I am installing a Delta 1748 and the instructions say there is to be a minimum of 8" with a max of 18" between the valve and the spout nipple. I am replacing an existing setup and the holes are already in the ceamic tile for the spout and valve. Unfortunately the distance between the outlet on the valve and the middle of the spout is approximately 5" My question is what kind of problems may I encounter with not having enough the recommended distance between the two. The diverter on the spout is a pull down style diverter if that makes any difference Thank you for your time
