My wife would like to use our dishwasher more often but sometimes we get a little overflow spilling out of the air gap valve. It would pose a problem but our sink is a stainless steel lip mount and the overflow winds up on the counter top. Not much but enough to warrant an occasional sponge clean-up. I've checked the line and it is clean, in fact new. And yes, the knock-out on the disposal has been removed. Is there an Air-gap valve that has a spout to direct water to the sink basin rather than the common slot found on the chrome cover?
Thank you for any and all advice,
