loud how water heater

One of the most common complaints we hear from home owners is about their loud hot water heater! There are many unusual noises that your hot water heater can make, ranging from popping and rumbling sounds to knocking, hissing and clicking noises.

Fortunately, there are many DIY tips you can use to help quiet your loud hot water heater and reduce those annoying sounds. Try the following to eliminate the noise, but remember that regular hot water heater maintenance and repair is key to preventing many of these sounds in the first place!

  • Cracking or popping sounds can usually be addressed by flushing your water heater. A buildup of sediment at the bottom of your water heater can trap water beneath it and as this water heats up, it forces its way through the sediment, resulting in a cracking or popping sound.
  • Knocking and banging sounds are often caused by pipes heating up internally. This noise is commonly referred to as “water hammering” and can be one of the most annoying sounds for home owners. While this does not damage your water heater, it can be quieted by installing a water hammer arrestor at the shut off valves of fixtures like your washing machine.
  • A humming noise coming from your electric water heater is normal, but if it comes on suddenly or is very loud, you should call a professional for assistance. To address minor humming sounds, you can tighten the heating element in your water heater (don’t overtighten) to prevent vibrations.
  • Screeching noises from you water heater can be caused by water under pressure being forced through or around an object. Typically, this noise is made when a shutoff valve is not completely open. Check the valve at your water heater, or at other fixtures in your home to ensure they are all completely open.
  • Hissing sounds can occur after you have used a large amount of hot water, such as after a bath or shower or running the dishwasher on a heavy cycle. When hot water is used up, cold water re-enters the tank and can cause condensation to form on the outside of the tank. As this condensation drips down and hits hot parts of the water heater around the burner, you will hear a hissing sound. If this happens frequently, you may have an undersized water heater that does not meet your household’s needs.

Fixing a Leaking Hot Water Heater Pressure Relief Valve

No comments

how water heater pressure

Your hot water heater pressure relief valve is an important component of both electric and gas hot water heaters. This valve is designed to allow water and steam to escape from the tank if the temperature gets too hot or if pressure gets too high, releasing some of the pressure before a dangerous explosion can occur.

While it is a critical safety feature, a leaking hot water heater pressure relief valve can be cause for concern. If you have noticed a leak from your water heater’s pressure relief valve, you can troubleshoot the issue yourself in a few ways:

  1. Check the Temperature

The temperature of your hot water heater could be causing the temperature and pressure relief valve to do its job, resulting in a small discharge of steam or water. Check the thermostat to determine the temperature setting of your water heater and verify this temperature by running hot water at a fixture until it gets hot. Use a meat thermometer to read the actual temperature of this water, ensuring that it is set at a safe 120 degrees Fahrenheit or lower.

  1. Test the Valve
    Ensure that the valve is functioning properly by lifting the arm on the top of the valve and seeing if water comes out. When you release the valve, it should shut immediately and stop the flow of water. If the arm does not lift and does not snap back down immediately, it should be replaced. There may be debris or rust preventing the pressure relief valve from functioning correctly.
  2. Replace the Valve
    Sometimes your leaking hot water pressure relief valve can be fixed simply by replacing the valve. This easy task requires you to drain the tank to a level below the valve, then opening it to release any residual pressure. The valve can then be removed slowly using a wrench to turn it counter-clockwise. Replace the valve with one of the same pressure rating by screwing it in clockwise and tightening it with a wrench.
  1. It’s Still Leaking
    If you replace the valve and it still continues to leak, this signals a greater problem. A frequently triggered valve means that your hot water heater is consistently overheating your water or building up too much pressure within the tank. It’s best to call in a professional to determine why your water heater is getting too hot or pressure is getting too high so it can be repaired or replaced if necessary.

What Causes a Water Heater Rumbling Noise?

No comments

water heater rumbling noice

If you’re hearing a water heater rumbling sound, you might be concerned that you’ll soon be out of hot water. You’re not sure if your water heater is functioning correctly and don’t know if it needs repair.

A rumbling noise coming from your water heater can be scary, but keep in mind that it may be caused by a number of things, ranging from minor annoyances to issues that require more significant repairs.

In any case, if your water heater rumbling noise has you worried, read on to discover some of the most common reasons for this type of sound.

Hard Water
If you have hard water in your home, hard water scale can accumulate inside your water heater’s tank. This can cause your hot water heater to overheat and make a rumbling sound. If this is the case, consider installing a water softener or whole-home water filtration system to reduce scale build-up.

Sediment Build-Up

As the water inside your hot water tank warms and expands, it moves through any sediment build-up that might have formed within your tank over the years, such as rust or other minerals. This layer of sediment traps water underneath it, where the water heats and bubbles up until it bursts through the sediment. As the boiling water escapes the layer of sediment, it creates the rumbling-like sound that you hear.

Beyond the annoying rumbling sound, these types of build-up can cause future issues with your equipment. Though hard water and sediment build-up are not immediately dangerous, over time they can cause your hot water heater’s tank to deteriorate until it eventually requires complete replacement. Additionally, any sediment built up inside the tank reduces the heat transfer inside, meaning that your water heater’s burner must work harder to produce hot water at your desired temperature. This decreases the efficiency of your unit and increases your energy bills.

To resolve your rumbling water heater problem, you can drain your hot water heater to remove the sediment. It is possible to flush the tank yourself, or you can call in a pro to do it for you quickly and safely if you are uncomfortable taking this on as a DIY task.

If you cannot diagnose your water heater rumbling noise, we recommend that you get in touch with an experienced emergency water heater repair professional to examine your hot water heater. Luckily, Evam Canada is on-call to solve any hot water heater problems.
