Master bath tub leaks when used, filled tub 3 times and let drain, can see water dripping off of drain coming through sub floor from crawl space. Also found an angle stop leaking under tub valve in crawl space. This freestanding tub came with a pop up drain already installed and overflow already integrated for the drain assembly. We will remove the tub shoe, and replace parts as needed. We discovered that the overflow pipe is cracked, the manufacturer needs to be contacted for parts. customer will call us when contact has been made.
