Hands-free drainage – with built-in automatic switch

A built-in switch senses the water level and starts or stops the pump without an external float switch. Rated for 12V operation and a maximum flow of 750 GPH, the control simplifies wiring and reduces component count.

Automatic operation removes the need for manual monitoring, so showers drain reliably even when unattended. Ideal for single-hander boat owners and busy caravan users.

Hygienic cabin protection – thanks to built-in check valve

An integrated check valve prevents backflow by allowing water to exit while blocking reverse movement into the bathtub and cabin. The valve sits inline, removing the need for a separate backflow device.

Backflow prevention keeps the shower area cleaner and reduces odour risk, preserving onboard sanitation. Useful for weekend cruisers and longer passages alike.

Simple upkeep and safe starts – with transparent cover, mesh filter and ignition safety

A transparent snap-on cover with a gasket seal gives visible access to the removable mesh filter for quick cleaning. An ignition safety feature reduces concerns when initiating pump operation.

Visible access and a tool-free filter cut cleaning time and help avoid blockages. Safe starting behaviour reduces electrical worries during installation and use.
