The ASSE Product Listing Program is an ANSI-accredited third-party certification body with more than 3,000 products and models listed.

When plumbing system designs and codes require products that are in compliance with ASSE standards, code officials, designers, specifiers, contractors and inspectors need verification.

To make life simple for all users, plumbing component manufacturers choose ASSE’s Product Listing Program ... verification is easily spelled out on the product.
Look for the seal.

Only those products that have been tested by an independent ASSE-accredited testing laboratory, have been reviewed by the ASSE Seal Control Board and have been found to be in compliance with the appropriate product standard can display the ASSE Seal.

If your code requires an ASSE listing, be sure that the product displays the ASSE Seal.
