Has anybody got an opinion on the new SaniPottie 970 series Portable Toilets? Are they as durable as the older 960? Or why the change? Thanks -Tim

SaniPottie
I bought one in January 2008 (the 5 gallon holding model). I had a few questions about the product and Dometic answered them right away. I am in the process of installing. The product comes with everything you need. I purchased the item as an MSD. I am now connecting everything to the existing vent and pump-out. I am very pleased with the support, product, price, and array of installation hardware that come with the MSD 975. After all tyhe horror stories about marine toilets this item seems to be a perfect replacement for the Raritan PHII that came with the boat.

As near as I can tell from the info on the SeaLand site
The only difference between the 960 series and the "new" 970 series is the addition of a tank level indicator.

My major concerns where they switched from polyethylene construction to ABS plastic, and like anything new that deals with sewage you tend to be cautious. The idea is to replace the compact head and 6 gallon tank with the larger MSD version tied into a pump for overboard discharge.

I missed that litte detail...
But no reason to be concerned about ABS. It won't permeate and is "stiffer"...which means the walls don't have to be as thick to support the weight of the user or the tank contents. And, glues, sealers etc will bond to ABS, whereas, nothing bonds to PE. Whether to replace the PH II with a self contained system is your choice--and an excellent choice for smaller boats (up to about 27') But you need to know that 90% of the "horror stories" are from those with cheaper toilets and are often the result of neglect and/or improper use. The PH II has been rated the best manual toilet

I just purchased the same model but need help
Peggy, Thank you for all of the helpful information you provide all of us. I just purchased the SaniPottie/Dometic 970 also. I have a height issue and bought the 2.6 gallon model. My questions are: If I install a small holding tank located below and to the side of the porta-potti, how does the waste get to the holding tank? Do I need a manual pump or macerator? Also, can the vent line go vertically on a slight angle to follow the contour of the hull? Does it have to be 18" before the 180 degree turn or can it be a little less? Thank you again.

Why put the tank right next to the portapotty?
It needs to be far enough away to provide enough room for the hose from the portapotty to it, with a pump (yes, you need one) in the line to transfer the waste from the portpotty tank to the extra tank. Don't forget, you'll also have to install a new vent line for the extra tank too. If space is an issue, your best option is most likely an extra tank for the portapotty...when the first one is full, swap 'em out. You can store the full one in the same space you were gonna put the tank. Re the portapotty vent line... 180 degree turn?? Noooooooo...that'll prevent ANY air flow through it needed to keep the tank aerobic. The vent line needs to be as short and straight as possible, on an MSD portapotty, same as any other waste tank ...which, if you need a 180 in it to get to an existing vent thru-hull, means installing a new vent thru-hull.

Great news
Peggy, The holding tank will be approx. 18"-24" away. So a hand pump or macerator will do the job. Space is only limited in height (13"). I am aware the holding tank needs a vent line also. For some reason I thought the vent line needed a 180 loop in it. OK. The vent line goes straight up from the portapotty and to a thru-hull (above the waterline - as high as possible). Can the vent lines travel horizontally for a small distance?

Vent lines should be entirely horizontal...
Or as close to horizontal as possible. But that's not always possible on a sailboat, so they need to be as short and straight as possible...which means a diagonal route may be the best option for you. I still think that a spare potty tank is much better option than plumbing in a holding tank and a pump.
