Answer:

Home depot plumbing dept and electrical dept have it. Use the thick steel pipe that can stand over 500 psi. To solder copper thin pipe,use a torch and flux found in plumbing dept. Very cheap and easy to use with a few practices. To seal the threaded pipes, use white tape sold in plumbing dept.
