Bob reviews the work done on the existing plumbing once all the waterproofing and flood-prevention measures are put in place in the basement. Al Leone of Leone Plumbing Corp. first cut the pipes into sections for easy removal. The cast iron pipe was cut and removed using a special pipe cutter. Bob explains that Leone is a union contractor who decided to go into business for himself. His helper, Matthew Orlando, is going through the apprentice training program through the Plumber and Gas Fitters Local Union Number 12 in Boston. The chapter spends $4,500 a year to put each apprentice through a thorough five-year training program where they spend two nights per week learning about everything from bathrooms to hospital gas work. Leone demonstrates some of the specialized work he does to install the pipe, including using oakum, a joint runner, and poured hot lead to form a joint seal. Leone then shows how some of the other seals are put in place in the pipe. Al Leone of Leone Plumbing replaces the old brass water pipes with PEX tubing in the Melrose basement project. Leone explains that the water hammer will be removed as it is so old it is obsolete. Leone cuts the pipes into sections for easy removal. The brass pipe dates back to when the house was built and is corroded and thin from years of use. The proper length of tubing is pulled and held in place by a bend support. Bob explains that by using PEX tubing, more headroom is created in the basement and the sink and laundry lines can be easily relocated. Kyle Tasse of Viega North America shows Bob the three different types of PEX: Pexcel for plumbing, Pextron for heating, and Fostapex for both plumbing and heating. According to Tasse, the advantage to Pexcel is the connection system that features a sleeve with an eyehole for double checking that the sleeve is securely on the tubing. The fitting holds the sleeve in place so that the lines can be dry fitted and attached later. Bob points out that innovative technology is exciting for do-it-yourselfers, but it is often best to hire a master plumber.
