BUYER BEWARE!  If you are using a Universal Toilet Supply Hose (7/8” x 3/8” x L), the instructions DO NOT TELL YOU that you will have to REMOVE AN ADAPTER  (see attached photo), which for some odd reason has been added to the underside of the tank, reducing the size to 1/2” instead of 7/8”!  We almost sent the toilet back since we were unable to attach our hose.  A hose for a FAUCET is 1/2” x 3/8” x L and shouldn’t be used for a toilet!  Otherwise, so far, we are happy with this toilet.
