I heard about this type of drain for my sister. The salesman who helped me with my order was 5 stsr. So helpful in every way. Unfortunately my contractor had already put pipes in that didnt fit in some way. Not your product.
I went online to return it. Again an easy and helpful process. I think the contrator did not know the procedure and we had to get my project over.
It seems you have a great company and from start to finish you have your procedures down, have hired great staff and have a great product.
