Refrigerator water dispenser keeps dripping after use

A few drops right after dispensing is normal. Longer dripping is usually trapped air in the lines after a filter change or door removal, which pushes water out as it expands. If purging does not help, check filter seating, levelling and the inlet valve.

Refrigerator water line and ice maker hookup

Run a 1/4 in supply (copper or a PEX kit made for refrigerators) from an accessible shutoff to the fridge inlet, leave a service loop so the fridge can be pulled out, flush the line before connecting and flush the new filter afterward. Avoid self-piercing saddle valves where code or the manufacturer discourages them.
