How do I add a 2-in abs threaded connector to a black tank.

[Kenster]

Has anyone added a clean-out port to their black tank? I want to add a 2 inch threaded ABS connector to my black tank. Any suggestions on epoxies or other adhesive sealants? Am I correct in assuming the black tank is made from abs plastic?

I replaced my black water tank using these fittings.

I had to buy entire kit but cost is not bad.

If you can, swing up the side panel and see if there is plenty of room above your black tank ( as there is on my 05 diplomat ). I cut a 8 in square hole and used the piece of plywood as a plug and screws with wing nuts. It is easy to take a hose and flush out the tank. end of any problems.

I'm assuming you insert the screws from the inside pointed out, and apply a little silicone between the tank and the wood?
