Pipe got ripped off our waste tank and was wondering how the toilet is connected to the tank? Looking at it from underneath it looks like the tank is just held up by the cross support brackets.
there is a little more to it-you must get a tank perferally like the one you are replacing-all holes must be put in new tank at proper locations-discharge hole must be plumbed-vent pipe must be reinstalled or replaced-removing toilet is the easy part it is only bolted to floor w/a seal ring between it and tank input pipe--good luck-it cost about1500.00 to have it done.
If you are not moving the trailer such as seasonally parked in a campground you can basically attach a drain pipe directly to the grey water pipe and go directly into the ground.
