Working on a project to expand grey water capacity...need to install a 3/4 pipe thread fitting on the bottom of a blue boy. Obviously I want it to be leak proof.
If I could reach my hand inside the tabk, I could back up the drain fitting with a jamb nut and gasket...but I cannot fiy my hand inside the dump hole on top of the tank.
Anyone have any ideas?
I guess I could just epoxy around the drain fitting on the bottom?

Tx, Bill

Use dump cap with hose fitting?
Find someone with smaller hands?
Not sure quite sure what your trying to do, this will be for fill?. our tank has a hose fitting opposite end of dump cap. 15gal tank. I dont think Id relie on hose thread in the thin poly tank without back up. Wonder if theres possibly some type of a flanged fitting.

I need a way to drain the tank from the bottom.
They are all designed with a dump cap and 3/4" vent hole on top...the only way to dump is to tilt the entire tank.
I want to mount the tank on my hitch haul for extra capacity when on extended road trips. Then when I get to a dump station, I just screw a length of garden hose on and let it drain.

If you put the drain fitting directly below the 4" inlet you could use a large socket with extention on the jamb nut .

Yup beat me to it, in looking some of the fittings, small go thru and seal from inside nut on outside. If were directly below dump cap could be done with socket. I was thing of flanges do do same thing for more surface.

You might try something like this on the bottom of a plastic bucket as a test.

Cut a round hole 2 inches in diameter in the center of the bottom of the bucket.

Build a 4-6 inch round metal plate out of 1/8" aluminum and in the center of the aluminum plate, install the 3/4" drain fitting you are hoping to use.

Drill holes around the perimeter of the aluminum plate for self-tapping-screws and mount the plate/fitting to the bottom of the bucket using either sealant or a rubber gasket.

If the experiment with the metal plate holds up without leaks, it might be a remedy to your problem with the blueboy.

Bobndot is on the right track, except instead of jury rigging a makeshift fitting, you would do better to buy a proper "bulkhead" fitting from a plumbing supply house. They are common, come in many different materials, and are easy to install. In your case you would have to fish the internal fitting with gasket through the top hole with a bit of wire. Once pulled through the hole it can be tightened to a good seal quite easily. That way the gasket is on the inside and easier to seal. Here is an example....http://www.plastictanks.ca/category.php?cat_id=038
