Well component evaluation

The EGLE source water unit evaluates certain water well components pursuant to the Michigan Well Code. Pitless well adapters, well caps, and buried pressure tanks must be approved by EGLE before they can be used in a water well installation.

Manufacturers can request review and approval of their products by submitting the following:

  • Letter to EGLE source water unit requesting product review.
  • Product specifications, material or product listing under ANSI/NSF Standard 60 or 61 (where required), and detailed shop drawing of product.
  • Installation, operation, and maintenance instructions furnished to contractor or well owner.
  • Product sample (cutaway model preferred). Please indicate if you want the sample returned after our evaluation. If not, it will be retained for well training purposes.
  • Criteria for approval of water well equipment

    EGLE is responsible for evaluating pitless well adapters and units to determine if they comply with state regulations. Other equipment, such as well caps, hand pumps, and yard hydrants, shall be evaluated and approved prior to use in the state of Michigan.

  • Approved water well equipment

    The approval and listing of a product do not ensure compliance with the requirements of the Michigan Safe Drinking Water Act, 1976 PA 399, as amended, and the Administrative Rules.
