Your pond pump is the heart of your pond system, not too mention a considerable investment that needs protection. Installing a pre-filter is a cost-effective way to protect your pumps, help pumps run more efficiently, and extend pump life.
Pre-filters prevent debris like leaves, stones, muck, and sticks from damaging your pond pump. A pump without a pre-filter can experience significant reduction in water flow as well as undue stress on the pump impeller.
Pre-filters also help ensure the safety of fish and other small pond inhabitants by preventing them from being drawn into the pump.
