[Shop-talk] adding RV dump connection to septic

[Mark Andy]

Howdy,

I've got a fairly typical rural septic tank (two, actually) with leech 
field setup.  I've also got an RV.

I want to put in a T or whatever in the line from the house going to the 
septic tank, with a screw on cap so that I can dump the RV's tanks at 
home.

Is there anything to this beyond just digging down to the pipe, gluing in 
a T with a capped riser, and filling the hole back in?  You do glue septic 
pipe, right?

Do I need to worry about freezing weather with this?  The existing pipe is 
(presumably) below the frost line, but now I'm going to have a 2' or 3' or 
whatever pipe with essentially no insulation going up above the frost 
line...

Thanks for any advice!

Mark
