The basic components of procedure trays include, at a minimum: items for skin preparation; Items for draping; supplies to give local anesthetic; items for surgical closure. Skin preparation items would include 2x2 or 4x4 non-sterile gauze sponges or 6 cotton-tipped applicators that can be used to prepare the skin with an antiseptic solution. Usually the gauze are picked up by a sponge stick and used to paint the antiseptic on the skin.
Water Supply. The supply line to the toilet is standard 1/2-inch copper pipe. This standard is used throughout the home to supply faucets, showers and any other appliance requiring water, including the washing machine. This 1/2-inch pipe connects to the home's 3/4-inch water pipes. The water supply line does not run directly to the toilet, however.
When you have the PEX cut to length, slip a copper crimp ring onto the pipe. Insert the tubing into the piper fitting. It should bottom out on the shoulder of the fitting. Slide the copper crimp ring up so that it is 1/8 to Â¼-inch away from the tubing. Crimp the copper crimp ring with the ring crimper, insuring that the crimper is at a 90 degree angle from the crimp ring.
