Solve this little diy thing
 

Looking for suggestions.

I need to be able to push a button and dose a very small amount (about 1/4 oz) of liquid from a container, through a one way valve, into a tank, a distance of about three feet. If necessary the container can be above the tank for a gravity feed, but it would be better if that didn't have to be the case. The tank won't be pressurized.

What this is all about? My commercial dishwasher doesn't have the rinse aid pump and those parts cost several hundred dollars from Hobart. All the pump does is pull a dose of rinse aid from a gallon jug on the floor and pump it into the tank that holds the 190F rinse water, before the rinse cycle starts. Now, I don't need rinse aid except when washing wine glasses. So I just want to manually cause rinse aid to be added to the rinse water tank only when I'm washing glasses. I assume I can use the same fitting that the pump is normally attached to.

Anyone familiar with catalogs and happen to know the parts that can be put together to accomplish this at not very high a price?

Ideally, you want to pump this up into the dish washer? How about filling those big plastic detergent bottle you get from Costo with Rinse Aid? One press will get you a few drops if you hold it, it will release more.

Could you rig something up using a bottle with a pump? Think soap dispenser. One pump would dispense a roughly consistent amount. If you want bigger they make pumps that install into oil bottles that are used for filling things like differentials and boat outdrives, they have a hose attached that might be easy to hook up to a nipple on your dishwasher and could definitely pump a rinse aid upwards.

What about an enteral feeding bag? Fill it from the top and use a roller clamp to administer the rinse agent manually.

I think we have a case or 2 on the prop truck left over from Code Black. I can send them for cost of shipping.

I was going to say "how about a water softener and filter?" but then I read OPs first post again.

Hobart is pricey stuff.
Don't want to mess up seals/pump with the wrong chemicals or tweaks.

Were it me I'd just drink the wine from the bottle.

How about DIY'ing a freezer ice-maker solenoid with some tubing/plumbing and hook it up to a power source with a pushbutton to activate it?

Off that big river place for $14.21:

Peristaltic Liquid Pump. Either on a timer, or count revolutions with an arduino or raspberry pi/.

I think that is a good direction. A cheap peristaltic pump 12V, a wall wart, a timer switch, and a case. Figure out how many seconds to turn the switch to, for the desired dose, and write that on the case.

The other ideas could work but my wife is not going to like bags hanging around like I'm giving the dishwasher a transfusion. I'm already on thin ice with this d/w.

you can buy stenner pumps pretty cheap.

connect it to the liquid tank and time how long you have to press a button to dispense the necessary rinse agent.

So... You're going to have to stand around waiting for the rinse cycle and hit the pump at the right time?

Does the rinse aid have to be added at a certain time? If not, can't you simply add a little before the cycle starts? Then adding it would be as simple as adding detergent.

Fuggitabouit. Put 2-3 oz of white vinegar in the bottom of the tub before you run it. Thank me later.

I'll try adding rinse aid or vinegar at the start of the cycle. If I want to duplicate the normal machine operation, the rinse aid is supposed to be added during the rinse cycle. But maybe it doesn't matter. I'm also trying using less detergent as some of my spotting could be from too much detergent.

The cycle is only 180 seconds. During a large dinner party, I'll run the dishwasher 10 or more times. All the pots and pans and prep stuff gets run during the cooking, then the dishes and serving stuff, last I do the glassware. That's for, say, 15 people with 60 dishes, 50+ glasses, 75+ pieces of flatware, dozens of tea cups and saucers, a dozen serving platters, etc. My wife likes to set the kind of table where there are three different forks and four different glasses per person. For regular family meals, we don't use the dishwasher at all.

In my restaurant the Hobart was more or less a sanitizer, the "washing" was done by a powerful rinse sprayer, and not one of the "commercial kitchen" look residential ones. It used almost no detergent unless the salesman set the metering, and was more or less a 240 degree rinse.

How about some kind of gelatin packaging like Tide Pods?

Hahahahaha!!!

Thank you. I'll try less/no detergent. I fill one sink with hot soapy water, bus scraped dishes into that, when the sink is full I pass the dishes under the spray (just a residential one) plus a wipe with a brush if needed, and place dishes in the dishwasher rack.

Did you have a little undercounter Hobart like mine, or one of the big ones where you pull the hood down?
