This estimate includes the removal and disposal of existing sections of the affected cast iron. This will be replaced with PVC, properly secured and we will ensure the proper fall (flow) exists. All the cast-iron about 30 to 40 feet was improperly installed with no proper incline which Is causing the water to backflow in the other direction. Due to the other technician breaking his equipment, we will not be sending down any of our equipment down that pipe due to risk of Breaking. Customer pay balance with same credit card
