Got an interesting one here. I was working on a bath/ shower with a American Standard two handle (3275505.002) with low water pressure and have tried everything I can think of to get pressure back. At first I thought easy fix swap about the valve cartridges and flush multiple times and I should be good to go. That did not work. Water pressure increased slightly. I know that there is plenty of water pressure from the hot and cold supply as water shot across the tub on both hot and cold with the valves out. I thought the pipe going to the tub faucet might be clogged with rust but it can't be. I pulled the plunger for the shower head and pressure built slowly and once pressure had built I pushed the plunger down and water came flowing out quickly which tells me this pipe is fine. Water flows equally whether just cold is on or just hot or both. Does this mean there is a clog somewhere in the rough in and if so how can this be remedy.
