Customer is in the due diligence period for buying the property. Got customer approval to pull a toilet and run a camera. Camera made it about 50 feet into the yard before it could no longer be pushed. Observed channeling in the cast as well as pipe deterioration. Made notes of this and pulled camera back and attached inspection video. Left price to cut in a cleanout and perform jetting and camera work to price full line replacement. Left price to replace cast in the crawlspace as well as a price for water heater replacement due to age of existing heater.
