Water Quick Disconnect

There isn't a space in my kitchen to put a built in dishwasher, so I'm going to build a cabinet and make a portable dishwasher. I've already solved the counterbalance and drain water issues, now all I need to figure out is the hot water feed line. I'd like to make a system that uses a quick disconnect so that my wife can just plug it in with no hassle. Would a standard air line disconnect work with water or is there something more suited for liquids? Thanks!

There are quick lock type of fittings for high pressure hydraulic lines on heavy equipment, I am sure you can get some to handle 90 psi water pressure.

I know that most air fittings do not like water (internal parts corrode easy), so you may need to contact a local industrial hose company to get some hoses/fittings made up.
Lines similar to the type used on soda fountains is a possibility.

Go to a local hardware store and explain your problem. I believe they should have the "quick disconnect" coupling that just slips over the kitchen sink faucet discharge or a suitable alternative.

If that doesn't work, go to an appliance store that sells portable dishwashers and ask them how you're supposed to connect to the water supply line, since most such washers are rolled into and out of the kitchen as needed. They'll know about how you quick connect it.

Why reinvent the wheel? Get a portable dishwasher. They piggyback off your sink when you use them, then you unhook them and roll them out of the way. They usually have some sort of top on them that allows them to be used as an additional prep area, too.

I agree with jroehl, just get a portable dishwasher..

If you insist on doing it yourself then get the proper inlet tube..

If you don't do it right you may end up flooding your kitchen..

Here is a link to a Maytag inlet tube..

They do make water quick connects. Most of your garden hose reels use them. A portable dishwasher would be your best bet with the least potential for problems.

Problem with the portable washers is that they usually cost twice as much because you are paying for the portable cabinet. If I make a portable cabinet for a built in style dishwasher, I can take the washer and turn it back into a built in, under the counter style when I move to a new place that has the room for it. I've looked into the faucet connectors and I can use that as a last resort if I can't come up with a feasible quick disconnect system. Thanks for the advice so far!

All the quick connect fittings I've seen for water use are junk. They are made for garden hoses and leak. The ones used for hydrolic use would also corrode like an air line system would corrode (especially if you have municipal water since they use chlorine) I would check first with a retailer that sells dishwashers and see what type of connections they have. Most portable units are made to be installed permanent as well, so there has to be something to use. If not, then the next thing I would reccomend is go to Home Depot or Lowes and make your own out of different fittings. You can maybe gat something together that will connect to the threads for the aireator on the faucet. If not, then make on to connect to a hose bib and put a bib under your sink somewhere.
