Pick by drain type and the pipe/receptor size you're fitting:
| Cylinder strainer | Drops into a floor sink to catch solids; sized by diameter and height. |
| Floor drain strainer | Flat grate/strainer over a floor drain in wet areas. |
| Floor sink | Recessed receptor that receives indirect (air-gapped) equipment drains. |
Kitchen equipment drains to floor sinks/drains through an air gap (indirect waste), never a direct connection — that prevents sewage backflow into food-contact equipment. Strainers keep debris out of the drain line and are a routine inspection point.

Code requires an air gap (indirect waste) between food equipment and the sewer so a backup can't siphon into the equipment. The floor sink is the receptor that provides it.
Catches food solids and debris before they enter the drain line, preventing clogs and keeping the area sanitary — a basic inspection expectation in wet zones.
