Our plumbing product testing will ensure confidence, quality, and performance for your customers.

Full-Service Plumbing Fixture Testing & Certification Services

With a plumbing product testing and certification program that's been around more than 40 years, we have developed the capacity to test and certify the full range of plumbing products and fixtures against a comprehensive list of standards and model codes. Whether your goal is to comply with the building code, increase or maintain your quality control, or imbue your products with the consumer confidence and marketing benefits that come from certification by an independent third-party with a well-respected and recognizable mark, we’ve got you covered. As with all our testing and certification programs, you can expect rigorous, reliable testing protocols conducted by expert staff in our state-of-the art facility

Thermal Shock

To ensure a unit can withstand the typical changes in water temperature seen during everyday use, we test the fixtures by cycling hot and cold water for timed intervals at varying temperatures in our thermal shock machines.  

Wear & Cleanability

We use a Gardco WA-515001 scrub machine to pull a brush back and forth over a sample thousands of times and check it for wear and residual dirt build-up. This simulates years of cleaning and tests the product’s durability and cleanability under those real-world conditions.

Stain Resistance

We test samples to find out if common household items will stain by placing them on the product’s surface for extended periods of time within an environmental chamber and then attempting to remove them with a series of prescribed typical consumer cleaning methods.  

Ball Impact

To simulate common household accidents, such as dropping a can of shaving cream in the shower, our ball Impact test uses a steel ball dropped from varying heights to strike different parts of the unit. We then check for chips or cracks in the fixture. 


Because plumbing products may be exposed to sunlight throughout the construction process and/or through windows or skylights in a completed home, we test and certify the colorfastness of those products. Before a product can carry our certification mark, we expose it to 200 hours of irradiance using an Atlas Ci3000W Xenon-Arc Weatherometer and check for color change with a Colorimeter.  

Hair Entanglement

This testing and certification protocol ensures the suction fitting of a hydromassage bathtub does not present a drowning hazard, especially to children or the physically limited or impaired.
