Bill, Ben & the Group,
I didn’t replace the joker/check valve this time because it wasn’t leaking. And (maybe someone can chime in on this..), because in order to replace the joker valve you have to remove the output nipple. But to do that, the only way I have succeeded so far is to use a heat gun to make the output hose flexible enough to bend so as to be able to pull it off of the output nipple. I’m afraid that repeatedly heating the hose every year or so, so as to be able to replace the joker valve and maybe the output nipple, will cause it to fail. I’ve replaced the aft output hose but would like to put off doing a similar job again if at all possible.
For spares I keep at least 1: 24V motor, white round plastic seal housing that screws to the motor, blade & nut kit, output nipples, Jabsco re-build kits, and now a bunch of 1.5MM X 75MM O-rings.
Also as an aside, I’ve replaced some of the four slotted screws that attach the seal housing to the toilet base with hex-drive screws. This solves the problem of the screwdriver constantly slipping out of the screw head as you’re hugging the toilet and watching the flashlight roll away while trying to disassemble or reassemble the unit. I’m not aboard right now so don’t have the size available.
