Lancaster, MA Plumbing Question: Why Is My Water Heater Rumbling?

If your water heater rumbles or makes other strange and unusual sounds, it may be an indication that you need professional plumbing repair. Often, the sounds your appliances make are warning signs that something needs to be fixed and it’s important that you heed those symptoms. Not only will repair get your water heater working again, but it may also prevent future repairs and premature replacement.  If your water heater makes too much noise, call Basnett Plumbing & Heating plumbing repair in Lancaster, MA today.

There are several different reasons your water heater makes a rumbling noise:

  • Scale. About 85% of homes in America have hard water. Hard water refers to high levels of calcium and magnesium bicarbonate in your water supply. These deposits tend to build up on the inside of your water heater and on the heating elements. Those deposits are commonly called limescale and often cause problems in your water heater’s tank–including overheating. A professional repair service will likely delime your tank in order to get it working again.
  • Sediment. Silicate and sand can build up on the inside of your water heater. Whether drawn from the main water supply or introduced into the system by pipe leaks underground, sediment can also cause your tank to overheat. It can typically be removed by periodic system flushing. Check with a pro to see what the best course of action for your water heater is.
  • Cold water. If the amount of cold water entering your water heater is excessive, then this can also cause a rumbling sound. If there is a leak around the input valve, this can lower the total temperature of the tank and cause your heater to work more than it needs to. The rumbling noise occurs as a result of cold and hot water mixing together.

Sounds are difficult to diagnose during plumbing repair. Let the Lancaster, MA plumbers at Basnett Plumbing & Heating figure it out for you. We offer exceptional plumbing services for all of your home’s needs. Call us today.
