What Do I Need To Get Started?

In order to properly dispose of any fuel/oil that may be stuck in the internal combustion portion of a water heater or even the water heater itself, there are some simple procedures to follow.

1. Open the tank cap

Get some compressed air and remove the water heater tank cap.

2. Find the drain hole

Reach inside the tank opening and check the drain hole for any signs of corrosion or sediment. If you see either then remove the tank drain cover.

3. Locate the flushing button

Once you have determined where the tank drain hole is, use a tool called a side-vent clog remover to remove the blockage. Be sure to be gentle when pulling the plug.

4. Push the plug back into the drain hole

A heavy-duty utility screwdriver is necessary to push the plastic plug back into the drain hole.

Lay Out Your Tools

Before you begin cleaning your tank water heater, you need to be ready. First of all, you need to have a pump or filter attachment for your vacuum cleaner. You need to have a small container like a bucket with warm water, a towel, a roll of paper towels and the right kind of tank cleaning nozzle for your vacuum cleaner.

Open the Tank

Find the opening in the tank, use your vacuum cleaner to suck up any water trapped inside. Don’t be alarmed if you don’t see any water dripping down as that is simply the way tank water heaters work.

Use the hose to empty the tank, wipe it clean with a towel and make sure you don’t forget to flush the tank with hot water.

Disconnect the Power

Before you begin, make sure that the plug in the tank is unplugged. The electric plug in the tank can get in the way when you are actually flushing, so make sure it is out of the way.

Prepare the Water Heater

The next step is to prepare the water heater for flushing. Depending on the size of the tank you will need to empty a large amount of water into the water heater tank to ensure that the process is properly done.

Open the Tank

Once the water heater has drained, you will need to empty the water to ensure that there is enough for your work. If you are using a gas tank, then you will need to have the tank half-filled with water, otherwise you can use a bucket to collect the water.

How To Use Your New Flushing Kit

The simplest way to do a flushing of a tank is using a needle powered water pump, there are several of these on the market today and they can be purchased easily for about $35, plus another $15 for the pumps water pump impeller. The basic pump uses a very small air pump to move the water. To start the pump, you need to place the tank full of water in the sink, and position a pressure washer over the lower flue of the tank.

Then slowly turn the washer handle until water is started to flow into the tank, then maintain the pressure on the pump to force the water into the tank, turning it as needed.

After the tank has filled with water, turn the pump off and unplug the pump to stop the flow of water.

Fill and Drain the Tank and Drain Line (Without the Pressure Washer)

The inside of your water heater is a closed loop, the outside is a wick. Which means if you don’t keep up with the water, and subsequently the tank, you can eventually have it back up. The most effective way to do this is to clean out all the debris with a pressure washer and fill with fresh water. It’s a way to scrub out some of the stuff that builds up inside the tank, the best part is that it uses much less energy than running the tank dry and refilling it. The downside is that there is a risk that some things might get away, but to save on this you can buy specially made bags and avoid this risk entirely.
