Hello! Toilet hose nut(thread) leaking for half year. If water supply hose disconnected, no leak from tank. If hose valve shut off no leak. It just leak from the thread. It is no matter hand or wrench tightening it still leak! I replaced hose 3 times. I replaced wash on the bottom of tank too. Tape or No tape on thread it leaks. How do I fix it? Thanks
