Jabsco Service Kit for 31600 31620 31630 Pumps

The Jabsco 18920-9043 Service Kit rebuilds the internal wear parts on the 31600, 31620, 31630, and 42755 Series pumps. These are the components that fail first even when the pump body itself is still in good shape.

It contains the diaphragms, valves, and clips needed for a complete rebuild. That's a genuine full service rather than just one replacement part that leaves other worn components in place.

Rebuilding with a service kit is typically far cheaper than replacing the whole pump. It's worth doing preventatively on a schedule rather than waiting for a failure that leaves the head or toilet system out of commission. See what else we carry in bilge and water pumps.
