Common Concerns Answered
Is the 500 GPH flow rate sufficient for all situations?
The 500 GPH rating is optimal for most routine bilge water removal and for addressing common water ingress scenarios on smaller to mid-sized vessels. For exceptionally large vessels or immediate, extreme flooding conditions, a higher GPH rated pump may be considered, but this unit excels in reliability and airlock prevention for its intended applications.
What does 'not external ignition protected' mean and why is it important?
This designation means the pump is not designed for installation in an area where flammable vapors are present or likely to accumulate, such as an engine room. In such intrinsically safe environments, an ignition-protected bilge pump is mandatory to prevent sparks from igniting fuel fumes, a critical safety consideration for engine compartments.
Why choose a manual pump over an automatic electric one?
Manual pumps offer direct control and can be a reliable backup when electrical systems fail or during critical dewatering. The Attwood Tsunami MK2's manual operation, combined with its patented airlock elimination, provides dependable performance precisely when you need it, without reliance on a float switch or automatic circuitry.
