1. Make a diagram showing the plumbing system of a four-room house which includes fixtures for the kitchen, bathroom, and laundry.
This diagram shows the pipes and fixtures involved in plumbing a typical four-room house.
2. Submit two pieces of iron pipe that you have threaded and connected with proper fitting.
Insert the correct size die into the die stock. Slide the die stock over the pipe and apply pressure with one hand. With the other hand, turn the stock handle slowly clockwise until the die has taken a bite on the pipe. Apply cutting oil to the die as the stock handle is given one complete clockwise turn and backed off a quarter turn. Repeat this action until 1/4 inch of the pipe is beyond the die stock. The pipe is now threaded properly. Turn the handle in a counterclockwise direction to remove the pipe.
3. Submit a repaired plastic (PVC), iron, or copper pipe, and tell how to repair all three.
PVC
Turn off the water, then cut out the damaged section of pipe using a hacksaw or a handsaw. Then clean the two ends of the existing pipe thoroughly and let it dry. Cut a new piece of PVC pipe the same length as the damaged and removed piece and make sure it is clean too. Apply PVC primer and cement to the ends of the replacement pipe and slide couplings over them, one on each side. Then apply PVC primer and cement to the existing pipes, and join them together. Let the cement cure for the amount of time indicated on the can. Finally, turn the water back on and check for leaks.
