Backflow Inspection & Test Tags

Request a Quote


Backflow tags are an important tool for maintaining backflow inspection records and test results. Our custom backflow inspection tags are designed to your exact specifications and built to last in tough conditions. Tags are made with water-resistant Tyvek material, reinforced eyelets and metal stringing. They can be customized with a company name, logo, contact information, emergency procedures and more.

When drinking water piping connects to various plumbing fixtures or water lines, a cross-connection is created. Contamination can result when a backflow event occurs if improperly connected, allowing contaminates to reverse flow from the fixture or equipment back into the drinking water. Backflow preventers should be well maintained, inspected and tested regularly to avoid contamination.

At St. Louis Tag, we take pride in fully customizing backflow test tags to customer requirements and specifications. We can also guide you through the process and make recommendations for your industry needs. View our custom tag services page to see our full list of capabilities and request a free quote today.
