Inside Drop System offers advantages over interior tee fittings and outside drops
Sewer drops in manholes have traditionally been constructed using a variety of techniques that have proven troublesome over time. The RELINER®/Duran Inside Drop System was designed to address previous issues and control flow using simple, cost-effective, readily available components. The system consists of a fiberglass Drop Bowl that is bolted to the manhole wall just beneath the high-level inflow pipe. Stainless-steel pipe support brackets are used to attach the drop pipe to the wall.
The RELINER/Duran Inside Drop System was designed to control flow using simple, cost-effective, readily available components.
The Drop Bowl does not touch the incoming pipe, and protrudes minimally into the structure. The resulting drop pipe is just off the manhole wall and securely fastened. A flexible coupler is used to connect the drop pipe to the Drop Bowl, and a bend is installed at the pipe base in the manhole invert. An optional force line hood is available for high-velocity applications.
The system is easy to install and allows the drop to be cleaned and inspected from above. Accommodates internal drops ranging from 4” to 24” in diameter. WW
