B. The inlet to the Infiltrator chamber shall be in the uppermost portion of the specially prepared inlet
panel ("end cap"). For dosed systems receiving effluent from a pump or siphon, manufacturer's
installation procedures shall be followed, including provisions to dissipate inflow rate so as to
minimize soil scouring and modifications that enable the presence and effectiveness of these
provisions to be field-verified.
C. The Quick4 Plus All-in-One 8 Endcap may be used as an accessory with the Quick4 Plus Standard
LP chamber to decrease the turning radius of a chamber line, as a drop-box in serial distribution,
and for mid-line distribution pipe entry and exit. The number of chambers in the chamber rows
extending in opposite directions from the Quick4 Plus All-in-One 8 Endcap do not need to be
equal.
D. Backfill shall be placed between the trench and chamber sidewall to a minimum compacted
(carefully walked in) height that is equal to the top of the chamber louvers. Chamber systems can
be installed utilizing native soil backfill (Group I, 11, III, or IV). Backfill shall be free of trash or
debris. The area adjacent to louvers shall be free of large (8"or greater) clods that do not break
apart during the walk in procedure. The latest version of the manufacturer's installation procedure
shall be followed.
E. The Quick4 Plus Standard LP chamber model may be installed with a minimum compacted cover
of 6 inches when the following conditions are met:
1. The person installing or constructing the system is certified (documented) by Infiltrator
Systems, Inc. as specially trained and qualified to install the Quick4 Plus Standard LP
chamber units with a minimum soil cover of 6 inches;
2. The person installing the Quick4 Plus Standard LP chamber system shall produce certification
documentation upon the request by the State or local health department.
3. When installing the Quick4 Plus Standard LP chambers the installer shall carefully follow the
manufacturer's installation guideline for shallow placement.
4. In Group I soils, with only 6 inches of cover, tracked equipment shall be used during Backfill
as specified by the manufacturer's installation procedures.

Vehicular traffic or construction equipment may traverse the chamber system only during system
installation. The load must be bridged over the trench so as not to disturb the chambers. The load
may be bridged with a minimum of six inches of compacted soil cover over shallow chamber
models and a minimum of 12 inches of compacted soil cover over other Infiltrator chamber
models.
F. Individual chamber trenches shall be constructed with ± t/2 inch of trench levelness from side-to-
side and shall follow the contour of the ground surface elevation (uniform depth). Trenches shall
be constructed with continuous interlocking chambers, without any dams, stepdowns or other
water stops, with a plus or minus 1-inch tolerance of trench levelness for any linear contoured
segment.
G. Infiltrator systems installed on a sloping site may use distribution devices or stepdowns as
described in 15A NCAC 18A .19550) and (1) when it is necessary to change level nitrification line
segments from upper to lower elevations. For the Quick4 Plus Standard LP chamber, the Quick4
Plus All-In-One 8 Endcap and Quick4 Plus Periscope pipe appurtenances may be used as a
stepdown by making the cross-over out of one of its pre-marked 3.3- or 9.0-inch-high ports. From
the end cap, effluent is conveyed through a solid pipe segment installed on a positive downhill
grade down to the next lower trench in series. For the Quick4 Plus Standard LP chamber, the pre-
marked port on the top of the Quick4 Plus All-In-One 8 Endcap may be used to receive effluent
from an upper trench by a cross-over pipe. Infiltrator's MultiPort Invert Adapter may also be used
to change elevation between nitrification lines for the Quick4 model chambers. Stepdown
installation details shall be in accordance with Infiltrator Systems North Carolina Design and
Installation Manual.
H. After installation of chambers in trench or bed configuration, a filter fabric barrier shall be
installed to cover the chambers (except Quick4 models) if chambers are installed in uncompacted,
fine or very fine uniform sand and at least one of the following conditions are present.
1. Installations are left uncovered and subject to a major rain event.
2. Systems are subject to not being sodded (or stabilized) in a timely manner after final cover-up
has occurred.
3. The drainfield is not protected from surface drainage.
The filter fabric shall be non-woven, weight 0.35 oz./s.y. to 1 oz./s.y., have apparent opening size
(AOS) 20-30 U.S. Sieve (ASTM D-4571), or alternate with equal or better performance
characteristics. An alternate fabric shall be approved in writing by the manufacturer on a case-by-
case basis.
1. Manufacturer's installation instructions for the applicable Infiltrator system used in septic tank
systems shall be followed except as required herein or 15A NCAC 18A .1900 et.seq.
J. All Infiltrator chamber systems shall be installed by a contractor or installer appropriately certified
in writing by the manufacturer.
K. The Quick4 Plus Standard LP chamber system shall be installed only with the Infiltrator Quick4
Plus All-in-One 8 Endcap or Quick4 Plus 8 Endcap options at the ends of each chamber row.
