AquaStar 20-Inch Open Circle Drain and One-Port Sump, Medium Gray | OCD117

One 20-inch nominal Open Circle PVC sump body, one center logo cap, outer and inner disposable plaster shields, two 10-32 × ¾-inch flat-head Phillips screws in 316 stainless steel and one 2-inch NPT plug. Pool finish material, hydrostatic valve and service tools are separate.

OCD is the Open Circle design shown in the second image. Its current parts drawing has the sump body and center cap with two screws; it does not list the separate slotted perimeter cover used by FC. PC Perfect Circle is a different four-port assembly with vented baffles. These are distinct configurations and their flow ratings and installation documents are not interchangeable.

The 2026 catalog identifies one threaded bottom port with 2-inch socket × 2½-inch spigot × 2-inch NPT. Match the actual pipe and port arrangement to the complete OCD drawing and manufacturer instructions.

Yes. AquaStar identifies the Open Circle design for concrete pool and spa installations. The disposable plaster shield helps keep debris out of the sump and supports its shape during pool finishing. Use OCD-specific installation requirements for the actual pool.

The manufacturer describes the circular design as filled with plaster or pebble to blend with the pool interior and identifies a perimeter waterstop to help protect against leaks. The finish material is not included. A qualified installer must follow the manufacturer and pool-finish requirements without obstructing the required opening or access.

The current 2026 AquaStar catalog identifies OCD as an unblockable configuration, certified to NSF/ANSI/CAN 50 and ANSI/APSP/ICC-16 2017. The complete assembly, actual product markings, certified flow configuration and full installation requirements must all be verified; the catalog statement does not approve an arbitrary installation or modified assembly.

Obtain the current OCD-specific certified flow specifications and installation instructions from AquaStar before selecting or installing this product. The exact pipe size, geometry and operating conditions must match the approved configuration. Do not use the FC Full Circle or PC Perfect Circle flow table as a substitute for the OCD model.

Use AquaStar’s manufacturer flow and product support and request the current OCD-specific instructions, flow table and certificate. Match the actual product markings and manufacturing generation. The 2026 catalog’s Open Circle parts and dimension drawing is supplied as the second image.

No. The current catalog shows HVCxxx as an optional self-contained hydrostatic valve and separately lists OCDHVxxx as a combination drain package with hydrostatic valve and collector tube. Those are separate part numbers. This standard OCDxxx listing includes the components stated above.

The current catalog separately identifies OCD23109 plaster shields and FC08Kxxx center logo cap with screws. FC16102 is the optional T-wrench for the relevant 2-inch plug applications. Confirm the exact existing assembly and approved replacement components before ordering. These separate parts and tools are not included beyond the components listed for the standard assembly.

The 2026 catalog instructs replacement of the round center cap every five years. Replace damaged or insecure components and follow the complete model-specific inspection, maintenance and other component service-life requirements from AquaStar. A replacement interval for the complete Open Circle sump is not inferred from another Circle model.

This listing supplies one complete OCD assembly. The current catalog identifies one assembly per case. The separate plaster-shield and cap-kit case quantities do not change this listing’s quantity.

AquaStar’s 2026 catalog states a general one-year limited warranty from original installation for defects in materials and workmanship, subject to the complete terms and exclusions. Color fading, improper installation, poor water chemistry and other listed causes are excluded; non-approved components may void coverage. Repair or replacement is at AquaStar’s option. Read the manufacturer’s catalog limited warranty, printed page 238. A drain cover’s required replacement interval is a separate matter.
