Lubricating a PH II is very easy
However, you shouldn't need to do it for at least a year. To lubricate a PH II: Remove the air valve (part 1203W on the drawing). It's a little square flat nut that has a hole in it on the front of the pump housing that looks like it's molded into the housing, but actually unscrews. Stick the tube nozzle in the hole, give it healthy squirt, pump the head a few times to spread it all over the inside of the pump cylinder...clean the air valve and put it back. (If it leaks, wrap a little teflon tape around the threads). You're done for a year (maybe only 6 months if you use your boat year round). To lubricate a Jabsco manual: remove the two screws that hold the top of the pump on...lift off the top, pull up on the pump handle to raise the seals and o-rings...squirt SuperLube. Pump a few times...replace the cover. SuperLube is high quality teflon grease...and teflon grease is what's in all toilets when they leave the factory. It won't damage rubber, and won't just wash out in a few flushes the way anything poured down the toilet does...it lasts at least a full season...sometimes as long as two years, depending on how much the toilet is used. The best time to lube a toilet is in the fall, as part of winterizing, because it protects the rubber parts in the toilet from drying out. Follow the above directions for your toilet after you've pumped antifreeze through the system. Come spring, you won't have to lube again...you're good to go for the season. Btw...it's not the pump piston that needs lubrication, it's the pump cylinder wall. The piston never comes with it, only the rubber seals and o-rings around the piston do. Proper lubrication annually as PREVENTIVE maintenance--instead of waiting until the pump needs it--reduces seal and o-ring wear, protects the inside of the pump cylinder from scratches and scoring, and greatly extends the time between rebuilds. If you keep your new PH II properly lubed, it shouldn't need a rebuild kit for 5 years.
