Job location: Greenville, TX

A residential kitchen sewer issue was resolved through excavation and pipe replacement. The technician discovered a completely disconnected sewer line saturating soil beneath the home. After installing new pipe with dual supports, a second excavation exposed an old cast iron line causing sewer gas escape. The line was capped and sealed to prevent further odors entering the home.

Key Facts

We were called out for an issue with the kitchen. After performing a smoke test, we found that smoke was escaping from below the floor. We dug a tunnel over to the kitchen stack from below the home, from the rear of the home. Upon completion of excavation, we found that the sewer pipe was completely disconnected. It was saturating the dirt, causing the dirt to smell extremely bad.

We started off by cutting out the entirety of the old section of pipe and installing a brand new section with dual supports to ensure that everything is properly anchored so this would not occur again in the future. After completion of that work, we performed a free smoke test on the property. During the smoke test, we found that the old cast iron line for the kitchen was still connected to the sewer system, causing the sewer smell to occur.

We had to tunnel another three feet to expose the cast iron that was not inside of a concrete beam. After exposing the cast iron, we cut and reconnected it with a cap to seal off the old sewer system to prevent the sewer gases from escaping into the home. After sealing that section of pipe, we removed the dishwasher and cut open the wall to expose the hole where the sewer gas was escaping into the home through the floor.

We will have excavation backfill the hole tomorrow, and we will also have them concrete the area that is missing concrete inside of the home behind the dishwasher. We will come back Monday afternoon to reinstall the dishwasher and verify everything for proper operation. We are also doing a little bit of work for free underneath the kitchen sink to address the cold side pressure issue that is occurring. Pictures of all work attached as well as videos.
