Signs You Need Water Heater Repair Service

Even though water heaters are designed to operate for a long time, you may notice indicators that you need to schedule a hot water heater repair in the future. Here are some of the warning indications that you need water heater services:

  • You’re repeatedly replacing a blown fuse in the fuse box, or resetting the circuit breaker.
  • Hot water is discolored or smells off.
  • The pressure of hot water is weaker than it once was.
  • There’s not enough hot water to complete chores and household tasks.
  • Water heats up slower than it used to.
  • You see water leaking from the water heater or nearby.
  • The hot water faucet only gives lukewarm water or cold water.

Types of Common Repairs for Water Heaters

Plumbers see a host of issues with hot water heater tank units and tankless water heaters every day. The most common electric and gas water heater problems we see? Leaks, bad anode rods, and temperature control issues. Below, we share a little bit about what causes these issues and how we fix them!

Water Leaks

Plumbers of all experience levels and skill sets have been finding leaks in water heaters for decades. Depending on the source of the leak, it may be relatively easy to fix, but even a small water heater leak can quickly develop into a major difficulty if left unattended. Here are some common sources of leaks and solutions:

  • The pressure relief valve is defective and needs to be replaced.
  • Water pressure is too high, causing a leak from your pressure relief valve. The pressure sends hot water spilling out of this tube. We may need to flush hot water pipes and water heater to remove sediment and mineral deposits, or replace the dip tube.
  • Mineral deposits cause heating elements to overheat, resulting the need to cleanse the unit or replace the heating element. Destruction of the glass liners and outer shell from mineral deposits and overheating could necessitate the installation of a new water heater.
  • Leaks at or around the water heater might occur if plumbing connections are not secure. If the supply and outgoing connectors on hot water pipes are slack, they must be tightened.

Anode Rod Replacement

If you want to avoid serious damage to the glass liners or outer shell of your hot water tank, replacement of the anode rod on a maintenance schedule is the solution. An anode rod should be replaced every five years in most cases, though homes with hard water may have to do so more often.

An anode rod sits down inside the water within the tank. It pulls water minerals to it, which causes the rod to disintegrate over time. If these minerals weren’t pulled away from the tank wall, they will corrode the tank wall over time and eventually cause leaking water and may require water heater installation service.

Temperature Control Issues

Another significant concern is cold or lukewarm water flowing from the water faucet. You may find that the water heater isn’t working at all, or doesn’t seem to be working as well as it used to. Temperature problems can be due to issues such as:

  • A failing thermostat that is unable to detect the precise temperature setting or the heat setting for the high temperature limit might cause the high temperature cutoff switch to activate erroneously. Part repair or replacement may be required.
  • Damaged heating elements that fail to create adequate heat may require the installation of a new gas or electric element, or the water heater may require replacement.
  • It’s possible that the water heater or hot water supply pipes aren’t properly insulated, resulting in heat loss. Adding insulation to hot water supply pipes or water heater tanks produces higher heat retention as water goes to hot water taps.
  • Heat cannot be generated if the pilot light is out or the pilot flame is doused underneath the access panel. It’s possible that the pilot light needs to be replaced.
  • The appliance cannot heat water due to a power interruption caused by defective circuit breaker. This may need the replacement of a circuit breaker.

It’s perfectly fine if you’re not a master in water heaters; Mr. Plumber is here to assist you! Any water heater repairs that you require will be completed by a licensed Indianapolis plumber in order to restore energy efficient hot water. Water heater repair services may be scheduled as soon as you discover unforeseen cold water, water leakage, or other water heater concerns in your Indianapolis area home.

Should I Repair My Water Heater or Replace It?

It’s time to start your research into water heater replacement if your unit is nearing, at, or beyond the average service life.

When you see any of these signs, it’s time for water heater replacement now!


The majority of water heater tanks are fabricated from steel, which means they will form rust at some point. You may see visible rust on the unit, or it may be internal. Corrosion or rust at the water heater’s temperature and pressure valve or inlet and outlet water connections are signs the unit has formed rust.

Rust isn’t always apparent on the exterior of the water heater, but that doesn’t mean it hasn’t already formed within. If you notice rust-colored water that only occurs when hot water is in use, this is a tell-tale sign of rust within the water heater. Water may also appear cloudy or have a metallic smell.

In homes with galvanized plumbing piping, determining the source of rust-colored water is more of a challenge, as the plumbing pipes themselves are also prone to rust. A good way to determine if rust-colored water is from your water heater or plumbing pipes is to drain the hot water storage tank.

Use five-gallon buckets to drain water from the storage tank. The first buckets are likely to appear rusty with either source. If rust-colored water still drains from your water heater by the third filled bucket, your water heater is the likely source and it’s time for water heater replacement.

A rusty water heater is not a reparable problem. Water heater replacement is the only solution to avoid water leaks. In some cases, rust-colored water is caused by a malfunctioning sacrificial anode rod, which is usually able to be replaced by a plumber.


Water carries minerals and other debris which settle in the bottom of a hot water storage tank over time. It also becomes hard through constant heating.

This hardened sediment within the hot water tank causes efficiency loss and damage to the unit. The water heater requires more energy to do its job with this sediment in place. Since the water heater must work harder to heat water, the metal tank experiences more wear. The metal becomes more brittle and is able to more easily crack and form small holes.

When a water heater tank is filled with hardened sediment, it starts to emit a rumbling, popping, knocking, or banging noise when in operation. This sound is caused by air bubbles within the sediment – the air bubbles start to boil along with water inside the tank.

When you hear this sound, it’s time to for water heater replacement. Also, be on the lookout for water leaks that stem from the small holes that have developed within the tank.

Drain Valve Malfunction

The sediment buildup in the bottom of a hot water tank has the potential to cause another problem – drain valve clogs.  Once sediment settles within the drain valve, it accumulates and blocks the valve from draining when needed. Water becomes trapped within the storage tank and you are then unable to drain the tank for routine flushing and maintenance.

To check drain valve function, follow these instructions:

  • Shut off the water heater’s fuel source
  • Attach a hose to the drain valve
  • Open one hot water faucet in your home and leave it open to rid the tank of negative pressure

If water is able to drain from the valve through the hose, the drain valve is not clogged. If water drains but is cloudy, you have a sediment issue within the tank. If water only trickles out or is unable to drain in any capacity, the drain valve is clogged. A clogged drain valve can mean serious sediment issues within the storage tank which require water heater replacement.

Water Outside the Unit

Water outside of your water heater tank is an obvious sign of a leak. Inspect the area and other sources to ensure fittings and connections are tight and not the cause of the leak, as well as check the temperature and pressure overflow pipe to see that it does not have a leak.

Unexplained water around your water heater often comes from small fractures within the tank. The tank’s metal expands when exposed to heat through the water heating process. This has the potential to cause minor fractures, which allow water to leak. Once the metal has cooled, it condenses, and the leaks typically stop until the process starts over again.

Malfunctioning Temperature and Pressure Relief Valve

Water heaters are equipped with a temperature and pressure relief (TPR) valve. The purpose of this component is to release pressure buildup from within the tank if its temperature or pressure becomes too high. This prevents explosions.

Rust, corrosion, and mineral buildup cause TPR valves to malfunction, which causes leaks or a failure to function. When the TPR valve is unable to function, the tank’s water may exceed the boiling point and convert into steam. Steam builds up within the tank and has the potential to dislodge the tank and propel it, causing major property damage and potential injuries.
