I have a claw-foot tub...the drain goes on the outside, straight down into the floor. The constraints in our house require us to move the tub about 7' away from the drain. I need something to connect to the bottom of the drain, bend 90 degrees, go straight for about 7', then bend down to the floor drain. Can anyone come up with something that will work with the old brass stuff? I can raise the tub about 3" off the floor to create more room. Thanks, Grampom
