Job Shack Portable 300 Gallon Waste Tank

[ILOVEFISHINGEDISTO]

We're living on our property with our 2017 Keystone Montana Legacy 3920FB. Preparing to move into it full time in December. I'm needing information on how to plumb the Job Shack 300 gallon waste tank. I've purchased the fitting coming off the camper waste out gate. I'm needing to know how or what to use for fittings from the pvc piping into the tank. Any thoughts would be helpful. I've seen where you can use a rubberized connecting hose instead of permantely gluing the pvc together so you can take a part and reuse. Our plan is to move it in 2 years to a beach island in the south. email me with direct help. Thank you.

I think you are referring to a "No Hub" flexible coupler for your piping. They come in various diameters to fit what ever you are trying to join. No gluing and you can disconnect and reconnect easily.

Here is a sample of No Hub couplers from Amazon to give you an idea.

I am not sure what built-in fittings/nipples those tanks come with.
The tank in the screen shot below has 3" "ports" (or nipples I think) to allow you to slip rubber couplings like Carl showed over them and connect PVC pipe. You will need something like the first screen shot below hooked to your RV sewer outlet to connect the PVC pipe to the RV.

If you will be pulling the RV from time to time - the setup in the 2nd and 3rd screen shots might be better. You could un-hook from the tank and hit the road.

My question for either set-up is about the access hatch/port for the septic pump guy to come suck out the tank is located. Also - what size does it need to be to fit the sucker hose?

Is that tank going to need a vent pipe/valve for air to get out as you are dumping your RV tanks into it?
Maybe for pumping out you could use the inlet from the RV side?
You would need to check with the pump out company what kind of connections are best and that they have.
Maybe a tilt platform to tilt it up when they are pumping it out?

What Mikendebbie said. Only difference for me is I use 3" ABS to run from tank to rig. I then use short 2' sewer hose to connect from rig to ABS.
