When it comes to keeping down the operational costs of keeping a pool down, solar pumps are a great way to do that. Running a pool during the summer can increase an energy bill by a considerable amount from the pump operating. Solar pumps do not tap into the electrical grid of your home, resulting in a decrease in the energy bill. After a few years of use, you may find yourself in the position of having to replace the solar pump. Here are some steps to take to do that quickly and easily.

Step 1: Remove Wires from Battery

Before you start to do any work on the solar pump, you will want to disconnect the wires that are running to the battery. This will keep you safe as you work with the pump.

Step 2: Plug Hoses

As you get ready to replace the solar pump that circulates the water in your pool, you will want to make sure that you plug up both the inlet and the outlet hoses. By doing this now you will make sure that you do not forget later. Once you remove the hose from the pump, gallons of water will start to pour out onto your patio, your deck, or your landscape. Most pools have a small rubber stopper that is used for this purpose. If not, cover the holes with a rubber plug the same size as the opening.

Step 3: Remove Hoses from Pump

There are two hoses that are connected to the solar pump. There is an inlet hose that is usually on the bottom and going into a filter. Another hose, which is the outlet hose, is coming out of the top of the pump. They are easily removed with the use of a screwdriver or a small wrench depending on the fastener type.

Have a bucket handy as you remove each hose to let the water that is captured in the hose drain without spilling all over the ground.

Step 4: Remove Pump

With the wires disconnected, and the hoses removed from the pump, you can now pick up the old pump and make way for the new. Since these pumps may be heavy, a wheelbarrow, tractor cart, or a friend will make this job much easier. Lift the pump out of the area and dispose of it properly.

Step 5: Install New Pump

Set the new solar pump into the same area as the old one. Check to make sure that it sits level. If not, install some blocks under the pump and level with gravel, shims, or sand. Connect the hoses to the correct positions according to how they were on the old one.

Step 6: Prime Pump

With the new pump into place, remove the rubber plugs in the hoses to get the water moving again. Reconnect the wires to the battery terminals and turn the pump on. A self-priming pump will automatically start to suck the water into the filter and start to pump it out. This should only take a few minutes to get a smooth flow to the water. If not, turn the pump off and wait a few minutes before turning it back on again.
