shower heads and sink faucets too...
I have an illegal shower head. (I know I am an outlaw!) flows 3 gallons per minute.. I can shower and be done in 2 minutes if I want.. rinsing is not a problem :)
I de-gored my sink faucet too.. I got sick of waiting over a minute to fill the darn dog water dish.
I drilled out the restrictor to increase the shower flow.
My son always comments on the quality of the shower when he comes to visit.
