[Shop-talk] adding RV dump connection to septic

[BSHolden at aol.com]

Mark;
 
1) My cleanout from the barn toilet consists of a tee in the mainline that  
is right at ground level, in fact I would not hesitate to use that fitting for  
dumping the RV waste tanks (and had to do so via a hand carried 5 gallon 
bucket  14 years ago when living on-site in a camping trailer while the new house 
was  being completed).
 
My septic installer explained to me that the heat generated by the bacteria  
from the septic system would keep the pipes warm enough to prevent freezing. 
14  years on and I have not had a problem with that install.
 
2) At about the same time while I was drilling fence post holes just  4' deep 
I hit the septic main line from the house. Repaired with the rubber  couplers 
and a short length of the 4" PVC line. The rubber couplers allowed  enough 
wriggle room to achieve the repair.
Just eat your Wheaties that morning because wrestling those couplers takes  
some strength. Oh, and cut off the water supply to the house as wives and  
other occupants have an ingrained habit to flush the toilet while you're in the  
middle of your project.

Sorry,  replace "gluing" there with "rubber (femco?) couplings"... I can't 
imaging  I'll easily be able to get the pipe to move enough to work a glued 
in T  into place.
