Looking at replacing my toilet with this model. Spec sheet says 5in height and 6 in from centerline of toilet. Looks like my supply is around 5 to 4 1/2 inches from centerline. Any idea if this will cause a problem with this model toilet? This is the first time I will be changing out a toilet and trying make sure I am not going to run into any problems before I buy this pricey of toilet. Thank you for any help.
