The pump is essentially the heart of the swimming pool's circulation system.
The entire operation of the swimming pool is dictated by the operation of the pump. The cleaning system cannot, in general, operate without the main pump, and the pool water cannot be filtered without the main pump operating. It must be running at peak efficiency at all times.
Having a pump installed on your pool will cut down on plenty of your maintenance time. The heater will work more efficiently, the water does not sit for long periods, and the need for adding additional chemicals is lower than without a pump because they get mixed around with the movement of the water. The pump is also responsible for keeping your pool sanitized. You need to the correct size of pump for your pool.
You will notice a huge difference when your pool has a good working pump. There is less labor intensive maintenance for you, and your pool will keep you safely cool all summer long!
