The vent lines on both tanks are 1 1/2" 
All previous boats IO had were only 5/8".
Holy crap! (pun intended!). What's the vent fitting look like on the outside??

1 1/2" vent lines and thru hulls, yes they are big but do their job 120%
Great addition and well thought out IMHO .

Yes Bud is talking about the rigid stuff. If it doesn't bend, it won't permeate. If you had/have Vacuflush, you only need rigid from the pump and vacuum generator to the tank. If that's downhill, you don't even need rigid for that as waste won't sit in there continuously.
It's usually not practical because of the way the lines are run but in a non-Vacuflush installation, anywhere that waste will sit, which is all lines lower than the tank between it and the toilet, is best installed with rigid line so the sitting waste won't permeate through the lines over time.

How are you guys making the transitions to and from the 1 1/2" lines to the PVC?

Dometic has the fittings........I think I got a couple elbows from a pool place but the adaptors come in the little kits.....with some thought it will work just fine....like I said you can't run it everywhere but it does a nice clean job when you are done.

KM, there is one thing for sure......all this stuff is much cheaper where you are.....
To add, I also found a tool that makes the fitting of that real nice white waste hose real easy.......its an exhaust pipe expander....the small one...... warm up the hose put the expander in and expand to fit ,pull it out and hose slips over fitting with some soap like a dream, then shrinks right back to fit perfect.
If you are interested I will post a pic of the thing...
