I've been getting mixed info about pumping out. Should the head be in pumping mode or closed. Mine is a manual Jacob.

You've just provided all of us with a good indication of your approach to everything on your boat that requires even a little maintenance.I used to unlock the twist and lock so that if the pump sucks really well and the vent has trouble keeping up, the head would hiss. Why? 'cause as Peggie says, if you've got a plugged vent it's a problem. My boat has the craptastic vent-in-the stantion thing. So it's essentially a 3/8 inch hole.
Why used to? 1. The pump out at my marina doesn't suck all that much so it's not really a problem.
2. I mainly empty with a macerator once out past 3 miles.
Peggy, I'm pretty sure Paul's tank is black. Like ours, it's got what looks like white paint overspray on it. Ours (hull #31) also has the elbow fitting, but installing a larger vent like Paul did is on my to-do list. Luckily our head usage is fairly light, with a fresh water flush, and has only been #1, so a small vent hasn't been an issue, yet!Nice job, Paul. Why did whoever installed the original vent line use a 90 degree fitting on a line that they had to know would run straight up??? Although boat builders are the worst sanitation system plumbers on the planet, I don't think yours was a factory installation...'cuz your tank is white. Catalina has used black Ronco waste tanks (haven't noticed what color the water tanks are) for decades.
