This DIY will show you how to build a higher quality (and safer) diaper sprayer than the commercially available units for the same price or even a bit less.
A diaper sprayer is basically a sink sprayer connected to the toilet which allows you to spray the poopy mess into the toilet while keeping your hands cleaner than the old dunk and swish technique. Many of the commercial units are just a sprayer tapped into the toilet supply.
My improved design has a shut off valve to take the pressure off of the sprayer when it is not in use and a check valve to prevent fecal contamination of your household water supply. This assembly uses a length of tube so that it can be mounted away from the existing toilet supply valve. The remote installation ensures that when you turn the valve several times each day, you are not transmitting forces to a valve designed to be used a few times per decade. The entire thing is mounted to the wall using bell hangers.
