A water heater is a critical aspect of your home’s plumbing system. One sign of potential problems is excess noise. If your water heater is making strange noises, it’s time to have a reputable plumber in Burbank, CA, from LeadingEdge Plumbing & Rooter to check it out.

Popping Noises

This is usually caused by a buildup of residue in the tank. Residue can consist of sand, dirt, and mineral scale. As it builds up inside your tank, it affects the operation of the heater. Our water heater services can include draining and flushing your tank to remove residue.


A rumbling sound coming from your hot water heater is the result of the water heating up and passing through debris in the tank. As the water passes through the dirt, it meets resistance and causes a rumbling noise, resulting in the inefficiency of the heater. While this is not a sure sign that you need a water heater replacement, it is a good idea to get the unit checked out by a professional.


If you hear a sizzling sound coming from your water heater, it is most likely an issue of reduced water flow into the unit. Improper water heater installation, faulty pressure and temperature relief valves, and bent lines may all cause sizzling.


This can be a sign of a faulty or loose heating element. In to element units, if one is loose or failing, the water heats from the top-down, causing the humming. We will recommend a professional inspection to determine if you will need water heater repair in Burbank, CA.

Tankless water heater owners may also experience noisy water heaters. Some noise is common with tankless units, especially during startup. If your heater is noisier than usual, it could be a sign of a water flow issue, a dirty flow valve, or a faulty pressure valve.
