What Are Those Rumbling & Popping Sounds Coming From Your Water Heater in San Antonio?

Imagine this – you’re enjoying a quiet evening at home when suddenly you hear a rumbling or popping sound echoing from your water heater. While it might be disconcerting, it’s not necessarily an immediate cause for alarm, but it does signal a condition that needs attention.

This unusual noise from your water heater is commonly due to the buildup of sediment within the tank. San Antonio, Texas, is well-known for its hard water, with high levels of calcium and magnesium. According to USGS Water Data, San Antonio’s water hardness is about 357 mg/L or 21 gpg, which classifies it as ‘hard’ to ‘very hard’ water. These minerals tend to accumulate at the bottom of your water heater over time, causing the rumbling or popping sounds. Can this harm your water heater? Over time, yes!  It can cause a rupture in your water heater’s tank and eventually it will start leaking. This can be a big deal if your water heater is located in your home’s attic which is the case in a lot of homes in San Antonio!

The Fix: Water Heater Flush

A professional plumber can effectively solve this issue by performing a water heater flush. Here are the steps they would typically follow:

1. Turn off the water heater and the cold water supply: This step ensures safety during the procedure.
2. Connect a garden hose to the drain valve: The other end of the hose should lead to a suitable drainage area.
3. Open the drain valve: This allows the water in the tank to start flowing out through the hose.
4. Open the pressure relief valve: This is done for safety and to allow the water to drain faster.
5. Allow the tank to drain: Depending on the size of your water heater and the amount of sediment, this may take some time.
6. Flush the tank: Once the tank is empty, the plumber will turn on the cold water supply with the drain valve still open to flush out any remaining sediment.
7. Close the drain and pressure relief valves and refill the tank: Finally, the plumber will disconnect the hose, close the valves, and refill the tank, restoring your hot water supply.

Regularly flushing your water heater can extend its lifespan, increase its efficiency, and decrease your energy costs.

Preventive Measures: Water Softener Installation

To prevent recurring sediment buildup and water heater issues, homeowners in San Antonio should consider installing a water softener. This device works by reducing the levels of calcium and magnesium in your water, thus preventing the formation of hard water scale in your water heater and other appliances.
