Why does a product need to be accepted by both Massachusetts and a National Testing Laboratory?

The Massachusetts plumbing code requires that only products and materials approved by the Board shall be used for plumbing and gas fitting work in Massachusetts.

If I cannot find a product's manufacturer or a model number, does that mean it is not approved?

If the product you are searching for is not being displayed on the search result page then it is not approved to be used in Massachusetts.

If a Manufacturer has some models approved, does that mean that ALL their models are approved?

No, only the products listed on the search results page are approved.

What is an expiration date and if a product has an expired date can it still be used?

The expiration date is used to keep a track of possible failures that may occur with a product during a specific period of time. Products that have an expired date can not be used.

Does product acceptance endorse the use of a Manfacturer's products?

Important note: Product acceptance is not an endorsement for the Manufacturer, it only implies that this Manufacturer product(s) meet Massachusetts’ Codes (more information). You can use any Manufacturers products that have been approved by the Board in Massachusetts.
