Choosing the right pump is a very important decision for your swimming pool. The pump works with the rest of the equipment to keep your swimming pool running well. A good quality pump that is the right size for the pool will help the rest of the equipment to work optimally. Be sure you choose a pump with the appropriate hp for the size of your swimming pool—too small and it won’t work effectively, but too big and it will simply become less cost-effective and energy-efficient.
