The Perfect Hydrant Replacement Solution for Any Situation

A Hydrant Assist Kit (HAK) is a frost-free water hydrant encasement system, which, once installed, allows a hydrant to be repaired or replaced from the surface—no need for digging or excavating. The HAK works with any waterline type or size, and at any depth! The HAK provides easy hydrant replacement in difficult areas, and can be easily maintained in a wide variety of applications. And there’s a HAK available to fit any water hydrant manufactured!
