Permanent Sewer hookup

[Bearhunter]

I am having a septic tank and concrete pad put on my farm. I have 5 wheel that I am putting on it. What is the best way to hook up 5th wheel to septic tank.

Welcome to iRV2.
A little more info is needed, is this a permanent set up, long, stay or mobil.

RV holding tanks and systems are not designed to be open all the time.
Best to fill to ~2/3 and then dump to get the whoosh effect for the best empty. Use lots of water in the black tank.

If a short time just use the flexible "stinky slinky"
If long term you could plumb with PVC or ASB, but don't leave the black tank valve open. Not a good idea to even leave the gray valve open.

Do not put any of the normal RV chemicals in the black tank. These will kill off the bacteria needed in you septic system and you'll be pumping it out instead of the bacteria doing its job.

I used a normal twist connector to connect to the dump valve and connected that to 3” pvc pipe using a 3” flex connector to attach the two together and then continued pvc to connect to septi tank. All available at Lowe’s except for the valve connection.

This is a permanent location install. Will not be moved. This is for hunting and fishing about 6 months a year.

Use pvc pipe with rubber furco connectors to attach to rig. Leave gray tank open and black closed. When you need to dump black, close gray and let it build up, a shower or two, them dump black and rinse by opening gray. I did it this way for years.

only leave the gray open if you have a P-trap in the PVC line or you can get sewer flies in your RV.

You might find this link helpful, How to connect RV to RV Park Sewer. Make sure you have a p-trap at the sewer hookup either using pvc fitting or make one in the slinky hose.
