The flexible hose that connects the water line to the toilet tank broke. It is soldered on to the T-connector, making its replacement a little difficult. I turned off water to toilet and the main water line and started to loosen the T-connector nut to no avail. I then tried to loosen the nut that attaches to the copper water pipe from the wall. Thing I could get it off that way. It was tight, but then budged and now the problem is that it turns freely counter and counterclockwise without loosening or tightening. For reference, my set-up is similar to this picture except of course the line to the tank is soldered and not independently replaceable. Any suggestions will be appreciated.
