Review on Maximize Shower Pressure with 3 Inch High Pressure Shower Head - Wall Mount, Chrome, 2.5 GPM - Ideal for Low Flow Showers! by Victoria Scholten

I have replaced our single shower head with 2 by adding a dual outlet manifold https://www.amazon.com/gp/product/B00XZXANBA/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 2 shut off valves https://www.amazon.com/gp/product/B00XVS17PA/ref=ppx_yo_dt_b_asin_title_o00_s01?ie=UTF8&psc=1 as soon as they arrive in a few days. Shut off valves are not required unless you want to be able to shut off individual shower heads. I did not remove the water restrictors to see how they would work once installed. You are wonderful. Restaurateurs will not shoot. We have a tankless whole house hot water system that can produce 8.9 gallons of hot water per minute but reduces water usage to keep up with demand. He had no trouble getting water while turning on extra faucets for testing purposes. I tested it because these two heads put out a lot of awesome high-pressure water together. For reference I can tell you that our water pressure valve in the main house is set at 65psi. I replaced our single shower head without telling my wife and just showed her the new doubles when she got home from work. I told her to jump in and shower while I finished dinner. When she came down to dinner and said 4 words. This shower was amazing! Mission accomplished.
