Jabsco Twist 'n' Lock Manual Marine Toilet

Product overview

Jabsco Twist 'n' Lock manual marine toilet: a white ceramic bowl with a self-priming, double-acting hand piston pump and a separate flush-control lever. It flushes with sea, river or lake water and discharges overboard where regulations allow, or into a holding tank. A 90° turn of the pump handle locks the waste valve shut against siphonic flooding and backflow.
