We are looking at a property with a well and I have never had one. Can someone share with me what a minimum GPM would be? Two of us, and there will be a couple sprinklers. This will be primary residence.

I saw something in the pump house that said 6GPM I was not sure if this was the filter, pump, or a rating for something else (few things in there).

What is important to know about a well? Depth? Has it been re-dug to make it deeper? I've read http://www.wellowner.org/ so I have a brief under standing.
