See my sig for equipment. The filter is a Sta-Rite System 3.
I cleaned my cartridges 2 weeks ago, and thought all was fine, but I just noticed that at high RPM, I get about 3 drips.
When my system turns on, for some reason my variable speed pump always senses that it needs to prime itself (it doesn't really need priming, I'm sure I have no suction side leaks), and runs at full RPM (~3000 something) for a few seconds before dropping to its normal speed. This is when I get about 3 drips from the filter, where the upper and lower parts of the tank meet (where the big o-ring is).
1. Ignore it.
2. Take the filter apart, clean and lube the o-ring, and re-assemble.
3. Get a new o-ring.
4. Try to reset my pump sensitivity so it doesn't needlessly try to prime itself every time it comes on (I've never messed with this, I left it in the factory default setting).
The filter is 3 years old. I have cleaned the cartridges 6 times -- the pressure never goes up (yet) so I just do it in spring and fall.
The manual says not to lube the o-ring, but based on comments from TFP veterans, I lubed it (sparingly) the first time with a silicone lube of course.
When priming at high RPM, the pressure reads 15 PSI; when running normally at 1400 RPM, the pressure is close to zero, but maybe it's 1 or 2, hard to tell.
Thanks for any suggestions!
