Measure the inside diameter of the supply pipe leading out of the wall to the shower head.


Get about half a dozen five cent metal washer with the correct outside diameter but varying hole diameters. Install one between shower head and supply pipe.

Still too much pressure, go to smaller hole. Too little pressure, go to larger hole.

Actually, it's best to get used the the high pressure. It's great in the morning.

Also, 80 PSI is fine. Should be no trouble with appliances.
