I never liked emptying the porta pot tank. Nasty job!
Whereas pumping out a holding tank is hassle free.



The only difference between pumping out a permanently installed
"pumpable" portapotty and pumping out any other holding tank is the
location of the tank.



..and the size!
With a Porta Pottie.... auch as my VISA MSD, visits to the pump could
be frequent.


Because they use so little flush water--only 1-2 cupfuls, a 5-6 gal
portapottie holds 50-60 flushes.

Otoh, the average flush volume from a marine toilet is about .5 gal...so
you'd need a 25-30 gal tank to hold the same number of flushes.

Although 2-3 gal portapotties are also available as "pumpable" models, a
tank that small isn't really worth the effort or pumpout expense. Nor
would I recommend going with a portable 5-6 gal model...'cuz full, the
tank weighs about 50 lbs, which is a LOT to haul off the boat and carry
anywhere.

What is a "VISA MSD?"


An older MSD that came with my Sandpiper 565 sailboat.

In Ontario, & I believe Quebec, you must have a pumpout...even on small
MSDs. I understand it's illegal to have a normal camping style porta
pottie on your boat. I bought my 1986 boat in Quebec..so it came with
the device.
