A super wingnut makes it easy to adjust the height of the bladder. 800/452-4902;


Manhole liner

CIPMH (cured-in-place manhole) liners for chimney or full-depth manhole lining from LMK Technologies eliminate infiltration and inflow through manhole walls. The universal-sized manhole liners resist freeze-thaw cycles and create a watertight, corrosion-resistant structural lining. The liners fit all manholes, including barrel sections, eccentric and concentric cones constructed of brick and mortar, precast, or block.

Site preparation and installation can occur in the same day. Once the liner has been vacuum-impregnated and manually inverted, the liner cures under ambient temperatures in one to two hours. 815/433-1275;


Cleaning nozzle

The Alphajet nozzle from USB-Sewer Equipment Corporation is designed to clean grease, sludge and crusts from lift stations and manholes prior to rehabilitations. The nozzle is actuated by water from the pressurized hose of a jetter truck. Four driving nozzles cause 360-degree controlled rotation in a horizontal plane, which eliminates the need to cover the manhole. The horizontal rotation allows for observation of the cleaning progress. The body requires no lubrication or replacement of internal mechanical parts within the first 12 months of operation. Driving nozzles can be extended to accommodate various sizes of manholes/lift stations. 866/408-2814;


Drop bowls

Inside Drop Bowls from RELINER/Duran eliminate outside drops in manholes and clean up failed inside drops. When used in wet wells to eliminate uncontrolled drops, they prevent pump cavitation, prevent aerated influent from being drawn into the pumps and increase pump life. Made of marine-grade fiberglass, the bowls are simple to attach to the manhole wall with stainless steel expansion bolts.

By providing easy cleaning and inspection from grade level, maintenance time and cost are reduced and their compact, low profile provides full access to areas below.
