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.
It sounds like he removed 3in waste water piping. Copper is worth what the price per pound is right now in your area. I think it is under a dollar per pound right now. But still that 3in pipe is nice scrap.It adds up quick. am having my bathroom redone and my plumber has removed some copper pipes (which are about 40 years old and have some green spots on them) and replaced them with all plastic. What I am wondering is about how much would a piece be worth, one that he took out was about 5 feet long and about 3 inches in diameter.
