Water pressure in shower
In 2009 I had my dream bathroom built. (A complete addition to the house). One overhead shower head, a handheld (separate diverter) and 2 body sprays at the back of the shower. All Kohler. The first time we used it no water pressure out of ANY of the heads. We took the main one back to the supplier and she gave us a much less expensive one and said; "new plumbing supplies today all have water savers in them" This one will work. And it did. We never were able to use the body sprays as only a trickle comes out. The handheld would work; but would decrease the water in the overhead even on a separate diverter. So since 2009 we have used only the main head. At some point in the past 4 years we had a myriad of people in and they all said; you need a "booster" on your well. We did not want to spend the $2k unless it worked. One company sent a plumber with the booster. He hooked it up at the well pump and it made no difference whatsoever. He shook his head and left. So here I am with a $50k bathroom addition no better than a shower in a cheap motel.
I am attaching some photos I took when the install was going on. Any ideas will be appreciated.
