Seems to me that flow restriction would create a back pressure in the plumbing upstream of the shower head which would be greater than a free flow head. In particular, a leak could be created at the gooseneck connection behind the wall, which would be undetectable until major damage has been done to the structure in the wall. Would removing the flow restrictor device or using a non flow restricted head help. It would provide a more pleasant shower. But that's just me.
How would one go about removing the restricting feature if I wanted to go that route?
Thanks in advance for any knowledgeable responses.
