Home inspections turn up plumbing problems all the time. Most of them get flagged, noted in a report, and then either ignored or patched over just enough to get through closing. This one wasn't going to fly that way. The drain line under this East Tacoma crawl space had a hidden leak, severe corrosion eating through the pipe wall, and a slope problem that let waste and water sit in the line instead of draining out. That combination - left alone - causes real structural damage over time.

Here's what we were working with when we pulled the failed section out. The old galvanized pipe had corroded through completely, and the interior of the existing ABS sections was packed with buildup that had been accumulating for years. That kind of restriction doesn't just slow things down - it backs up waste, holds moisture, and puts constant stress on every joint in the line. It wasn't a matter of if it would get worse. It already had.

We replaced the damaged section with new ABS piping, code-compliant fittings, and proper supports to hold everything at the right slope going forward. No flex couplings hiding a bigger problem. No wrap-and-pray patch jobs. The new line was tied in clean, secured to the framing, and fitted with fittings that are actually rated for drain-waste-vent use. That matters more than most people realize - not everything that fits will hold up under daily use.

Crawl space drain work is tight, dirty, and easy to do halfway. A lot of contractors will do the minimum to get the job signed off. What we're focused on is making sure the repair holds for the long run - proper slope, correct materials, and connections that don't leave question marks down the road. That's the difference between a real fix and buying yourself another problem in a few years.

If a home inspection flagged plumbing issues on a property you're buying or already own, that report is telling you something worth listening to. Corrosion and poor slope don't fix themselves. We do sewer repair and replacement work throughout the Tacoma area and we're straightforward about what actually needs to be done versus what can wait.
