Jabsco 18910-4007 Upper Housing Kit
The Jabsco 18910-4007 is a genuine Jabsco upper housing kit for a Jabsco diaphragm water pump. The upper housing carries the ports and valve chambers. Jabsco uses this part number on specific models only, so match it against the parts list for the model number on your pump plate before ordering.
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.
