The MANTA Series Bottom Cleaner from NozzTeq is recycled water friendly, with interior surfaces and interchangeable rear jetting plates made of stainless steel and ceramic parts to stand up to hard water and grit. It is more than 50 pounds, and slides on wide runners that are replaceable. It is designed to stay on the bottom of large-diameter pipes for effective jetting, and the nozzle doesn’t wear out. The jetting plate is also interchangeable and replaceable, and plates come in eight-, 10- and 12-jet configurations. 866/620-5915; www.nozzteq.com; Booth #1454.
