5 Signs You Need to Flush Your Water Heater

If your water heater has been in service for a few years, consider flushing it. Flushing a water heater can improve its efficiency and extend its lifespan. Below are signs that it’s time to flush your water heater.

1. Rust-Colored Water

Rust is often a sign of corrosion, weakening the walls and bottom of your water heater. If you notice rust-colored water coming from your taps, it’s time to flush the sediment and chemicals that have built up.

2. Decreasing Hot Water Supply

Over time, the sediment and minerals in your water heater can build up. If your hot water runs out faster than it used to, or it’s not as hot as it used to be, it might be due to sediment blocking the heat transfer. Flushing your water heater can help clear this blockage, restoring your hot water supply.

3. Unusually High Energy Bills

No one wants to receive an unexpectedly high energy bill. If your electricity bills increase, it might be due to the sediment and other debris in your water heater. As this debris accumulates, your water heater must work harder to heat the tank, increasing energy costs. A simple flush can improve the efficiency of your water heater and reduce extra expenses on your electric bill.

4. Unusual Noises

If you hear popping, rumbling, or strange noises from your water heater, it may be caused by accumulated sediment in the tank. When these sediments come into contact with the heating elements, they can cause loud and disturbing noises. In this case, flushing your water heater can help reduce the amount of sediment and restore your peace.
