Installation Instructions
Installation instructions and additional components are included with the interceptor.
Read all instructions prior to installation. This interceptor is intended to be installed by a licensed plumber in conformance with all local codes. Install sampling port as close as possible to and downstream from interceptor being served
Provide at least 16″ clearance above unit for routine maintenance. Above Grade Installation Additional Support
To prevent connection failure or damage to fittings, ensure heavy inlet and outlet piping (such as cast iron or long runs) is properly supported or suspended during entire installation process.
Above grade installations must be supported by a platform or trapeze (not included) that contacts the entire footprint of the unit. Composite cover C24BC is recommended for use in above grade installations.
DO NOT USE CAST IRON COVERS IN ABOVE GRADE OR INDOOR INSTALLATIONS Use composite cover C24BC only for above grade installations ODOR ALERT!
Sampling port is not a sewer gas trap. All upstream fixtures must be trapped Below Grade Installation Slab Requirements
A concrete slab to finished grade with rebar is required when installing sampling port below grade.

1. Excavate Burial Pit Excavate hole at least 12″ larger than sampling port on all sides and 6″ deeper than port bottom. Lay a level bed of well-packed, crushed aggregate (approximately 3/4″ size rock or sand, with no fines) in the base of hole.

2. Connect Piping
   2a Install plain end fittings
   Screw plain end fittings (included) into bulkhead fittings using pipe thread sealant or tape approved for use with plastics. 2b Connect sampling port to drain lines Place unit into final position and set level. Mechanically couple inlet and outlet drainage lines to unit. Do not solvent weld. Ensure all upstream fixtures are trapped. Vent per local code.

3. Install Above Grade Support (by others)
   To prevent damage to drain line connections, SV24-O above grade installations must be supported by a structure (not included) built on-site. The support structure may be a platform or trapeze that contacts the entire footprint of the sampling port and is able to hold the weight of the unit.

4. Bring Covers Flush-to-Grade
   The SV24-O is ready for burial depth of 22″ from finished grade to bottom of unit (or 12-1/4″ to centerline of inlet).
   Deeper burials will require extending the Cover Adapter and possibly adding risers.
   Loosen the Cover Adapter Upper Band Clamp using 7/16″ Nut Driver Bit. Adjust Cover Adapter heights as needed. Maintain a minimum 2-1/2″ insertion depth. Tighten Upper Band Clamp to 5 -8 ft. lbs. of torque using 7/16″ Nut Driver Bit. If required, Cover Adapters may now be tilted up to 10º in any direction using gasket flexibility.

5. Backfill and Finished Grade Backfill evenly around tank using crushed aggregate (approximately 3/4″ size rock or sand with no fines)or flowable fill. Do not compact backfill around unit.
   5b Pour concrete slab to finished grade

Vehicular Traffic Areas:
Minimum 8″ thick concrete slab with rebar required. Thickness of concrete around covers to be determined by specifying engineer. If traffic loading is required the concrete slab dimensions shown are for guideline purposes only. Concrete to be 28 day compressive strength to 4,000 PSI. Use No. 4 rebar (ø 1/2″) grade 60 steel per ASTM A615: connected with tie wire. Rebar to be 2-1/2″ from edge of concrete and spaced in a 12″ grid with 4″ spacing around access openings.
Pedestrian Traffic or Greenspace Areas:
Minimum 4″ thick concrete slab with rebar required.
