Running toilet — check the supply valve for drips after a fix

After a running toilet repair, the shutoff valve behind the toilet gets turned off and back on. Older valves sometimes start a slow drip at the stem when they move.

Give the toilet supply valve a quick drip check

1. Open the supply valve fully, counterclockwise, until it stops.
2. Wrap a dry tissue around the valve stem and the line nut and wait a few minutes.
3. If the tissue stays dry, you are done.
4. If it is damp at the stem, snug the small packing nut behind the handle about an eighth of a turn. If it still drips, call a plumber.

That is the beat. Do not crank hard on an old valve.
