The difference between cast iron soil pipe and plastic is easily understood when it comes to sound. Cast iron drain waste and vent pipe systems are superior when it comes to sound attenuation. For commercial office buildings, hospitals, high-rise condominiums or high-end hotels, no one wants to listen to the flowing of fluids when a toilet is flushed from the floor above.

Specifying cast iron for waste piping provides a plumbing system that is up to 11 times quieter than an all-plastic system. This is how it got its name – the Quiet Pipe®.

A primary factor in cast iron’s sound-dampening quality is its microstructure. Graphite flakes absorb and dampen vibration applied to the iron. The microstructure isn’t the only advantage when it comes to noise.

Cast iron installation plays a primary role in sound attenuation. The use of neoprene rubber gaskets to join sections of cast iron pipe provides additional sound dampening. Sections of pipe do not touch as the rubber gasket creates a buffer, and so contact-related sound is eliminated. In contrast, plastic systems are installed as rigid systems that are solvent cemented. Noise is created as the rigid system expands and contracts with heating and cooling.

A frequently used tactic attempts to create a solid barrier between the pipe and the wall: wrapping plastic pipe in insulation to muffle the sound of rushing water and fluids through pipes. An insulated plastic pipe, however, can be sound-enhancing rather than sound-deadening. The “fix” results in additional installation costs incurred for both product and labor.

This is the first of McWane Plumbing Technical Services ‘How-To’ video series to learn more about cast iron soil pipe and fittings.

McWane Plumbing Technical Services is a full-range service organization that provides educational and technical support on codes and standards as well as regulations that cover cast iron soil pipe and fittings, gaskets and couplings, and drainage products for storm and sanitary drain, waste, and vent (DWV) plumbing systems. This service is provided at no cost. Tech Services plays an active role by offering assistance to those interested in better understanding the benefits of using a cast iron plumbing system in a building application.

The Plumbing-Heating-Cooling Contractors — National Association’s (PHCC) Educational Foundation is proud to announce the winners of HVAC Apprentice Contest Winners the national plumbing and HVAC apprentice contests.

The contests were held October 10^th & 11^th in Albuquerque, N.M. on the tradeshow floor during the PHCC—National Association’s CONNECT 2018 event. A total of nineteen plumbing and ten HVAC apprentices from across the nation took part in the contests.

• 1^st Place: Josiah Tiegs, McDowall Comfort Management in Waite Park, Minn., Sponsored by Brasscraft Manufacturing
• 2nd: Daniel Deneve, GSM Services in Gastonia, N.C., Sponsored by NIBCO
• 3rd: Jeffrey Deuel, American Mechanical Services in Denver, Colo., Sponsored by Milwaukee Tool

Plumbing Apprentice Contest Winners

• 2nd: Kyle Mao, Lange Plumbing in Las Vegas, Nev., sponsored by AB&I Foundry
• 3rd: Steven Kroope, Deluxe Plumbing & Heating in Bethlehem, Pa., Sponsored by Reed Manufacturing

The HVAC competitors were required to complete a written test, demonstrate proper brazing techniques and perform a hands-on diagnostic on an HVAC package unit, with system errors created by the Foundation’s contractor volunteers for the competition. The competitors also had to perform a pressure and leak test, demonstrate proper refrigerant recovery procedures and the ability to accurately take a variety of instrument readings.

The plumbing apprentices were required rough-in a bathroom system. The set-up includes a toilet, sink and shower, complete with supply, waste and vent lines, plus cleanouts and extra features designed to test the contestants’ knowledge and skills. The test set-up includes a variety of pipe materials – cast iron, copper, PVC and PEX, and corresponding joining methods.contractor volunteers for the competition.

A dedicated team of contractor volunteers arrived two days before the competitions to assemble the competitor test benches, distribute the materials and supplies and setup the testing areas. They monitor the competitions, evaluate the apprentices’ work and provide constructive feedback on each competitor’s performance following the event.

The contests are made possible by the generous support of several industry sponsors who provide monetary support and in-kind material and tool donations. Sponsors for the 2018 competition included, AB&I Foundry; A. O. Smith; Bradford White Corp.; BrassCraft Manufacturing Co.; Copper Development Association, Inc.; Daikin; Delta Faucet Co.; Emerson; Fluke, Greene and Associates; IPS Corporation; KOHLER Company; Mechanical Hub Media; Milwaukee Tool; NATE; NIBCO INC.; Oatey; R.E.C. Industries; Reed Manufacturing Co.; RIDGID; State Water Heaters; Tyler Pipe & Coupling; Uponor; Viega, LLC; and Zoeller Pump Company.

Milwaukee Tool made a major contribution to the Plumbing Apprentice Contest this year by donating twenty of their M18 Force Logic Press Tools and jaw kits, with a retail value exceeding $60,000 total. This gift allowed the competitors to gain experience and prove their skill with making press connections during the plumbing competition and will be used in future competitions as well.

Fourth year apprentice, Chris Pinette with E.H. Marchant Co., a union contractor through the local 12, based out of Quincy, Mass. was sponsored by Mechanical Hub Media.

“These contests are an incredible demonstration of the opportunities that exist because of the Foundation,” reports Foundation Chair Craig Lewis. “You have these amazing apprentices from all over the country coming here to show off their skills. The sponsors are so generous with their support. And then our volunteer committee members and staff are pulling it all together in a new exhibit hall every year. It really is quite a thing to see and I’m very proud everyone involved with these competitions.”
