So after 3 weeks of always returning the handle on the faucet to the hot side and having 3 weeks of no drips, Yesterday there were around 6 drips in the catch pan that I place in the sink to log any dripping.
Every day during this time period, when switching on the cold water, there would be air in the line. So I switched on the hot water, and guess what, there was air in there also. So I ran both cold & hot and shut it off with the valve in the hot position.
This morning I checked the catch pan, it was dry ??????? Wierd
