The SB4222 is a strainer with non-return from Attwood/Whale. See below for additional product information.

The Attwood/Whale SB4222 strainer fitted with valves is indispensible for manual bilge pumps, where the valve prevents drainback and loss of prime in-between strokes. The greater the lift, the most important a foot valve becomes.
