Replacing hot tub pumps is not a difficult job. Here are a few steps that can help guide you through the process.

Step 1 - Prepare the Area

The first thing that you need to do is unplug all of the connections. First, remove the electrical cord by unplugging it from the wall. Then, unscrew the water supply from the hot tub to remove it. Then, you will need to remove the panel that is covering the pump. It is typically on the lower area of the hot tub. Use a screwdriver to unscrew it and then move the panel to the side as you work.

Step 2 - Remove Old Pump

Once you have taken the panel off, locate the pump inside. You will want to find the control system and remove the wire that is connecting the ground terminal to the pump. This wire should be a bare copper wire and pretty easy to spot. Next you will want to put down a towel where you are working and a bucket to catch any water that is going to come out. You will need to disconnect the pump's unions. Then, use a screw driver to remove the screws on the base of the pump that are helping to mount it. You can now disconnect from the control system as you are taking the pump out of the hot tub.

Step 3 - Install New Pump

Now that the old pump has been removed, you can begin installing the new pump in reverse. You may want to bring the old pump in when buying a new one in the store, or take a look at it when you are ordering one online to make sure that you are getting the right one for your hot tub. You can find a wide selection on the Internet for a great price if you can take the time out for delivery and processing. Begin by connecting the new pump to the control system. Then, mount the pump and use the screws to secure the base. Then, connect the pump's unions again and reattach the copper wire from the ground terminal to the pump.

Step 4 - Reconnect and Test

Once you have gotten everything hooked up the way it should be, use a screwdriver to reattach the cover panel on the hot tub. Then, turn on the water and then the electricity by screwing the water supply back in and then plugging in the power cord. You can now test out the pump to make sure that it is working properly.

You will want to keep an eye on it for a few days to see that everything is working smoothly. If you experience any problems, open the cover panel again and make sure that each of the wires and connections are tight and secure. Be sure that each time you go in to work on the pump that you are disconnecting the water and power supplies.
