Customer called John the plumber out today because the unit below him is complaining about a water leak coming from above the guest bathroom toilet. Customer had a similar issue a few months ago, and that issue was resolved by replacing the toilet flange and wax ring. Unfortunately, this is not a similar issue due to the fact that there has not been anyone living in that unit for at least two weeks. And technician did not see the toilet running. So the leak may be coming from somewhere else. Technician gave the customer some options on a leak search but before a customer goes through with that option, customer would like to put dye in the toilet to make sure that it is not the toilet causing the issue.
