Signs Your Water Heater Needs Repair

Some problems show up gradually. Others hit all at once. Here’s what to watch for:

No hot water at all
Water not getting as hot as it used to
Hot water runs out faster than normal
Temperature fluctuates during use

Rusty or discolored hot water
Metallic taste from hot taps
Sediment or particles in hot water

Popping or rumbling during heating
Rattling or squeaking sounds
Hissing or sizzling from the tank
Banging when the burner ignites

Water pooling around the tank base
Moisture on pipes or connections
Rust or corrosion on the tank exterior
Pilot light won’t stay lit (gas units)

Unit cycles on and off frequently
Takes longer to heat water than before
Higher energy bills without increased usage

Catching problems early often means a simple repair instead of full replacement. If you notice any of these signs, call before a small issue becomes a big one.

Common Water Heater Problems We Fix

Most water heater issues come down to a handful of causes. Our technicians diagnose these quickly:

Thermostat Issues: The thermostat controls water temperature. When it fails, water may be too hot, too cold, or inconsistent. We test, calibrate, or replace thermostats on both gas and electric units.
Heating Element Failure (Electric): Electric water heaters use one or two heating elements. When an element burns out, you get less hot water or none at all. We test elements and replace them as needed.
Pilot Light Problems (Gas): Gas water heaters rely on a pilot light to ignite the burner. If the pilot won’t stay lit, the problem is usually the thermocouple, gas valve, or pilot assembly. We diagnose and fix all three.
Sediment Buildup: Las Vegas water is hard. Minerals settle at the bottom of the tank over time. This buildup reduces efficiency, causes popping noises, and can damage the tank. We flush tanks to remove sediment.
Pressure Relief Valve Issues: The temperature and pressure (T&P) relief valve is a safety device. If it leaks or won’t open, the valve needs replacement. We test and replace T&P valves.
Anode Rod Deterioration: The anode rod protects your tank from corrosion by attracting minerals that would otherwise attack the tank walls. When the rod wears out, the tank starts rusting from the inside. We inspect and replace anode rods.
Dip Tube Problems: The dip tube directs cold water to the bottom of the tank for heating. If it breaks, cold water mixes with hot water at the top, and you get lukewarm output. We replace broken dip tubes.
Leaking Connections: Inlet and outlet pipes, drain valves, and T&P valve connections can all develop leaks. We tighten or replace fittings and valves as needed.

Las Vegas Water Heater Challenges

In Las Vegas, hard water (278 ppm mineral content) accelerates sediment buildup inside tank water heaters, causing the popping noises and reduced efficiency we see daily. Our desert environment also means extreme temperature swings that stress components, while garage installations—common throughout the valley—experience additional heat stress during summer months when ambient temperatures exceed 110°F. These local conditions mean Las Vegas water heaters often need repairs sooner than national averages, making regular maintenance and prompt repairs even more important.

How Water Heater Repair Works

Here’s what to expect when we come out:

Diagnose the Problem We inspect the unit, test components, and identify exactly what’s causing the issue. No guessing—we find the actual problem.
Explain Your Options We tell you what’s wrong, what it takes to fix it, and what it costs. If replacement makes more sense than repair, we’ll say so.
Complete the Repair Once you approve the work, we fix the problem. We carry common parts on our trucks, so most repairs finish the same visit.
Test the System We verify the repair worked. We check for leaks, confirm proper heating, and make sure safety devices function correctly.
Clean Up We leave your space the way we found it. No mess left behind.

How Long Repairs Take

Repair Type	Typical Time
Thermostat replacement	30-60 minutes
Heating element replacement	1-2 hours
Pilot light/thermocouple repair	30-60 minutes
Tank flush (sediment removal)	30-45 minutes
T&P valve replacement	30-45 minutes
Anode rod replacement	1-2 hours
Dip tube replacement	1-2 hours
Multiple repairs	2-4 hours

Repair vs. Replacement: How to Decide

Sometimes repair is the right call. Sometimes replacement makes more sense. Here’s how to think about it:

Factor	Lean Toward Repair	Lean Toward Replacement
Age	Under 8 years old	Over 10 years old
Repair cost	Less than 50% of new unit	More than 50% of new unit
Repair history	First or second repair	Multiple repairs recently
Tank condition	No rust, no leaks	Rust, corrosion, or tank leak
Efficiency	Still heats well	Takes forever, bills climbing

Always replace if:

The tank itself is leaking (not a valve or connection)
You see significant rust inside the tank
The unit is over 12 years old and needs major repair

Repair usually makes sense if:

The unit is under 8 years old
The problem is a single failed component
The tank is in good condition

Not sure which option makes sense? We’ll walk you through it and help you choose the right solution for your home.

Frequently Asked Questions

Most water heater repairs in Las Vegas cost $150 to $500. Simple fixes like thermostat replacement or pilot light repair run $150 to $250. Heating element replacement costs $200 to $350. More complex repairs involving multiple components can reach $400 to $500. We provide exact pricing before starting work. Contact us for a diagnosis and exact pricing.

It depends on the repair. Minor fixes like a thermostat or T&P valve are worth doing even on older units. Major repairs—or any repair costing more than half the price of a new unit—usually aren’t worth it at 10+ years. If the tank itself is leaking or corroded, replacement is the only option regardless of age.

Popping or rumbling sounds usually mean sediment buildup at the bottom of the tank. Las Vegas hard water accelerates this problem. When the burner heats water trapped under sediment, it creates steam bubbles that pop. A tank flush often solves the noise. If the buildup is severe, other damage may have occurred.

It depends on where the leak is. Leaks from valves, connections, or pipes can usually be repaired by tightening or replacing parts. Leaks from the tank itself—the actual body of the water heater—cannot be repaired. A leaking tank means the unit has corroded through and needs replacement.

Most repairs take 1-2 hours. Simple fixes like thermostat replacement or pilot light repair finish in 30-60 minutes. Heating element replacement or anode rod replacement takes 1-2 hours. If we need to order a part, we’ll schedule a follow-up visit. Emergency repairs are prioritized to restore your hot water as fast as possible.

Yes. Turn off the power first—flip the breaker for electric units or turn the gas valve to “off” for gas units. Then turn off the cold water supply valve above the heater. This stops more water from entering and reduces damage. Call us immediately for emergency service.
