Your hot water heater can make a lot of noises. We’ve gotten calls about clanging, banging, knocking, thumping, whistling and a lot more. But, we recently got a call for a hot water heater in Ripon that was making a humming sound.
We’re not talking about a pleasant, musical hum – it was more like a lawn mower.
If your water heater is making a humming noise like that, read on.
Possible Causes for a Humming Water Heater
Obviously, we can’t diagnose your issue without having a good look at your water heater. But, we can tell you what we check for first when we hear someone complaining about a humming water heater. Some of these you might be able to check yourself, but for many you’ll want to call your local plumbing technician to have a professional’s help.
1. Gas Line
Check to make sure the gas line is properly fitted. If it is bent, blocked, or the wrong size, this is one possible source of your water heater humming.
2. Flex Connector
The flex connector or flex line should also be inspected. When you water heater kicks in, there is a temporary drop in pressure, and if your flex connector isn’t properly fitted, this can cause your annoying humming sound.
Does your water heater have adequate space on all sides? Make sure there is ample clearance, and that no outside objects are touching the unit.
