For a pump which is already in service (and was rebuilt with nearly all
of the supplied grease going onto the piston O-ring), this is how I
regreased it:

I took off the base, put the piston at the highest point, and then
thoroughly swabbed the entire cylinder (since it was difficult to
control, I did the part under the stroke a bit, too) with the
non-petroleum swimming pool supplier Teflon grease you'd previously
recommended.

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.
