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!


Look at the Shu”t in Hebrew under the resources tab above. There are two Teshuvot dedicated to this question. If I still didn’t answer the question. Post the specific scenario more clearly.
Thank you
