You are probaly right about "pressure vs flow" but I am not a plumber,
just a guy trying to get more water out of the shower. The flow of
water out of the shower appears that it is running on low and not high,
based on how the flow is out of the other facuets. I did change shower
heads because the removal of the flow restrictor from the first shower
head made no difference. Guess I could buy shower heads until I find
the one I like but that could end up costing a lot of money.
I much prefer the suggestion that the flow control may be partly
clogged. Think I will go after that one and if it doesn't work, learn
to live with what I have.
