What You Will Need to Follow This Tutorial
● Bucket or container
This will be the receiver of the water that you’ll be draining out from the heater tank, so make sure that it has the right capacity for the water volume inside the tank. If you don’t have a single large container, it’s okay to use multiple buckets. Preferably, your container would be easy to transport to where you’ll be disposing or storing the collected water.
● Hose pipe
You can use a garden hose for this requirement. A hose pipe will be used to connect to the tank outlet to let the water out into the bucket or container you prepared.
● Adjustable Wrench
This will help you loosen your drain valve when removing it.
● Manual drill / Hacksaw blade / Serrated Insert
These tools will let you make an opening for draining in case of a defective drain valve. It depends, however, on the material your drain valve is made of.
A serrated insert can be used for plastic drain valves, while a hacksaw blade is suitable for brass or metal valves. If none of this works, you can use a manual drill.
In case you use a hacksaw blade for your valve, you’ll need a large screwdriver to finish the job.
● Rug (optional)
Your debacle may cause some spills so a rug can be handy to keep things from going messy.
Step 1: Turn off The Water Heater
Since you’ll be flushing out a water heater, you’d want to avoid the danger of burning yourself from the hot water from the tank. So, you’ll have to turn off the heater’s power supply either through the circuit breaker or gas line depending on the kind of water heater you have.
I would also recommend letting the water cool down for a while before proceeding. Moreover, you can open a hot water faucet to reduce the hot water and check the temperature.
Step 2: Switch off The Water Source And Open Faucets
Once you’ve deemed that the water in the tank is cool enough for you to work on the heater, turn off the cold water source. Open a hot water tap to let in air and relieve pressure in the system.
Step 3: Take off The Faulty Drain Valve
For a brass valve, you can use an adjustable wrench to remove the valve. If this does not work, use a hacksaw blade to make a cross cut which you can then use a screwdriver to unscrew.
For plastic drain valves, use a serrated insert on the nipple to unscrew. If you have a manual drill, you can opt to create a hole on the drain valve.
Pro tip: DO NOT use electric drills when working with equipment that involves water to avoid electrocution.
Step 4: Attach Hose Pipe And Let The Water Drain
Once you’ve successfully made an opening to let the water out, attach your garden hose or any hose pipe and make sure the other end goes to a drain or your prepared container. You may place a rug underneath the valve to catch any spills. Let the water completely drain.
In case no water comes out, this may mean your drain is clogged due to the build up of sediments. To fix this, attach the other end of the hose pipe to a nearby faucet. Open the faucet and let the backwash remove the clog.
