Cleaning Out the Crawlspace and Re-Plumbing

19 photos · plumbing

The crawlspace was a dirt floor with decades of debris, exposed plumbing, and an oil tank that needed pumping. I had the tank cleaned out, dragged out the trash, then poured a thin concrete rat slab so I had a real surface to work on. While the joists were exposed I rebuilt the plumbing — new copper main, PEX trunk lines, PVC drains routed clean — so I'd never have to crawl down there again to chase a leak.

  1. What I started with — dirt floor, joists hanging full of old plumbing and posts shimmed up on whatever was handy. Before
