Skimmer baskets are designed to collect debris and leaves from the pool, and filter them out to stop them going through to the pump. Too much debris in the skimmer basket creates water restriction to the pump and eventually this can split the skimmer basket. The problem with this, is that once the skimmer basket is split, it allows for the debris to flow through to the pump. This can cause Impeller blockages and pump damage. Solution is : Always try to keep you skimmer basket as empty as possible. Just because you are not swimming in your pool, doesn't mean that you don't need pool care. A pool cleaning and maintenance schedule should still be followed to keep your pool functioning correctly and to look after your pool equipment
