adding a waste tank port...

[floorguy]

now i know they have the 2.5" elbows you can mount on....

but i am thinking i want a 3"pvc type.....that way i can run pvc out to my hook up....

PLUS there are a helluva lot more 3" parts then 2.5, for almost anything....

which makes it easier to make a split if i need to for dual wanding, yet gives it plenty of flow through...

so i was wondering about putting it on top... ill take a pick to show what i am talking about

3" ABS is easy to work with, cheap, and very sturdy. 3" hose fits perfectly into the ABS couplers. I used it to plumb my old big red system and I have it plumbed under the truck for the CanAm. I made an adapter with a 2.5" coolcuff to attach it to 2.5" hose that I run from the truck.
You can use a toilet elbow to mount to the top of the tank. It has a 90degree bend plus screw holes for mounting. Just silicon it to the tank.
