The pump strainer basket is located in front of the volute and must be kept clean of leaves and debris. If you see any debris through the special lid, clean the basket at once.
Stop the pump and make sure it’s cold, and the suction and discharge valves are open. Remove the clamp and lid to reach the basket. Pull it out, remove debris, and rinse out the basket.
Then put the basket back into the housing. Fill the pump basket and volute up to the inlet port with water. Remove all elements (O-ring, lid, and clamp) to their places in the proper order.
Please, before basket cleaning, consult with the user manual.
