| Re: toliet doesn't fill up Hi Ron, The problem lies with the flapper. First check to see if you have cut off the ring on the end leaving you with two pieces with holes. If you have left the ring on that will stop thye flapper from seating correctly. Next you should have 1/4" of play in the linkage,(chain) when the tank is filled and the flapper seated. Also to insure a proper flush the water levelshould be about 3/8 to 1/2" below the top of the over flow tube when the tank is filled and the ballcock shuts off. Good luck Tom |
