The water wasn't filling up all the way in the bowl. Only 1/2 way. So I went to Lowe's & replaced float & refill valve/line. It was too short in the beginning & water was just filling up 1/2 again in bowl. I've read the instruc. Again & it said that I need to make it taller so I've done this & now the tank won't fill up with water. There is no water coming from anywhere!:confused:
