Water heaters are heavy, and placing one in a drain pan can be a challenging task. Before attempting to place a water heater in a drain pan, it is important to ensure that the water heater is turned off and that the water and electricity supply to the heater is shut off. Detach all pipes and earthquake straps connected to the heater. It is also important to have the right equipment, such as a jack, straps, and a helper to assist with lifting the heater. The heater should be drained of water to make it lighter and easier to lift. Once the heater is lifted, the drain pan can be slid underneath, ensuring that the drain opening is oriented correctly. The heater can then be lowered onto the pan and the pipes reattached.

What You'll Learn

Ensure the water heater is empty
To ensure that your water heater is empty, start by turning off the water supply. If your heater is electric, cut the power supply as well. If it works on gas, make sure to turn off the gas supply. Now, detach the pipes attached to the heater. You will need to drain the hot water stored in the water heater. Be cautious as the water may be hot.
An empty 40-gallon water heater weighs about 125 lbs, whereas a gallon of water weighs 8 lbs. So, a full 40-gallon water heater weighs about 445 lbs. Therefore, it will take some help to lift the heater, but it will be much lighter without the water in it.

Use a jack to lift the heater
To place a water heater in a drain pan, you will need to lift the heater. This can be done in several ways, but one of the most effective ways is to use a jack. Here is a step-by-step guide on how to use a jack to lift the water heater:
First, ensure you have the correct equipment. You will need a jack, a ratchet strap, cardboard, and a short 2x4 piece of wood. Place the jack in a position where you can still slide the drain pan in. Loop the ratchet strap under the backside of the water heater and over the lift part of the jack, around the outside of the jack post. Pull the jack post towards the water heater. Place the cardboard between the jack post and the water heater jacket to protect the heater from damage. Then, place the short 2x4 below the jack lift to space the water heater away from the jack.
Now, you can start to lift the heater. Slowly jack up the heater, watching the ratchet strap for any signs of strain or issues. Ensure that the strap is not putting pressure on the drain valve or any other components of the water heater that could be damaged. Once the heater is lifted about 3 inches off the ground, you can slide the drain pan into position. Remember to orient the drain opening of the pan with the water heater.
After the drain pan is in place, slowly lower the water heater by lowering the jack. Remove the jack and any supporting equipment. Ensure that the water heater is stable and secure in its new position on the drain pan.
Using a jack to lift the water heater can be a safe and effective method, but it is important to work carefully and slowly to avoid any damage to the water heater or surrounding areas. It may also be helpful to have an assistant to guide the drain pan into position while you operate the jack.

Slide the pan underneath
Before sliding the pan underneath the water heater, there are a few preparatory steps to take. First, cut the electric supply to the water heater and, if it works on gas, turn off the gas supply as well. Then, shut off the water supply by locating the water pipe and turning it off. Detach the pipes attached to the heater before removing the water heater drain pan. Earthquake straps that are connected to the heater should also be removed.
Now, drain the hot water that might be stored in the water heater. This water could be hot, so be careful while draining it out. The heater will be lighter without 200 lbs of water in it, making it easier to handle. If the tank is connected to the water supply pipes with flexible hoses, it will be easier to raise the tank and slide the pan underneath.
If you are working with a partner, you can bear-hug the heater and lift it just enough for your partner to slide the pan underneath. If you are working alone, you can set the tray right next to the water heater, lift it, and slide it under with your foot. Alternatively, you can use a belt or strap to wrap around the heater and give you better leverage when lifting.
Once the pan is in place, ensure that the drain opening is oriented correctly with where you want it in reference to the water heater, not the floor. If you need to rotate the water heater, the pan will likely rotate with it.

Rotate the heater to align with the pan's drain opening
Before rotating the heater, ensure that you have cut the electric supply to the water heater. If your heater works on gas, make sure to turn off the gas supply as well. It is also important to shut off the water supply to the water heater.
Now, to rotate the heater to align with the pan's drain opening, you will need to first lift the heater. This can be done by slowly jacking up the heater with a jack and using a strap to support it. Ensure that the strap does not put pressure on the drain valve or any other components of the water heater that could potentially cause damage. Once the heater is lifted, you can then rotate it so that it aligns with the pan's drain opening. Make sure that the pan is positioned correctly with the drain opening oriented in the right direction.
If you are unable to lift the heater due to plumbing or soldered copper pipes, an alternative method is to use an oversized water heater pan. Cut the pan in half and overlap the halves, sealing the seams and edges with silicone or adhesive. Screw the pan down to the floor if needed. However, note that this method may not be as effective as lifting the heater and sliding the pan underneath.
Additionally, consider the weight of the water heater, especially if it is a gas heater. Gas heaters are heavier due to the water inside, so it is recommended to drain the water to make lifting and rotating the heater easier. You may also need assistance from another person to safely lift and rotate the heater.
Lastly, be cautious when working with gas heaters as they can be dangerous. It is advised to hire a professional or seek advice from a pro to ensure the safe rotation and positioning of your water heater.

Rock the heater to ensure stability
Once you have placed your water heater on the drain pan, it is important to rock the heater gently to ensure stability. This step is crucial to prevent leaks and enhance the effectiveness of the pan. A stable water heater reduces the risk of leaks.
To do this, gently rock the water heater back and forth to check if it is stable on the drain pan. If the heater wobbles, you can adjust the position of the pan or add shims under the heater to level it properly.
Rocking the heater will help you ensure that the heater is stable and secure on the pan. This simple step can help you avoid potential leaks and water damage, which can be costly and time-consuming to repair.
If you are installing a new water heater, make sure the heater is elevated securely before placing it on the drain pan. After positioning the heater, gently rock it back and forth to test its stability.
For existing water heaters, it is best to drain the water and detach the pipes before attempting to move the heater or install a drain pan. This process can be challenging, and it may require multiple people to lift the heater and slide the pan underneath.
