What is an air gap in Bosch dishwashers?
An air gap is a plumbing device designed to prevent backflow contamination in water systems. In Bosch dishwashers, the air gap serves as a physical barrier between the dishwasher’s drain and the household plumbing. It ensures that dirty water cannot flow back into the dishwasher, thereby protecting the clean water supply.
Typically installed on the countertop or sink, the air gap features a small cylindrical shape with an inlet and outlet. When the dishwasher drains, water flows out of the unit and into the air gap; if there were a site of backflow, the air gap would allow the water to spill over rather than siphoning back into the dishwasher.
Why is an air gap necessary for Bosch dishwashers?
The air gap is essential to prevent potential contamination of clean water used for washing dishes. Dishwashers often discharge dirty water, which may contain food particles, grease, and detergents. An air gap acts as a safeguard, ensuring that this contaminated water doesn’t re-enter the dishwasher or the clean water line, which can lead to health risks.
Additionally, many local building codes require an air gap to be installed for dishwashers. Failing to comply with these regulations can lead to legal issues and potential fines. Invalidating your warranty could also lead to expensive repairs if there’s a problem related to drain issues.
How do I install an air gap in my Bosch dishwasher?
Installing an air gap is usually a straightforward process, but it is essential to follow the manufacturer’s guidelines closely. First, you’ll need to choose a suitable location, typically on the sink or countertop. You’ll need to drill a hole if one is not pre-made, ensuring it is the right size for your air gap model.
Next, connect the air gap to the dishwasher drain hose and the kitchen sink drain. Use hose clamps to secure these connections tightly. Once installed, run a test cycle to check for any leaks and ensure the proper functioning of the air gap before finalizing your installation.
