Talking About Preventative Plumbing Services

Hey there, my name is Russell Tyson. I am going to use this site to educate my readers about services offered by plumbing professionals. When I first started my company, I was unaware of all the necessary plumbing procedures needed to keep the toilets from backing up. My clients often failed to notify me when a toilet started to fail, likely due to embarrassment or a lack of time. Luckily, I was clued into the value of hiring plumbers to perform regular maintenance and repairs on the toilets to keep them in fine shape. I hope to detail those services on this site to inspire others to embrace preventative plumbing procedures.

How To Deal With Water Heater Humming Sounds

by Charlie Clarke

If you have a water heater and are serious about maintenance, then you may understand that you need to listen closely for sounds that may indicate the appliance is failing or in need of repair. While both knocking and banging noises may be troubling, there are some sounds that are not nearly as troubling. Humming is one of these noises, and there are some fairly easy ways that you can stop the noise. 

Tighten The Heating Elements

As water enters and leaves your water heater, it moves around inside the tank and causes turbulence. This also happens as the cold water drops to the bottom of the tank and the warm water rises. If your heating elements are not tight and secure, then the vibration of the elements may cause the humming noises. Try tightening them to see if the noise stops. 

You can tighten the elements in a few different ways depending on how loose they are. If the elements are just a bit loose, then you can use a crescent wrench to do the tightening. Open the wrench and slip it over the flat octagonal metal parts of the element. Turn the wrench to the right to tighten it. If the element moves more than one-eighth to one-quarter of an inch, then you will need to use a socket wrench to complete the tightening instead. This requires the removal and the replacement of the electrical wires attached to the element. Make sure to turn off the electricity to the unit before detaching and attaching the wires. 

Tighten The Wire Mount Screws

Heating elements and thermostats are connected to the electrical wiring of the water heater with the assistance of screws. These screws allow electrical power to move through the exposed wires and into the parts of the appliance. When the screws are not tightened enough, they can vibrate as electrical energy surges through the wiring. 

Tightening the screws will often stop the vibration issue. Start by shutting off the power and removing the control panel that sits over the wired thermostats and the heating elements. When you are done, use a multimeter to make sure that electricity is no longer running through the wires. If it is safe, then use a Phillips screwdriver to tighten each wire attachment screw. You want the screws hand-tightened, but not so tight that they place significant pressure on the wires. 

When you are done, turn the power back on to see if the humming noise has stopped. If it hasn't, reach out to professionals at companies like Walt's Plumbing for more tips.
