Buying Guide
Key purchase considerations help ensure you select the best air gap for your kitchen setup:
- Finish and style: Choose a finish that matches your faucet, sink hardware, and overall kitchen design (stainless, satin nickel, brushed nickel, brushed gold, or champagne bronze).
- Material quality: Look for solid brass components for durability, with a robust ABS body for cost effectiveness and resistance to corrosion.
- Size and compatibility: Verify inlet sizes (commonly 5/8 inch or 7/8 inch) and pre-drilled hole requirements. Ensure the unit fits your sink deck and aligns with your dishwasher’s outlet.
- Code compliance: Confirm that the air gap meets local plumbing codes; most regions require an air gap for dishwashers to prevent backflow.
- Maintenance: Consider ease of cleaning and the likelihood of water spots or tarnish on the finish. Finishes like brushed nickel and champagne bronze may show less wear in busy homes.
- Warranty and support: A solid warranty and reputable customer service add value and confidence in installation and long-term use.
In selecting a dishwasher air gap, weigh aesthetics against durability and ease of installation. The best choice balances a durable, code-compliant design with a finish that harmonizes with your kitchen’s fixtures and style.
