Steps you should take if your toilet is leaking at the coupling nut
Here are some steps you can take if you notice leaking at the coupling nut of your toilet:
Is the coupling nut touching the locknut? If yes, the tank may be thicker than most. There are two immediate solutions without replacing the water supply or the fill-valve.
- Use a flat file on the top of the coupling nut. File 1/8” off of the nut. Then install.
- If the coupling nut is not a part of a stainless steel or vinyl connector, you can place one or two stainless steel metal washers under the cone washer and then install.
