What Does a Pump Do?
The pump is essentially the heart of the swimming pool's circulation system. Your pool's circulation system comprises the elements of your pool that take water from the pool, filters it, sanitizes it, and returns the water back to the pool. If your pump is not running, the water from your pool is not being properly circulated or filtered.
The Importance and Function of the Filter
The filter and pump are the heart and lungs of the pool circulation and filtration system. The primary purpose of the filter is to keep your pool clean by removing undissolved debris from the pool water. Pool filter options include: cartridge, sand and diatomaceous earth (D.E.).
