Whale Strum Box – Bilge Pump Strainer with Non‑Return Valve
Prevent blockages and back‑flow in your bilge pump system with the Whale Strum Box, designed for use with either manual or electric pumps. Choose from top‑entry (for deeper bilges) or side‑entry (for shallow installations). Made from durable plastic (polypropylene), it fits 25 mm or 38 mm (1″ / 1½″) hoses, includes a removable strainer screen, and features an internal non‑return valve to prevent drain‑back—allowing near-complete bilge evacuation 

This essential accessory mounts at the lowest point of the bilge, enabling maximum water removal and protecting pumps from debris, while keeping the intake primed after pumping .
