New tests prove UFV’s a sound choice for future plumbers

New tests prove UFV’s a sound choice for future plumbers

As far as working relationships go, you could say UFV’s connection to Ipex is as solid as a cast iron pipe.

Or better yet, XFR.

Don’t worry if you don’t know the latter, it’s still new in the plumbing world ­— but it could be coming into walls and floors around you following a study conducted by plumbing and piping students inside UFV’s Trades and Technology Centre.

Using a mock-up two storey structure — erected four years ago by construction students inside the plumbing department — UFV students created three identical toilet plumbing scenarios using three different pipe materials:  Acrylonitrile butadiene styrene (ABS/plastic), XFR (a new PVC), and cast iron.

While ABS is light, it’s not fire rated like the other two. Traditionally, cast iron is used for main plumbing pipes, as it’s solid, quiet, and fire rated. But a new product, XFR, is coming into the industry.  Lighter, fire rated, and easier to work with than cast iron, the only question remaining is how much noise is generated when water rushes through.

To answer that, UFV plumbing and piping instructor Rod Smith set to work with Ipex, a maker of thermoplastic piping systems. Using the three identical toilet scenarios throughout April, students measured sound of water flushing through ABS, cast iron, and insulated XFR.

This summer, Ipex is coming to UFV’s Trades and Technology Centre to conduct their own sound study using decibel measuring devices even more sensitive than UFV’s machines, which found ABS levels to be about six decibels louder than cast iron and insulated XFR, which were both equally quiet.

“We’re helping out the industry,” Smith explains.

“We want to know which was better, cast or XFR. What we’re doing is giving our students a head start on a new product.”

UFV’s relationship with Ipex goes back several years, with the company providing regular tours of its Langley facility to give students a better understanding of materials they’ll use throughout their careers.

”It’s been a good relationship,” said Patrick Maguire, Ipex technical services representative.

“Ipex is always interested in expanding the knowledge of people in the trade.”

Buoyed by decibel tests that could reveal what’s coming down the pipe, it’s safe to say UFV’s plumbing students are flush with answers like never before.
