You went to all the trouble to swap the inside of the pump? You could
have just put a VERY healthy squirt of the grease into it and pumped a
couple of times to spread it all over the in side of the cylinder?
Swabbing leaves a very thin coating...whereas a good squirt of it gets
onto everything in pump...any excess will flush out without any harm to
anything.


Two questions result from that and the above.

First, is that sufficient, or do I need to take the piston out and put
it on the O-ring?

You used so little that you'll prob'ly have to do it again in a few
months, so don't worry about it till then.


Second, the pool stuff is markedly thicker than that provided in the
rebuild kits.

The thicker the better...it doesn't wash out as fast.

Because it makes little sense without it, I apologize for leaving in
the entirety of the conversation until my followup:

I've got terminal density, I think, as I recall your recommendation to
this effect (long) before. However, on followup then, it was my
recollection that the PHIIs don't let you do that.

So, assuming I misremember (happens more and more lately), where,
exactly, do I put this heavy squirt? As I (think I) understand how
this thing works, if I were to take it off the base as I did, and
merely put a large dollop of the grease in it, reassemble, and pump
away, it would immediately go out the joker, other than that which
managed to scrape against the sides.

Or, is there somewhere else I put it? As I did it, I put a pretty good
layer around the cylinder. My first attempt (years ago, now) had me
putting it down the flush/dry valve, and the output to the bowl,
because I couldn't see anywhere else (which was supposed to be so easy)
which, of course, thoroughly lubed the ball and seat and made the seal
not very good there.

So, apparently, I have no picture at all of how to put in the grease of
which I now have a very sizeable (well, at least as compared to the
stuff wihch comes with the rebuild kits) tube.

Pardon my density on this matter. I'm pretty sure I could field
assemble, in the dark, blindfolded, one of these units, so I think I
know where stuff is. How do I lube this better than I did? Take off
the base, put a tablespoon of grease on the bottom of the piston? Or
on the flapper weight? and expect it will make its way to the O-ring
and walls? Or through one of the two ball valve locations? If
swabbing the cylinder is trouble, I can't imagine I'm supposed to
disassemble the piston/cylinder, which would be necessary to grease it
through the top of the piston, the only other possiblility short of
removing the air valve of which I'm aware.

And, of course, if there's a simpler way, while I don't mind (I've got
long fingers) doing it, if I don't have to swab/slather the cylinder,
I'm all for it :{))

Thanks, as usual, from your densest student...

I've rebuilt my PHII's several times, and you really have to
disassemble it to lube the piston properly. It sure would be nice if I
could figure out how to do it without disassembling though... I
basically let it go a couple of years then rebuild it, lubing it at
that time. In the interim, I lube the shaft and the wet/dry rotor
several times.

I say try a poop sized dollop in the bottom pipe as far as you dare
push it, plugging it up, then flush slowly with a minimum of water.
Chances are two of three times that it will get pumped and slathered
through all the areas that need it. Would hot water help, d'ya think?
Might work out better than dissassembly again. That stuff floats,
right? Does that mean we can hope to sequester a dollop in the top part
of the pump, to bounce around for a while, doing it's work?

Now, about the environmental aspect of flushing all those hydro flouro
carbon artificial teflon greases...

How about bacon fat, or even vaseline?

Here's what Raritan says:

"Remove the pump from the base, pull the piston all the way up, then
smear the grease all around the pump cylinder, beneath the piston.
Sure, some it it will be forced out through the joker valve, but
there's no other way to lubricate it. No, you don't have to ids-
assemble the pump (although, to some people, just removing the pump
from the base might be considering disassembling the head. )"
