Quick4 Equalizer 36 Chamber

The Quick4(r), Equalizer 36 Chamber can be placed in a 24″ trench. It is suitable for straight or curved systems. The patent-pending Contour Swivel Connection, which allows for turns of up to 10 degrees, left or right, is featured in the chamber. MultiPort, the end cap, allows for multiple piping options and eliminates all pipe fittings. The chamber’s length of 4′ allows for maximum installation flexibility. It can also be installed in a trench 24 inches wide. With its Contour Swivel Connection, the chamber has advanced contouring capabilities. MultiPort End Cap allows maximum flexibility in piping thanks to its six molded-in low and high inlets.

Installation of Inspection Ports

  1. Use a hole saw to drill the 4-inch opening in the top chamber.
  2. Place a piece of pipe cut to the right length in the chamber’s inspection port sleeves.
  3. Two screws are used to attach the pipe to the sleeve surrounding the inspection port.
  4. At the right height, attach a threaded cap/cleanout assembly to the protruding pipes
  5. If the grade of the inspection port is lower than the desired, a small valve cover box can be used.
  6. Level the area. To ensure a proper fit and easy installation, excavate an additional foot around the perimeter.
  7. Dig through any layer of soil that is not suitable, if necessary. Be sure to remove any debris from the walls. As per the designer’s plans, prepare the sub-grade soil for the chamber bed.
  8. If excavating has caused smearing, rake the sides and bottom. Use a transit, laser, or level to verify that the bed’s bottom is level. To prevent soil compaction, loss and subsequent reductions in soil infiltration capacity, minimize or avoid walking on the bed’s bottom.
  9. If pressure distribution is needed, refer to the Mound Systems section for the instructions on Pressure Pipe Design Options.

What are the best places to find local installation codes, system designs, and technical questions?

Local codes govern many installation options and requirements. When in question, check with the local health department for specifics and follow their code instructions. Infiltrator MicroLeaching sidewall louvers are designed to keep soil out; therefore filter fabric is not needed..When installing the chambers in sandy soils, mound, or fill systems the sand base should be compacted. This provides the chambers with a solid foundation and does not affect the infiltration rate.

What systems can Infiltrator Chambers be installed in?

Infiltrator chambers are suitable for almost all septic leach fields. Infiltrator chambers are able to be used wherever stone and pipe can fit. These include trench, bed and elevated mound installation. Infiltrator chambers offer superior treatment capabilities for pressure dosing and serial distribution.

What is the maximum size of the Leach Field that can be reduced when I install Infiltrator Chambers?

Each local health department determines the system size. Health departments usually approve sizing cuts of 25 to 50% when Infiltrator chambers have been specified. For details, check your local health codes.

Can chambers be installed under a driveway or paved surface?

Some codes prohibit the installation of septic leach fields under impervious surfaces, such as driveways. The reason is that the soil can be compressed by the pressure of the surface, which can cause a decrease in its ability to filter effluent (wastewater) from the soil. For the exact codes applicable to your area, check with your local health department.
