Jabsco 18912-3040 Diaphragm Repair Kit, TPE
The Jabsco 18912-3040 is a genuine Jabsco diaphragm repair kit with a thermoplastic elastomer diaphragm, for Par-Max 4 diaphragm water pumps. It is listed for Jabsco Par-Max 4 diaphragm pumps, including the 31620, 31670, 31800 and 31801 series.
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.
