Seat pops a lot when I sit on it.  The seat was installed perfectly but overnight the very strong flexible hose flexed back to shape and worked the connector at the bottom of the bowl loose and it leaked so much it went under the wall into the next room’s carpet before we found it.  Spent hours drying the carpets.  Works fine for family even without heated water.  Texas summer though.  We will see during winter.  Haha.
