How to Get Sediment Out of Water Heater?

Why Sediment Buildup is a Common Problem in Washington Homes

If your hot water suddenly feels inconsistent or your system makes odd popping sounds, you may need to learn how to get sediment out of your water heater properly. Over time, minerals in your water form layers of sediment at the bottom of your water heater tank, especially in areas with hard water like Kitsap County, Gig Harbor, and Tacoma.

This buildup restricts water flow, damages the heater tank, and reduces energy efficiency. Knowing how to get sediment out of your water heater ensures your system delivers consistent performance and helps prevent costly plumbing repair needs later on.

That’s why Pelican Plumbing offers professional heater flush and maintenance services to help Washington homeowners maintain their water heater tanks safely and effectively.

What Causes Sediment Buildup in a Water Heater?

Sediment buildup happens when dissolved minerals mainly calcium and magnesium fall out of hot water as it’s heated. The particles settle at the tank’s bottom, forming layers that trap heat.

As a result, the gas burner or heating elements must work harder to warm the tank water, wasting energy and shortening the heater’s lifespan.

Differences Between Gas and Electric Heaters

• Gas water heaters often make crackling or rumbling noises as sediment interacts with the gas flame beneath the tank.

• Electric heaters may experience burnt-out elements when sediment coats the heating rods.

What Does Sediment Look Like?

Sediment may appear as sandy grains, white flakes, or dark residue that clogs the drain valve. It’s a key sign that your system needs a heater flush or water filter installation to keep the system clean and prevent future buildup.

What Are the Signs of Sediment in a Water Heater?

Here are some clear indicators that your water heater tank may be filled with sediment:

• Rumbling or popping sounds during heating cycles

• Reduced hot water supply or fluctuating temperatures

• Cloudy or rusty water from the faucet

• Rising energy bills or slower water heating times

• Early shutdowns or short cycling

Ignoring these signs can cause more severe plumbing service needs or even tank failure. Learning how to get sediment out of water heater units early can save you time, money, and energy.

How to Get Sediment Out of a Water Heater (Step-by-Step Guide)

If you want to know how to get sediment out of your water heater safely, follow this guide using basic tools like a garden hose, brass drain valve, and wrench.

Step 1: Turn Off Power and Water Supply

• For gas systems, turn the control to “pilot.”

• For electric heaters, flip the breaker off.

• Shut off the cold water supply line feeding the heater tank.

Step 2: Connect a Hose to the Drain Valve

Attach a garden hose to the brass drain valve near the tank’s base. Place the other end of the hose outside or in a floor drain for proper discharge.

Step 3: Drain the Tank Completely

Open the pressure relief valve to release trapped air, then open the drain valve to let the tank water flow out. This removes most of the loose sediment inside.

Step 4: Flush Remaining Sediment with Cold Water

Close the drain valve, briefly reopen the cold water supply for 30–60 seconds, then drain again. Repeat until the water runs clear. This flushing process clears debris and extends heater life.

Step 5: Inspect the Anode Rod

Remove and inspect the anode rod. If it’s corroded or coated with buildup, replace it to prevent faster sediment accumulation and corrosion within the heater tank.

Step 6: Refill and Restore Power

Close all valves, remove the garden hose, and turn on a hot faucet inside the house to release trapped air. Once the tank water flows smoothly, restore power or relight the gas pilot.

Following these steps ensures your water heater operates efficiently and helps you understand how to get sediment out of water heater systems in a safe, simple way.

How Often Should You Flush Your Hot Water Heater in Washington?

Homeowners in Kitsap County, Gig Harbor, and Tacoma should perform a full heater flush at least once a year. In areas with extremely hard water, twice per year is ideal.

A consistent flushing schedule ensures:

• Lower utility bills

• Reduced strain on the gas burner or heating elements

• Longer water heater lifespan

• Better water quality overall

If you have a water filter system installed, it can slow down sediment buildup and extend the time between maintenance sessions.

How Much Does It Cost to Flush a Water Heater in Washington?

The average cost for a professional water heater flush in Washington ranges from 100–200. Prices vary depending on:

• Tank size and type (gas or electric)

• The amount of sediment buildup

• Accessibility and location of the heater tank

While DIY methods using a garden hose and drain valve work for minor cleanings, hiring a professional plumber ensures a complete flushing service with inspection and safety checks.

If you’re unsure how to get sediment out of your water heater properly, it’s always safer to call a professional who can flush your water heater tank without causing leaks or damage.

Can You Prevent Sediment Buildup?

Use of Water Softeners or Filtration Systems

Installing a water filter or softener can help reduce mineral content before it enters the heater tank, lowering the risk of sediment buildup.

Regular Inspection and Maintenance

Schedule yearly plumbing service to inspect the drain valve, gas burner, and other key components. If you hear unusual sounds or see discolored water, call a licensed technician for a repair or detailed flush.
