Which device provides automatic drainage of collected debris from filter housings?

• A. Filter Controls
• B. Wire
• C. Automatic Drains
• D. Enclosures

Answer: (C)

Automatic drainage devices purge the sediment and debris that collect at the bottom of filter housings without manual intervention, keeping the filtration path clear and maintaining proper flow. They are integrated into the filter system and typically open during backwash or on a set schedule to release the accumulated debris, preventing buildup that can reduce efficiency.

The other options don't fit because filter controls manage when the filter cycles or backwashes, not the automatic removal of debris; wires are simply conductors or components, not a drainage device; enclosures are protective housings, not mechanisms for draining debris.
