Haven't checked Sailnet's threads in at least three years. According to the 2I8 posts, I've been missing some good advice. Good to see that you're still out here providing good DIY wisdom Paul!
I'm looking at replacing the old 'Firestone' bag this summer, and re-designing the septic system to pump overboard. The existing setup has several plastic gate valves installed between the thru-hull (beneath the bag), the bag and the toilet. I'd like to keep the existing head (Jabsco, replaced in '03), install a whale gusher pump with lockable y-valve, and new solid holding tank.
Can you provide me with more information on the solid tank you were able to buy? Thanks much. ~Joel
