When you’re in the field, you don’t have time to worry about whether or not your equipment will stand up to the job — especially if you’re plumbing behind a wall or underground. With hundreds of products and solutions to choose from, and just as many opinions from your industry peers about the right way to plumb, it can be challenging to figure out which method will work best for you.

As innovations are developed constantly in the plumbing industry, more and more contractors rely on the efficiency, versatility and durability of SharkBite fittings. With more than 1.5 million connections made each week, SharkBite has quickly become a trusted solution for a variety of applications. Every now and then, SharkBite get questions about proper installation and performance of its fittings in concealed spaces. This article addresses common concerns regarding SharkBite in these applications, and dispels some of the myths you may hear in the field.

Myth: “SharkBite fittings are only good for short term repairs and need to be replaced by permanent connections.”

Fact: SharkBite fittings are approved by the Uniform Plumbing Code and International Plumbing Code for permanent installation.

Properly installed SharkBite fittings provide permanent connections, backed by a 25-year warranty against any manufacturer’s defect as long as the item has been installed according to installation instructions and compliant with local code. SharkBite Universal fittings are specifically designed to ensure permanent connection, and aren’t intended to be disconnected and reconnected repeatedly. In fact, the only way to properly remove SharkBite Universal fittings is to use the SharkBite disconnect tongs and disconnect clips

Myth: “Don’t trust an O-ring seal in concealed space.”

Fact: Contractors who use SharkBite find it to be a dependable and safe solution in concealed spaces, including behind the wall and underground.

For example, Clint McCannon, owner of Cannon Plumbing, used SharkBite PEX and EvoPEX to repipe an entire home, with no concern about failed fittings or leaks. “I can put SharkBite fittings behind drywall, tile or beneath the floor and not have to worry about it,” he says about the installation. “I can sleep at night and I know my customers can, too.”

Another example of SharkBite’s behind-the-wall dependability comes from Larry Jones, owner and president of Universal Plumbing. When his crew renovated the plumbing in a 1950s home, they chose SharkBite Universal and PEX to do the job. Not only did the no-tools solution make the team’s job easier, but they also finished their project ahead of schedule and didn’t have to look back. Contractor Tim Redd says, “In the years I have used SharkBite, we’ve yet to have one fail. They’ve always served us well in what we’ve done.”

Myth: “SharkBite isn’t approved for underground and behind-the-wall applications.”

Fact: SharkBite fittings are IAPMO tested and approved for behind-the-wall and underground applications.

Current IAPMO R&T listing (File No. 4630) states: “Push fit fittings can be used in underground applications and as manufactured joints without access panels. To be installed in accordance with the manufacturer's instructions and the latest edition of the Uniform Plumbing Code and the National Plumbing Code of Canada.”
