I’m in a very old house with a Clawfoot tub that’s about 16 inches away from a side wall and this is wasted space so I’d like to move it over. However, i want to avoid digging the concrete to move the plumbing over. Since they’re exposed anyways is there any way I can simply lengthen the drain segment from the T pipe and use a flexible overflow pipe and leave the in-floor drain as is?
