Importance of Scheduling Water Heater Service

It is imperative that you schedule water heater service as soon as you notice an issue. If you wait too long then you may face major consequences. Waiting to schedule water heater repair can result in:

  • Lower efficiency
  • Higher energy and water bills
  • System failure
  • Problem getting worse
  • Expensive repairs

Sometimes it’s difficult to detect a water heater issue because you aren’t near the actual system. This is why it is important to check on your water heater every once in a while to look for anything strange. You should also take note of any issues with the hot water itself. Here are common signs that you need to schedule water heater repair.

Strange Noises

If you start to hear popping, rumbling or banging coming from your heater then you need to call a plumber. These noises could mean that the heater is just getting too old to work efficiently and needs to be replaced. Popping noises could mean that there is a sediment build up. The noise is caused by the sediment moving around as the water boils in the tank. 

A plumber will be able to quickly identify the cause of strange noises. After they have done this, they may recommend repair, cleaning or full system replacement. Noises coming from the water heater is not something that you should wait to get checked out. The longer that you wait, the worse the problem can get. 

Water Heater Leak or Pooling

A water heater leak can cause major damage if not taken care of right away. Pooling on the ground can cause structural damage, mold growth and more. If you notice a substantial leak, you can turn off the water supply until a plumber can get there. There are a few causes of water heater leaks:

  • Cracks: as metal heats and cools it expands and contracts. This constant movement can cause the metal to crack and leak water.
  • Corrosion: in older water heaters especially, the metal can become rusted and begin to corrode. This can result in holes that will begin to leak water.
  • Connection leak: the leak may be coming from a connection rather than from the heater itself. If the pooling occurs around the water supply line, hoses or valves then it is most likely a connection leak.

If your water heater is cracked or corroded then you will most likely need to replace the entire system. A connection leak is often easy to fix and only requires a component replacement or tightening. 

Contaminated Water

You may notice that your hot water looks different than usual. Here are three common types of contaminated water and their possible causes:

  • Sandy: if you see sand or grit in your water then there is most likely a buildup of sediment in the water heater. 
  • Rusty: if your water develops a reddish tint and a metallic odor and taste, then you could be dealing with rust. Water heaters often develop rust within the tank or in the pipes. 
  • Cloudy: if you notice that your hot water is cloudy and has a strange taste or smell, it could be the result of mineral deposits.

To resolve these issues you will need to call a professional plumber. They will be able to provide a thorough inspection and determine whether the water heater simply needs to be drained or if it requires a repair or replacement. 

Lack of Hot Water

There are many reasons why a water heater may not be heating as effectively as it used to. One of these is sediment buildup. As the sediment settles to the bottom of the tank, it covers the area where the burners are and blocks the heat. It is possible that the burners themselves are malfunctioning and not properly heating the tank. 


To determine exactly what is causing a lack of hot water from your water heater, you will need to contact a plumber. They can provide an inspection and quickly find the root of the problem. 

Temperature and Pressure Relief Valve Issues

When the temperature gets too high in the water heater, the temperature and pressure relief (TPR) valve releases. This helps to bring both the temperature and the pressure down in the water heater. Sometimes, the TPR valve rusts or corrodes over time. This can become dangerous and put your water heater at risk. 


Make sure to test the TPR valve every once in a while by pulling the lever. If the valve does not open and shut as you pull the lever then you need to call a plumber. Typically, the valve can be easily replaced without having to replace the entire system.
