Hello all, I've got what looks to be a leak in the main of our new home (2nd week in, so far). The inspector must have overlooked it, since the home wasn't in use and no significant amounts of water had been run. In the sizeable crawl-space of our home, there is an area that was dug out, where our main enters the ground. I noticed this ditch before completing the purchase and observed that it was dry. I immediately guessed that there must have been some plumbing emergency that necessitated digging around the main. I assumed it was done awhile back and moved on... Then, one day, I happened to be in the crawl-space after my wife ran the washing machine and noticed that soapy water had pooled in the ditch. I never waited/checked to see the water drain fully, but suspect there's a hole in the main somewhere below the ditch. The water bubbled some when my wife used the kitchen faucet. As well, there appears to be bits of toilet paper now - but no smell of sewage, yet. I'm convinced that we've inherited a big problem, and am more concerned that it isn't helping our home's foundation. My only hope is that the previous owners left things in a manageable state, since they apparently lived with it for however long. Tangentially, as the new homeowners, we're required to update our sewer lateral in 6 months. Any chance that work would address this issue? Or is this more likely to complicate things? Now, I can install a toilet or sink, but this is completely beyond me. (It's our first home.) I'd really like to know what steps to take next. Any advice is truly welcome. Plus, when plumbers charge $185/hr, it's cost less for them to fix the problem, rather than paying them to first diagnose it. Many, many thanks in advance!!
