Product Questions & Answers (4)

Question by: Lyle M on Aug 10, 2025, 6:00 AM

what's this strainer used for exactly, is it for pump intake or something else?

Answer by: Customer Support on Aug 11, 2025, 1:28 PM

Water pump intake protection is the main job here. The RH 40B round hole strainer sits at the inlet side to keep debris from getting pulled into the pump. It's a 4-inch unit made by Kuriyama under the Seal Fast line, and it falls into the same product family as foot valves and skimmers, so yes, pump suction applications are exactly what it's built around.
