Water Heater Noises and What They Mean

Are you hearing strange noises coming from your water heater? Well, it’s not really uncommon for water heaters to make certain noises while they’re running, but some sounds could indicate a bigger problem. Our experts at Optimal Plumbing Solutions have years of experience providing water heater repair in Clayton, NC, and we’re more than happy to share what your appliance could be telling you.

Popping Sounds

These are often attributed to excess sediment in your water heater tank. Minerals in the water can build up and harden over time, making your water heater work harder than it needs to. This can slow things down and cause damage. Sediment buildup can be avoided by performing regular water heater maintenance, including flushing the tank and checking if the anode rod needs to be replaced.

Humming

Humming noises could mean that the heating element might be loose. This can make it difficult for the water heater to maintain its temperature. You should have a professional inspect your water heater to make sure the heating element is properly connected and secured.

Hissing Sounds

These could indicate a leak in the water heater, which should be addressed immediately. Check the appliance for signs of corrosion or damage, and call a professional plumber if you suspect a leak.

Whistling

Whistling noises commonly have something to do with the pressure relief valve. This valve helps regulate the pressure in your hot water tank, and it may need to be adjusted or replaced if you’re hearing a whistling sound. This must be taken care of as soon as possible to avoid further damage to your water heater.

If you hear any of these sounds from your water heater, Optimal Plumbing Solutions can help you understand them better and address potential issues with your appliance. Whether you need simple repairs or complete water heater replacement, we are the local team you can trust.
