Your water heater is making a banging / knocking noise. This is likely due to mineral deposits, or sediment, that has gathered at the bottom of the tank. This is known as “scaling” which is often caused by hard water.

If you happen to live in an area that has hard water, your water heater may experience problems such as banging or knocking noises. When water that has too much magnesium and calcium (like hard water) builds up in your pipes or fixtures it could lead to corrosion which will damage equipment such as tanks used on heating units– causing them go bad quicker than they should!

How Do I Stop My Water Heater From Knocking?

There are a few ways to deal with scale:

  • Use a water softener to reduce the amount of minerals in the water
  • Drain and clean the tank on a regular basis
  • Install a water filter to remove scale-causing minerals before they enter the appliance
  • Adjust the water heater’s temperature to discourage scale build-up –

Whichever method you choose, it is important to keep an eye on your water heater and be proactive in preventing problems!

If none of these solutions work, it may be time to replace your water heater.

How Do You Know If Your Water Heater Is Going To Explode?

No one wants to deal with a water heater explosion, but if it’s going to happen, you at least want to be prepared. So, how do you know if your water heater is going to explode? Here are a few signs that it might be time for a replacement.

  1. If your home has a gas powered water heater and you smell gas near your water heater (smells like rotten eggs or sulfer) then that may be a very good sign that your water heater is just about to explode.
  2. Your water heater is more than 10 years old. Water heaters typically have a lifespan of 10-12 years, so if yours is older than that, it may be time for a replacement.
  3. You hear a continuous barrage of popping (light knocking) noises coming from your water heater. This is an indication that something is wrong and needs to be looked at by a professional immediately.
  4. Your water heater tank is leaking from the bottom. This is normally due to rust, corrosion, deterioration of the tank and should mean that you need a new hot water tank immediately.
  5. You see rust around the water heater. If you notice rust anywhere on your water heater, this is a sign that it needs to be replaced before anything happens.

If any of these signs sound familiar, it might be time to replace your water heater. Contact a professional plumber to get started.
