5 Common Water Heater Problems and How to Fix Them

Dec 3, 2021 | Water Heater Installation

Water heaters are a big part of our everyday lives. We need hot water to wash the dishes, take a shower, and do laundry. It’s so frequently used that it may break down from time to time.

We have made a list of the most common issues encountered with water heaters and instructions on how to remedy them.

Unable to Change Temperature

If your water heater does not respond when the temperature is changed, this indicates that the thermostat has failed. Find certified plumbing or heating professionals in your region as soon as possible to repair or replace your outdated thermostat.

Very Little to No Hot or Warm Water

If you have an electric water heater in your house, the most common reason for the lack of warm water is a faulty heating element, which may be repaired or replaced. The heating element in the tank is in charge of heating the entering water. 

After a heating element starts to fail, you will have little to no hot water to use for bathing, cleaning, or doing laundry once the problem is identified.

Producing Warm Water Takes a Long Time

Once your water tank is completely depleted, it should not take more than a couple of minutes to refill it with warm water again. If it takes an hour or more for you to obtain warm water from your water heater, this indicates that the burner orifice has been contaminated. 

Increasing the gas pressure in your boiling water heater will help you get more hot water when you have a shortage. To get immediate help with this water heater issue, call a professional technician in your region who is familiar with the situation.

In-Line Valve Is Faulty or Damaged

A faulty in-line valve is one of the most common causes of water tank leaks. This is a handle positioned at the top of the tank and is designed to be used to activate or deactivate the flow of water in the tank. 

To resolve this issue, you will need to tighten the nut that keeps the ball or in-line valve in its position. You’ll need to visit your neighborhood hardware store to purchase a replacement in-line valve if the leak gets more severe after being tightened to the proper tightening tension.

Pressure Relief Valve Is Broken 

The majority of water heaters are fitted with a pressure relief valve designed to release pressure from the water tank if the pressure within the tank becomes excessive. If the valve on the top of your water heater starts to leak, we suggest that you replace it either online or at a local shop as soon as possible. 

A pressure relief valve is easily removed and replaced, and the procedure is straightforward.


Having a functional water heater in your house is essential because you use it every day for bathing and cleaning dishes, clothes, and more. When your water heater fails, you might be in for a load of trouble. An annual inspection by a trained specialist is necessary to ensure that water heaters are working efficiently.
