The AQUA-MAX APB 30 pressure booster from AquaMotion is designed to provide increased water pressure at all fixtures and sprinkler heads (30 psi). It automatically starts when water is drawn and stops when demand ends. No short cycling increases pressure after water demand ends. It offers simple installation, plumbing into incoming waterline and plugs and a 115-volt wall fixture. Its compact design makes installation easy, and it offers quiet operation with a totally enclosed fan-cooled motor. Its stainless steel construction offers corrosion resistance and reliability. It has a composite control with reinforced brass connections, a built-in check valve that eliminates backflow of cold water to the main, and a mounting base that can be attached to the floor or wall. Enclosures for the control and motor are sealed to prevent water entry. Drain and fill plugs enable quick filling and venting. 401-785-3000; www.aquamotionhvac.com.
