How To Connect a Pump to a Swimming Pool

The heart of your swimming pool filtration system is the pump. You need not change the water in your swimming pool everyday if you have an effective filtration system. What the filtration system does is to continuously pump water from the pool. Water goes through filtering and chemical treatment systems and then back to the pool again. This cycle ensures that your pool is kept clean and bacteria free. Installing a pump for your pool may be done following a few simple steps:

Purchase a pump. Depending on how big your swimming pool is and where you pump will be located, there is a recommended pump size and model that will suit your pool. If you will install your pump above the pool water level, a self-priming pump must be used. Self-priming pumps can lift the water from a lower level and prime automatically.

Prepare materials. You will need the following: PVC pipe, PVC pipe fittings, PVC cement, and hack saw.

Select a location. Preferably, the pool pump must be installed as close as possible to the filter and the pool. This is to ensure efficiency. If your pump is not self-priming, it must be installed level on the ground and below the pool water level.

Install a pipe to the pool’s skimmer device. This is an inlet pipe. Pools have a skimmer device, which acts like a strainer to prevent leaves or other debris from getting into the pump and filter. Install the pipe from the base of the skimmer to the inlet side of the pump.

Install another piece of pipe from the outlet side of the pump to the inlet side. This is an outlet pipe. Make sure that you measure the distance from the outlet pipe to the inlet pipe carefully before cutting and installing.

Apply cement. Apply PVC cement to permanently connect the pipes to the pump.

Connect the pump to a power source. Ensure that the electrical supply is compatible with the pump’s voltage, phase and cycle. Also, make sure that the wire size is adequate for the rating and distance of the pump to the outlet.

Prime the pump. (This is not needed for self-priming pumps) Note that during installation, you should block the water from the skimmer unit. Fill the skimmer unit with water. Never operate the pump without water. Water works as coolant and lubricant for the shaft seal. Open all suction and discharge lines, valves and air bleed on the filter (some filters may not have the air bleed).

Test the pool pump
. Once the applied PVC cement has dried up, it is time to test the pump. Plug in the pump to the power source. It should take only a few seconds for the pump to start forcing water into the pool. Test for leaks also. The pipes you connected should remain dry.

These are the simple steps to follow to connect a pump to your pool. Please note however, that a clean swimming pool is a combination of proper filtration and water chemistry.
