Extra Holding Tank

[Carver Power]

Anybody ever added a extra holding tank, I mean by adding one hooked up to the one already on the boat ? I'm trying to stop using the weekly pumpout >
Thanks
I have a 30 gal. now, have room for at least a 30 gal new

Might be worh investigating the treatment systems (names like Purasan, Lectrasan, etc.), if you're not in a No Discharge Zone (NDZ)?

We have a 225 gallon tank directly under the head, pump out every three months or so out at sea. No Y valve, no smelly hoses, no hassle. I know you're about to tell me there is no room on your three stateroom four head sailboat for a tank that size, but we all know it's your choice.

There's always a way to increase the size of a tank. Having multiple tanks necessitates multiplying the plumbing, vents, etc... Which adds unnecessarily to the inevitable problems.
