Hi Rabbi Abadi,

I understand that permanently installed pipes are considered part of the ground. But if a movable metal kli is later permanently attached, does it lose its status as a kli?

Also, in countries like Norway, where much of the drinking water comes from natural lakes and rivers, could tap water be used directly to establish a kosher mikveh? Or would the municipal pumping and storage systems make it mayim sheuvim?

Thank you!
