Peggie Read (again) your "Flush with Success" article, as my Jabsco head pump is now feeling like it could use some lubrication. You recommend dismantling the pump & rebuilding with new seals etc. plus a liberal coating of teflon grease. You didn't say specifically where the grease should be applied. Does it go over everything? Just on the rubber "O" rings? On the pump handle shaft? etc. Thanks --Ron

Lubricating the toilet
Last thing before you put the top back on the pump, put a HEALTHY squirt of SuperLube in it...pump a couple of times to spread it all over the inside of the pump cylinder...put the top on. You're good to go for another year. If you do this once a year, whether you rebuild or not, the toilet will need no further lubrication...plus the seals and o-rings will last a LOT longer, greatly increasing the time between rebuilds. In the fall, as part of winterizing, is the best time to it because the grease protects the rubber parts in the toilet from drying out over the winter. I've never recommended spending the money to rebuild a manual Jabsco toilet--not when a rebuild kit is about $50 and the whole toilet is usually on sale somewhere for $99. Just keep it lubricated and you should get about 5 years out of it before something in it breaks. When that happens, replace it.

Lubricating a PH II Pump
On a PH II the pump bolts down at the bottom with a a seal nut around the pump shaft at the top. I the only way to superlube this pump is to take it off the space. The reason I ask is that the space between the shaft and the socket for the seal nut doesn't seem big enough for a squirt. Thanks Dave

Be careful taking a Jabsco apart.
Ron: Be very careful taking a Jabsco head apart. Removing the screws is no problem. You can grease the shaft, seals, orings etc. The problem comes if and when you put the thing back together. The screws can easily strip out and you are 'shit-out-of-luck'. Also be care with the diaphram in the top of the pump assembly. If you get something on it that reacts with the rubber it will not seal. To make my long storie short, I stripped out the holes on the pump assy. Checked the prices for a new pump housing. The pump housing is the same price as a new JUNK Jabsco.

PH II...remove the air valve
The air valve is little flat square doodad on the front the the pump that has a hole in it (and btw, it does need cleaning from time to time)...it may look like it's molded into the pump cylinder, but it actually threads into the pump. Very carefully, using needle nose pliars, unscrew it to open up the pump...there's your opening into the pump cylinder to squirt SuperLube into. Clean the air valve and put it back.

Manhandling most things can damage 'em
However, you do have a point...also about what should and should not be used in a marine toilet. Teflon grease, which is what SuperLube is, is safe to use. Btw...what you call a "diaphragm" is actually just a flapper valve.

Nope...it'll wash right out
In fact, so will anything but thick teflon grease. There are other thick greases, but anything but teflon grease can damage the pump. So you only want to use the SuperLube that comes in a tube, not the spray nor the liquid. Super-Lube isn't the only brand...but like most products, the quality of various brands is all over the wall. I recommend the SuperLube brand because it's the best quality, lasts the longest, and costs about the same as any other brand.

Thanks --
Peggie Your suggestion worked very well. Amounted to about a 5 min job & made a very noticable difference. The biggest effort was in locating the Super-Lube grease -- went to hardware & auto supply stores (nope -- had Super-Lube oil though), went to West Marine (not with greases/lubrication or with the head stuff). Finally asked a sales guy as I was about to leave & he directed me to the "waxes & cleaners" section (go figure!). --Ron
