Float/shutoff valve for standard 5 gallon bottle.

Are there any shutoff valves or does anyone know of any parts that would work with a standard 5 gallon drinking water bottle?

Toilet float kit would work. Most floats are mounted to the sidie wall horizontally. If you don't want to drill the container, you'll have to find one that fits in the top, and works vertically.

What are you trying to make?
I've seen theses before.

I'm retired from a water bottling business. I might be able to help.

I'm looking to fill the bottles from my RO to use in a coffee machine and multiple humidifiers. Right now I time 40 minutes to fill about 8 gallons into two bottles. I had a brain fart and let them go the other day and dumped a good amount of water onto the basement floor.

Normally there would be a pressure tank that takes in the ro and the ro shuts off when it's full. But the tanks are only around 2 gallons that comes with a RO unit.

But larger pressure tanks are available.

Something like this would give you lots of storage.

They make longer electric fuel/water sensors like this. Maybe you could drop one right in the opening, to switch on a solenoid valve or something once full.

Maybe you could put multiple overflow tubes going into each consecutive jug, so after one fills it starts filling the next one, then the next one.. Then when it gets to the last one a sensor could close off the solenoid valve.

You're probably wanting a mechanical float though right? I bet you could rig something up, where a long piece of PVC pipe with a cap on the ends could be dropped down in, and attached to a normal float that wouldn't otherwise fit through the filler necks of the jugs....

Or something like this. Not sure if it will drop into standard 5 gallon jug openings being 48mm wide (almost the same?), but the actual plastic valve part itself probably would. They sell just the valves too, the same parts like like the pics above but without the fancy SS shroud...

What I do is run RO to a larger tank. Used to use a cut off 45gal to about 30g with a plastic sheet covering the top. I now use a stainless 10gal olive oil container. Use just a float valve. Shuts ro off when full. Run a ball valve at the bottom with a short chunk of garden hose to fill buckets and what not. RO actually makes more water without a pressure tank causing back pressure. You’re going to have a hard time fitting something in the top of a 5G water bottle. Maybe a food grade plastic 5G bucket. Like mentioned most valves mount to the side. Drill a hole the hight you want and mount the float. Usually where the 1/4 hose is connected.

Solenoid...bloody brilliant!!!

This will be a perfect fit. I have numerous timers and old 12V power bricks. I can just chop the end off and crimp on some blade connectors.
It will also be very cost effective compared to those pressure tanks, I have a Y fitting on the end so I can fill 10 gallons for about $20.

I know the large tank float valve setup is easy, but I have the RO mounted on the wall in my laundy cubby and didn't want a large barrel in the way.

I might do something like that. Not that I've ever overfilled and run water over the basement floor...
Since this afternoon.
