DISTRIBUTION BOXES

Overview

DISTRIBUTION BOX

American Distribution Boxes are made of high-density polyethylene for years of dependable use. They are non-corrosive, strong, and lightweight for easy handling.

Inlet and outlet elevations are positioned to provide equal distribution and meet most local codes.

Twist and lock 4” pipe seals and plugs are easily installed and fit all 4” plastic pipes.

Precise leveling is simple with the addition of our patented Dial-A-Flow™

GRADE ACCESS RISER

The Distribution Box Riser is made of high-density polyethylene and is easily assembled for installation.

Risers can be provided as both gas and watertight. It also screws into the lower unit with stainless steel Phillips head screws.

The 14” riser allows at-grade access to the Distribution or Dropbox for inspection and leveling.

Each riser is provided with an anti-flotation adapter flange. An optional stainless steel screw package fastens the lid to prevent tampering or accidents.

DISTRIBUTION BOX SEALS

For standard installation instructions, reference the American Distribution Box Installation Instructions.

Due to the unique twist-lock seal design, the seals may be easily adapted for increased head installations by simply applying a sealing compound to the surface of the seals.

For smooth walled installation with an increased head, select the proper seals for the box/pipe configuration. Place a bead of asphalt-based sealant where the seal lip contacts the box. Insert the seal into the box opening, then twist and lock each seal.

For corrugated pipe installation with an increased head, select the proper seals for the box/pipe configuration. Place a bead of asphalt-based sealant where the seal lip contacts the box. Insert the seal into the box opening, then twist and lock each seal. Cut the corrugated pipe to receive an American Dial-A-Flow™. Compress the first three corrugations of the pipe and insert the pipe into the box seal. Lock the pipe and seal at first corrugation. Expand the pipe to its original shape. Place a bead of sealant around the pipe and seal connection, and wipe around the pipe with a gloved finger.

DROP BOX

Drop (serial distribution) box inlet and outlet are positioned to meet local code requirements. Leveling or flow control can be done with the American Dial-A-Flow™.

SAMPLING CONTAINER

The American sampling container provides a simple non-corrosive method to sample wastewater. This grade-level box has an anti-flotation collar and a sealed and securable lid for order control and safety. The sampling container has inlet and outlet seals with 4” separation to allow uncontaminated sampling.
