Over the years, we've seen plenty of main line blockages, and there's a pattern in homes with crawl space access. When sewage backs up into the shower, it's often a clear signal that the main drain is completely blocked. This Loganville homeowner was dealing with exactly that situation, and they suspected a sewage ejection pump might be part of the system. Accessing the crawl space, we found the main line plumbing beneath the bathroom. Visible water staining on the concrete suggested this wasn't the first time drainage had been an issue. Using specialized drain cleaning equipment, we cleared the blockage from the main sewer line. That restored proper flow and stopped further backup into the fixtures above.
