Well, we've owned this place for 4 years now and the gremlins are starting to surface. Last fall, I noticed the garden behind the house would get wet whenever we took showers or ran the washer, etc. It got worse over the winter with a standing flood every time we ran more than a bit of water. I finally get Around to digging up the line and here's what I find. The line is crushed all the way back underneath my deck and I have good reason to suspect it is compromised further down towards the drywall as well! I really hate to do it, but I guess my best option is to divert to septic since if the addition the wife wants ever happens, I will be forced to do so anyways. Anybody know what went wrong here?
