Hi all, I bought little white plastic shower heads at Lowes for under $3.00 a head. I usually take baths but when I take a shower I use that then unscrew it from the pipe and shake it out to dry and leave it off till my next shower. I toss it out after a few months and screw on a new one. When you unscrew it, you will notice how the water backs up after you shut off the water and sits in the pipe and shower head. Just an economical option.
