The water is hot inside your tank, so when it leaks out it can create a sizzling sound as it hits a cooler surface. Contact a professional ASAP if you hear this sound.
Secondly, can a water heater explode?
There are a number of reasons that your water heater can explode; however, the main reason behind water heater explosions is pressure. Anything that causes excess pressure on your water heating system, such as a poor anode rod, or a lot of sediment buildup, can all cause your water heater to explode.
Furthermore, how do I stop my water heater from making noise? 1. Fix a rumbling or knocking sound in a hot water tank by flushing out the debris gathered in the bottom of the tank. If your tank is fuel-powered, set the gas control on pilot setting. If it is electric-powered, shut off the circuit breaker that powers the tank.
Similarly, why does my water heater sound like a kettle?
The Most Common Cause of Kettling
What’s probably happening isn’t boiling water, but water bubbling up through a layer of sediment at the bottom of the water heater tank. Sediment can build up in a tank because of a high amount of hard water minerals dissolved in the water supply.
