Jabsco 18920-9043 Diaphragm Pump Service Kit
The Jabsco 18920-9043 is a genuine Jabsco service kit for Jabsco diaphragm water pumps, containing the valve kit, diaphragm kit, lower housing kit and slide clips needed for a complete wet end rebuild. It is listed for Jabsco 31600, 31605, 31620 and 31670 series diaphragm pumps.
Diaphragm water pumps rely on the valves, diaphragm and housings sealing well to build and hold pressure. Worn valves or a torn diaphragm show up as a pump that cycles, will not hold pressure, loses flow or will not prime. Replace worn parts as a set where possible, keep the pump clean inside, and protect it from freezing.

Frequently Asked Questions
Q: Why does my pump cycle when no tap is open?
Leaking valves, a system leak or a worn pressure switch are the usual causes.
Q: How do I protect the pump over winter?
Drain the pump and the system, or use a potable antifreeze made for water systems.
Q: Should I fit a strainer?
Yes, a strainer on the suction side keeps debris out of the valves.
Q: Can I rebuild the pump myself?
Yes, with basic tools. Note the orientation of each part as you remove it.
