I have a single handle Kohler showerhead that is only about three or four years old. Recently, the pressure has dropped dramatically when the water is turned on. No other faucet in the house is having a problem. It is only that one showerhead. Any ideas?

First remove the shower head from the chrome pipe and turn on the water. Strong stream now? If so the shower head is blocked. See if there isn't a small neoprene washer with holes around the edge. That's a water saver. Pry it out and toss it. If the shower head's still blocked try soaking the shower head in CLR overnight. If that don't get it click om back and we'll go to plan "B" Regards, Tom
