I arrived to the customers home and they had another plumbing company come out and diagnose a faulty wax ring, and set up a water restoration to be performed. The next time that the tub was used and drained all the water went through the ceiling below and caused water damage to the customers home.

The customer was given two options to have cast-iron work performed with replacing what is accessible by cutting sheet rock and within the walls for two bathroom groups
