditional water heater is 7-10 years. If your old water heater is under 7 years old, a repair is generally the best option. If it's over 9 years old and showing problems, a water heater replacement is often the smarter financial choice.

#2: Consider the Repair History

Are you calling for heater repair service every year? Frequent breakdowns are a clear sign that the unit is nearing the end of its life. Investing in constant repairs for an old water heater can quickly add up to more than the cost of a replacement.

#3: Evaluate the Severity of the Problem

Some issues are terminal. If the water heater tank itself is leaking due to rust or corrosion, it cannot be repaired safely. In this case, a new water heater installation is required to prevent major water damage.

#4: Assess the Cost of the Repair

We provide free estimates so you can make an informed decision. If the cost of the repair is approaching 50% of the price of a new unit, upgrading to a modern, more energy-efficient model will provide better long-term value and lower your future energy costs.

Las Vegas Water Heater Repair FAQ

How much does it cost to repair a hot water heater?

The cost of a water heater repair depends on several factors, primarily the part that has failed. Replacing a simple component like a pressure relief valve is less expensive than replacing a major heating element or gas valve assembly. Bob’s Repair provides free estimates so you know the exact cost before we begin work.

Is it worth it to repair a hot water heater?

It often depends on the age of the unit and the cost of the repair. It is generally advisable to repair a water heater that is under 7 years old. If your unit is over 9 years old, shows signs of corrosion, or needs frequent repairs, it is usually more cost-effective to replace it with a new, energy-efficient model.

What is usually the most common water heater problem?

In Las Vegas, the most common issues are related to sediment buildup from hard water, which causes overheating, strange noises, and reduced efficiency. Beyond that, a lack of hot water caused by a failed heating element (in electric models) or a pilot light issue (in gas models) is a very frequent reason for service calls.

Do I call a plumber or an electrician for a water heater?

For almost all water heater issues—including leaks, no hot water, gas supply problems, and valve malfunctions—a licensed plumber is the correct professional to call. The only exception is if the problem is isolated to the circuit breaker or the dedicated electrical wiring to the unit. As a comprehensive home service company, Bob’s Repair’s licensed technicians are equipped to handle the entire system safely.

How long should a water heater last?

The lifespan depends on the type of unit and maintenance. A traditional tank water heater typically lasts 7-10 years with proper care. Modern tankless water heaters are more durable and can last over 20 years.
