Common Water Heater Repairs: An Insightful Overview

Posted on

Water heaters, indispensable in modern households, are responsible for providing all of the hot water that you need. Given their regular use, it's no surprise that they might falter occasionally. Understanding common repairs associated with water heaters can help homeowners address issues promptly and make informed decisions.

Temperature Inconsistencies

One of the most frequent complaints with water heaters is inconsistent water temperature. This can be due to a malfunctioning thermostat or a broken heating element. 

Electric water heaters usually have two elements, and if one fails, you might get lukewarm water. In gas water heaters, the burner assembly or the gas control valve might be at fault. Repairs can involve replacing the faulty components or resetting the thermostat.

Water Leaks

Discovering a puddle of water beneath your heater is a clear indication of a leak. Leaks can be caused by a range of factors:

  • A loose drain valve can be tightened to resolve minor dripping.
  • Too much pressure inside the tank might force the temperature and pressure relief valve to release excess water.

However, if the tank itself is leaking, it's often a sign of internal corrosion and typically necessitates a full replacement. Understanding the root cause of a leak is crucial to determine the appropriate repair or replacement actions.

Discolored or Odorous Water

If the hot water from your tap is rusty or carries an unpleasant odor, the culprit might be a corroding anode rod inside the tank. This rod attracts corrosive elements, safeguarding the tank. But over time, it degrades and needs replacing. 

Swapping out the old anode rod for a new one can solve this issue. Regularly checking water quality can help detect and address such issues early.

Noisy Operations

Popping, rumbling, or cracking noises emanating from a water heater is a sign of sediment buildup at the bottom. As the heater warms the water, it also heats the sediment, causing water trapped within it to boil and produce disruptive sounds.

Draining the tank and flushing out the sediment is a typical repair method. Maintaining a routine of periodic flushes can help avoid the buildup and associated noises.

Non-functioning Pilot Light (For Gas Heaters)

A pilot light that won't stay lit can be troublesome for gas water heaters. 

This could be due to a faulty thermocouple, which monitors the pilot light and signals the gas valve to continue gas supply. Replacing the thermocouple is a standard fix for this issue. Ensuring the pilot light remains functional is vital for the heater's consistent performance.
