	Use Existing Casing - Plastic or Steel low cost and most of the advantages of pitless units.

	Benefit - No restriction on casing material.

	Heavy Duty Galvanized Iron Support Bar holds 160% more weight than aluminum support bars by others, more weight than slide together type pitless adapters. It also minimizes danger of losing pump or pipe down well. The weight of the pump, pipe, and water is supported by the bar which uses the top of the casing, not just a small part of the side wall like pitless adapters. Merrill support bar also has a ground screw.

	Benefit - Safer and holds more weight, if any questions on weight limits for MCK Series - Call Merrill.

	Water System Easily Drained by turning the stainless steel screw inside pull pipe so entire water system outside well could drain without pulling the pump, impossible with most other pitless kits and pitless adapters.

	Benefit - Simple answer to draining or seasonal use.
