Rodney,

 

Should you truly be making this RV permanently non-mobil, you should by-pass the holding tank and go straight to the pipe connections. If you leave the tank active, it will have a build up of sludge and eventually a stoppage. If you do leave the tank in-line, let it fill and then periodically empty it, so as to flush out the contents.

 

Hope this from a long time RV'er has helped

Is there a kit or a instruction book on How to permanantly connect RV black water to septic tank ?

I would consult with an RV repair store. RV's generally use standard black ABS piping in the drain lines. You would be splicing into the line that goes into the tank.   If you don't intend to use the RV as a mobile unit again, you might be better to remove the RV toilet and replace it with a standard residential toilet, flange and drain lines. Remember, there is no trap on an RV toilet other than the slide valve. With the slide valve open, you have exposure to sewer gases. A residential toilet has a built in trap.

Hi RodneyOwens,

Remove the plastic side cap off the rear bumper.

Inside the rear bumper on most RV, you'll find the hose that attaches to your exterior drain.

This hose connects directly to the septic tank on most trailer park sites.

If this is at your home, you'll need to install the line onto the septic tank "fill line."

This hose might also be attached to the clean out plug on the fill line, but prop up the hose to ensure consistent downhill flow with no sags.

Sags will allow waste to collect in the low spot.

NOTE:
You use the word "permanent."

Because this hose may freeze and burst, you'll need to flush the tank empty and disconnect the hose in cold weather.

RV dealers sell tank antifreeze ... use it every year when cold weather arrives.
