Solve cross-draining problems with your Doule-Dishdrawer permanently!
Are you experiencing cross-draining problems with your older Fisher Paykel double dish drawer? Have you had a succession of technicians and service companies try to solve this problem, only to have it return again?
There is a reason this is happening to you and there is a way to fix it FOREVER.
In most cases, this problem can be traced to an improper installation. Fisher Paykel double-dishdrawers are in effect TWO dishwashers with two seperate drain hoses. Often times they are installed with an "air gap" which is required by many municipalities for code compliance. Installers who are used to installing "single" dishwashers often install a "single air gap" with a Y-adapter that connects both drawers to a single air gap, and to be fair, this is shown in the install instructions for the product. However it will usually not work for very long. The reason being, there is a small neoprene "check valve" in the base of the pump on both drawers. It is designed to keep the water from the last drain cycle from running back into the machine once the cycle stops. It was never designed to prevent the cross-drain condition. Over time the pressure from the water that wants to come from the other drawer will weaken that flap, causing it to "leak" and the result is when one drawer is run, the dirty water from one drawer drains partly into the other drawer. (YUCK!) Most techs will replace the flap, thinking they have solved the problem, and for awhile, yes, it will.
But this can get kind of expensive having to call for repairs every year or so.
The proper and permanent fix for this situation if to install a DUAL AIR GAP which can be purchased from Fisher Paykel parts: http://fisherpaykelparts.net/index.php?categoryid=1&productid=7
This device is totally "co-axial" in design and will not allow water from one drawer to get into the other. It also is "kosher" in that some Jewish families have a "meat" and "dairy" dishwasher and the two can never be mixed. If there is cross-draining going on, that is "not Kosher!" (pun yes, reality also!) This part will insure no cross-contamination.
These dual air gaps come with everything you need to replace a single air gap, and fit in the same hole. You can even transfer most decorative style covers that the customer may have on the single air gap (such as Bisque/Brushed Aluminum/Brass etc.) The feedback we have gotten from our own customers after instaling one of these is extremely positive, some going so far as to say it is like they have a new appliance, as it is now cleaning better than ever and there is no longer an objectionable odor coming from the drawer.
This is an excellent and PERMANENT code-compliant solution for cross-draining on older Fisher Paykel Dishdrawers. Try it. You'll like it!

Appreciate your response and while im sure it works, drilling more swiss cheese into a custom granite countertop isn't an acceptable answer. Fact is Fisher Paykel provided the instructions originally and they were followed by whover installed my machine. FP even provided the Y piece that was originally used in the installation. The rubber flaps are supposed to keep the water from flowing back into the the dishwasher and do meet most code requirements as an integrated anti backflow device- if they weren't designed as such then FP should have suggested the use of an air gap in the installation instructions rather than touting it as a feature. The problem isn't the Y connector or the lack of an air-gap, the problem is it is the poorly designed piece of art that FP engineers sent off to manufacturing. For a $1000+ dishwasher (7 or 8 years ago) there are just too many poorly thought out aspects to this machine's design, and the fact that FP is expecting people who bought this machine to keep spending $100 here and $200 there to replace these parts after a few years is insulting. What you have provided is a reasonable work around to an engineering oversight - thank you....
In fairness, what FP should have done was provide a true air gap or a real check valve for each line internal to the machine and a single drain line out, rather than having two separate drain lines and leaving it to the installer to deal with.
As a suggestion, for those that don't want to make more swiss cheese, get two inline air gaps (one for each drain line) and run them to the rubber Y and then into the disposal. That will serve the same function and prevent the waste from one machine flowing back into the other.... No swiss cheese, no major modifications, nothing showing, and less expensive....
