For this evaluation I showed up to the customer home and water was under the system leaking. The primary journal line was clogged where it meets the house plumbing as well as in the p-trap. I cut the primary drain line at the end where terminates and at the pizza and unplug all of that and also tested it out by pouring three bottles of water into the pan and it drained with no issues. The connection point where the primary meets the house plumbing is backing up and was overflowing so the customer will need a plumber to snake that pipe and unclog it.
