This toilet was running after it was installed.  Customer service recommended rinsing something in it and it is no longer running.  They also sent a replacement part which we have.  The man who installed it said he'd installed hundreds of toilet and never had to do that.  Now that it is working we like the toilet.  It indeed is high.  I am a large lady so the flesh on my legs gives me height.  My daughter said her feet do not touch the floor.  My husband is 6'4" and he loves it.  For me it is hard to stand so the extra height is a godsend.
