Compatibility / Fitment Guide
Direct fit: Jabsco 29090 and 29120 manual marine toilets, including compatible -3000 Twist ’n’ Lock versions, where the parts diagram specifies 29092-1000. Jabsco also documents this valve in selected 29200 electric-conversion and 58xxx/58500 toilet systems; verify the exact parts diagram before ordering.
Installation: the valve is sandwiched between the pump outlet and discharge elbow; the triangular/flanged side is oriented into the elbow per Jabsco service guidance. Isolate seacocks, wear protective gloves and catch residual waste before opening the joint.
Not universal: do not select it solely from a 38 mm discharge-hose size. Other Jabsco electric models and other manufacturers may use different joker valves.
