Causes of a Whistling Water Heater

Your water heater works hard to make sure you always have access to a hot shower when you want one. However, since the water heater works quietly behind the scenes, you might forget about it for years. Then you start hearing whistling sounds coming from the water heater and become concerned.

Read on for four possible reasons why your water heater is making this noise and help deciding whether you need to call a plumber.

Why Is My Water Heater Whistling? 4 Common Causes

1. TPR Valve

As your water heater works, heat and pressure build up inside the tank. Under normal conditions, the pressure never builds to a dangerous level. In case it ever does, the temperature pressure relief (TPR) valve opens slightly to allow pressure to escape the tank. This is a safety measure that prevents your water heater from posing a threat to your home, and it’s the most likely reason your water heater is whistling.

2. Drain Valve

Near the bottom of every water heater tank is another valve. This valve exists so you can periodically drain sediment that builds up on the bottom of the tank. If the valve isn’t closed tightly, it could allow air to pass inside and cause a whistling sound.

3. Water Inlet and Outlet

On top of the tank is a cold water inlet and hot water outlet. Over time, the connections here may wear out, especially on the hot outlet side. If the whistling noise is most prominent while you’re running hot water, this is a likely source.

4. Cracked tank

It’s also possible the tank has rusted through and formed a crack, allowing air to blow in or out and create the sound you’re hearing.

Water Heater Repair in Central Jersey

No matter the cause, a whistling water heater deserves attention. Turn off the appliance and check that all connections are tight. Also, look for any rust that could signify a crack in the tank. If everything seems in order but the water heater continues to whistle when you turn it back on, the tank is probably overheating and causing the TPR valve to open and release pressure. This could be dangerous over time, so call an experienced central New Jersey plumber to take a look.
