Air Gaps
Air gaps are required by many plumbing codes (UPC - Uniform Plumbing Code is one) for dishwashers and for water softeners. We offer dishwasher air gaps in a large selection of finishes to help you match your kitchen sink and/or faucet. Air gaps have no moving parts and use the (free) atmosphere to protect from the reversal of contaminants. We believe that no matter what the local code dictates, every dishwasher discharge, in order to protect your family's health, must go into an airgap before discharging into a food/garbage disposer or drain.

Frequently Asked Questions
Q. "Why do I need an air gap?"
A. Air gaps are required by most plumbing codes for dishwashers and for water softeners. They are needed to prevent any possible cross-connection between your potable water system and your sewage system.
Without an air gap, there is always a chance (however slim) of siphoning contaminants from your sewage system into your drinking water system.
Q. "My airgap on my sink keeps spitting water every time that I run our dishwasher. What is wrong?"
A. Quality made air gaps are pretty basic products that rarely go "bad". If you purchased your airgap from us you can rest assured that it is a quality airgap. IF your air gap didn't spit in the past then
try running your garbage disposer for a few minutes. Basically the way your dishwasher airgap works is that water is pumped through the smaller side of the airgap (5/8") into the airgap and then gravity takes it to your sink (or disposer)
with larger hose (7/8"). The larger size has an area of about twice as large and with gravity there normally isn't any problem. If the 7/8" hose is sagging or there is grease build up or a partial stoppage or blockage in your sink/disposer
the airgap can "spit." After inspecting under the sink to make sure the 7/8" hose isn't kinked or going uphill at all (it has to go smoothly downhill all the way) then disconnect the 7/8" hose at the sink/disposer and point it into
a large bucket. Then run the dishwasher and see if the airgap still spits. If it does then you know you need a new airgap and if it doesn't then you know the "problem" is after the hose.
Q. "What are the sizes on the inlet and outlet of the dishwasher air gaps?"
A. Standard 5/8" i.d. (requires 5/8" inside diameter hose) for the inlet and 7/8" i.d. hose for the outlet.
