BASIN & PITS

Drawings show standard arrangements of simplex and duplex VSP units. Square steel covers are for concrete pits and are usually furnished with grouting frames. Round steel covers are for cast iron, steel and fiberglass basins. When round covers are for concrete pits, they are usually furnished with grouting frames. Covers have a corrosion resistant coating. Non-standard shapes and arrangements are available.

Type PF-1 furnished as standard for square and rectangular pits. Permits frame and cover to be installed flush with finished floor. Has bar support for cover.

Type PF-2 construction same as PF-1 except with angle iron support for cover.

Type PF-3 furnished as standard for round pits. Frame supports cover and should be recessed into concrete so that cover is flush with finished floor.

Type PF-4 construction same as PF-3 except with filler strip. Frames and covers are treated with corrosion resistant coating, and are available in non-standard shapes and sizes, sectional construction, and galvanized or checkered steel.

DIMENSIONS
Dimensions are subject to change and should not be used for construction purposes unless certified. All dimensions are in inches unless otherwise noted.

SIMPLEX AND DUPLEX UNITS
While the dimension drawing on this page shows a duplex unit in a basin, the data on the drawing applies to simplex and duplex units.

INLETS
Basins can be furnished with any number of inlets, of the styles shown on this page, in sizes 2" thru 8". The inlet depth is determined by job conditions such as distance from farthest fixture and pipe pitch. Indicate size, style and depth of inlet in the boxes provided on the drawing, when releasing the basin for fabrication. Unless otherwise requested, the inlet centerline is directly below the centerline of the manhole.

COVERS
All basin covers are steel. Covers for cast iron and fiberglass basins are bolted onto the top flange of the basin. Covers for steel basins are welded onto the basin shell and, therefore, there is no top flange. Basin covers have required openings for pumps and controls plus a vent connection and a manhole (with a cast iron manhole cover).

The standard vent connection for a sump pit or basin cover is a 3" screwed connection. If local code requires a 4" vent connection, it must be so specified when the unit is ordered.

Covers are furnished with bolts and gasketing for gastite field assembly on the basin. Pumps are furnished with bolts and gasketing for gastite field assembly on the cover.

SECTIONAL BASINS
Standard steel and fiberglass basins are built in one section. Mufti-section basins are furnished only when specified.

Standard cast iron basins are built in one, two, three or more sections, depending on the basin depth. The intermediate flanges of multi-section basins have the same outside diameter and bolt hole dimensions as the top flange on which the cover is mounted. Bolts and gasketing are furnished for field assembly of the sections.

SQUARE BASINS
Square and rectangular basins are available in steel construction only. Cast iron and fiberglass basins are not available in these shapes.
