Had we just poured the dye packet down the drain, we would have thought all was good.

@Luke Badalaty, only if the existing sprinkler heads are the flexible ones ( like below ). most sprinkler heads are hard piped, which means you would have to shut down the system, drain it, open up the ceiling to extend the pipe and then close it all up.

While living there, I've learned a few small tips about the house such as how to deal with the mice (we're in the city) and how to clear the back patio drain when it clogs (it looks bad but it's really not).

Possible new drain tile?

The sewer drain pipe from the washer runs outside the home, and connects around to another point under the house, due to the lack of crawl space.  

MileIQ is good as well but can drain battery. 

Too much of a time drain on my life with the drama and they are low producers compared to what I can close on my own spending time directly with clients.

Fix the pipe at the same time included with the repair would be 3 new drains int he garage for a future kitchen sink, bathroom sink and shower drain.

I mean what are you going to do run water and plumb a toilet and tie into the existing sewer/drain field?

I see it as an investment in my future and not $ down the drain like the rent was.
