I have a Kohler single handle kitchen fosit that was leaking verry bad. So I took the handle off and tightned the fosit... it was loose and would turn all the way around if the wall was not in the way. So I tightned everything down. When I turned the water back on there was no pressure. So I loosened everything just a bit... I thought I might have made it to tight. Still no pressure. Any suggestions?? Thank you :confused::rolleyes:
