We're installing a composting head in our boat. I'd like to use the existing pumpout hole for the vent. The hole is 2-1/8" in diameter.
Anybody have an idea of a vent (preferably solar) that I could use that would fit in that hole?
Thanks,
Joe
Air Head actually recommends nothing smaller than 2 3/8" opening. That's the diameter of the fan blade swing. I know it doesn't seem like much, but it really cuts down on air flow and may affect how well the toilet works. Just FYI.
