St. Louis Testing Laboratories Incorporated, an independent chemical, mechanical, and environmental testing service, recently examined and tested PVC Spray ‘N Lock to determine its impact on the potability of pipe water … and we’re very excited (and exceedingly proud) to say that it passed with flying colors!

Scientific testing  (ASTM D3452-06(2017) and analysis proved that PVC Spray ‘N Lock does not negatively impact the potability of water run through a system. Plus, the lab also pressure tested PVC Spray ‘N Lock’s strength; it held up to a whopping 215 psi!

The lab followed strict testing protocols as set forth by the American Society For Testing Materials (ASTM). They purchased a length of  3/4″ potable water PVC pipe and elbow fittings, cut two lengths of pipe and bonded them to the elbows using PVC Spray ‘N Lock. The pipe was rinsed with tap water for one minute. The rinse water was collected. They then rinsed the pipe for another 15 minutes and again collected a sample of the rinse.

According to the report, the two rinses were analyzed using Pyrolysis/Gas-Chromatography (Pyrolysis is the thermal decomposition of materials). The rinses were individually dropped directly into a micro-furnace capable of 1050°C. The analysis of both did not detect the presence of Spray-‘N-Lock’s ingredients.

The lab’s official determination is that PVC Spray ‘N Lock did not negatively impact the potability of water purged through the system.
