Service for toilet replacement: arrived to home to find that toilet was flushing. Arrived and found that toilet is an 18 inch rough toilet. This means that the toilet flange is 18 inches off wall. Explained to customer how we would have to special order new 16 inch rough toilet to make this installation work. She stated I had to call John and tell him. I tried calling customer 3 times. Customer never answered. We will need a half deposit to order toilet and come back to install new toilet. We will have to return to install toilet once we have material and customer gives Approval. All working properly at this time.
