Biffy Universal Bidet - Easy 3 Step Installation   Your new Biffy Personal Rinse is very easy to install on just about any short or elongated toilet bowl. Just follow these simple steps...   Step One Remove the toilet seat using a standard flathead screwdriver and pliers. Step Two Position the Biffy on the rim of the toilet bowl and replace the seat. Align the Biffy bracket with the left toilet seat hole. The spray arm will rest inside the toilet bowl rim. Place the spacer over the right seat hole and replace the toilet seat. Replace the toilet seat bolts. DO NOT OVERTIGHTEN! Step Three Connect to the water supply. Turn off the water supply at the wall. Unscrew the water supply line and insert the Biffy T-adapter between the tank and the supply line then tighten all fittings. If the water supply line is too long, cut or replace the line to an appropriate length. That's all there is to it! You're now ready to enjoy your Biffy.
