What is a hot water tank?
A hot water tank is an essential home appliance that stores and heats water for use throughout the house. It is typically made of steel or copper and can hold anywhere from 40 to 120 gallons of water. The tank is insulated to keep water hot, even when not in use. The tank usually connects to a cold water supply line and heats the water via a gas or electric heater.
Why do you need to drain a hot water tank?
Over time, sediment, rust, and other debris accumulate at the bottom of your hot water tank. This buildup can cause your water heater to work harder, which means higher energy bills for you. It can also lead to decreased efficiency and ultimately shorten the lifespan of your unit. Draining your hot water tank will remove the sediment and buildup and keep your unit working in tip-top shape.
How often should you drain your hot water tank?
The frequency with which you should drain your hot water tank depends on several factors, such as the size of the unit, the number of people in your household, and the quality of water in your area. Generally, it is recommended to drain your hot water tank at least once a year. However, if your water has high mineral content or is hard, you may need to drain it more often.
What equipment do you need to drain a hot water tank?
Before you begin the process of draining your hot water tank, there are several tools and equipment that you will need to have on hand. The following is a list of essential equipment you need to gather:
| Equipment | Purpose |
|---|---|
| Bucket or hose | To collect drained water |
| Gloves | To protect your hands from hot water and debris |
| Adjustable wrench | To disconnect the water supply |
| Screwdriver | To remove the drain valve |
How Do You Drain a Hot Water Tank?
Now that you have all the necessary equipment, it’s time to start draining your hot water tank. Follow these simple steps:
Step 1: Turn off the power and water supply
Before you start draining your hot water tank, turn off both the power and water supply. If it is a gas water heater, turn the thermostat to the pilot setting. If it is an electric tank, turn off the breaker to the unit. Also, turn off the cold water supply valve that connects your unit to the main water supply.
Step 2: Attach a hose to the drain valve
Locate the drain valve located at the bottom of your hot water tank. Attach one end of the hose to the drain valve, and run it outside or to a nearby drain. If you don’t have a hose, use a bucket to collect the drained water.
Step 3: Open the drain valve
Open the drain valve slowly by turning it counterclockwise with a screwdriver, wrench, or pliers. The water will start to flow out through the hose or bucket. You may also need to open a hot water tap in your house to allow air to enter the tank and let the water flow out more easily.
Step 4: Let the water drain completely
Allow the water to drain out completely until there is no more water coming out of the hose or bucket. You may need to position the hose or bucket to collect any remaining water that may be at the bottom of the tank.
Step 5: Close the drain valve and refill the tank
When the water has drained completely, turn the drain valve clockwise to close it. Remove the hose or bucket and turn on the cold water supply valve to refill the tank. Open a hot water faucet to allow the air to escape and let the tank fill completely before turning on the power or gas to the unit.
Step 6: Turn on the power and water supply
Turn on the power or gas to the unit and turn up the thermostat to the desired temperature. Wait for the water to heat up before using hot water again.
Advantages and Disadvantages of Draining Your Hot Water Tank
Advantages
There are several benefits to regularly draining your hot water tank, including:
