Any suggestions for lubricating O-Rings that are used for water pumps,
basically I want to extend useful life as much as possible. Someone
suggested lithium grease?

Petroleum Jelly (Vaseline)

I don't think so---will eventually ruin the O ring

I do. Petroleum and Butyl rubber are completely compatible.
Use of Vaseline on Buna-n O-rings is a standard procedure.

the manual for my pool pump said to use silicone grease. i know rtfm is
against the guy rules though....


Definitely RTM wasn't part of my Male Manual LOL..
