Customer called us out because a toilet in the upstairs bathroom overflowed all over the bathroom. There’s a major clog in the toilet drain. I will have to pull the toilet and remove the stoppage and reset the toilet verifying that there are no leaks and that everything is draining properly. I was successfully able to remove stoppage. I tested it by running Lots of water. The customer does have very old cast-iron pipe and so we have scheduled for a camera technician to come and do an inspection tomorrow 9 AM to 11 AM Everything is draining properly at this time. Customer is very satisfied. I also provided the customer with our ENDURE drain maintenance product.
