I installed a Kohler HydroRail R-Beam (K-45212) with an 8" Round 2.5 GPM Rainhead (K-13692) and a Forte 2.5GPM Hand Shower (K-22165). The water pressure is just over 60psi. Overall a solid fixture and I like it. However when the diverter is up for the RainHead the HydroRail vibrates just enough that the audible hum/echo is annoying to me. There is no vibration with the diverter pointed down for the Hand Shower. There is also no vibration if I temporarily try a more basic, lighter weight showerhead in place of the Rainhead. I have called Kohler and their support seems awesome and willing to replace whatever I need.
On further investigation and testing it seems that the nature of the RainHead is causing the HydroRail to vibrate at or around the Showhead Adapter Assembly which is echoing somewhat through the rest of the piping. Not sure if this is a common issue with any HydroRail + RainHead, or if I should ask Kohler to replace the Showhead Adapter Assembly or the whole HydroRail?
