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.
Step 1: Gathering Parts and Tools
You basically need a T fitting to connect into the toilet supply, a check valve, an isolation valve, a kitchen sprayer, and nipples and fittings to connect all this together.
I ended up with this
three ½” close nipples
two 1” bell hangers
¾” bell hanger
Sink sprayer (from an old sink)
Add-a-valve fitting (Watts part #BPAV-666)
â ” compression nuts (Watts part # A-104)
â ” OD to ½” FIP reducing fitting (Watts part # A-118)
½” swing valve
½” check valve
½” FIP to â ” FIP reducing fitting (Watts part # A-828)
¼” close nipple (Watts part # A-740)
2 feet of polyethylene tubing, â ” OD, ¼” ID
The tools I needed for this project are
Channel lock pliers
Phillips head screwdriver
Utility knife or tubing cutter
