snap on hose connector for 5 gallon water bottles

[bkobernuss]

Total plumbing noob here.
Here in the DR we drink exclusively from a supply of 5 gallon plastic water bottles that come by truck.
I am setting up a filtration system to further refine this water.
I need to connect a bit of small hose on the intake of my filtration system to the mouth of these 5 gallon bottles (pretty sure the size of the mouth of these bottles are pretty standardized worldwide). Ideally the connection would be some kind of snap on device that I can just lock on to a new bottle when I need to switch them out.
The idea is this will be gravity fed - I will turn the bottle upside down in a holder placed above the filtration system.
My filtration system has a valve on the intake, so all i need is a simple snap on connector at the end of a hose.

Tried some google search for such a product to no avail yet - hoping someone either knows a good product or has a good DIY solution.

Post some pics of everything, including the mouth of one of your water bottles.

With a tape measure across it, or post the exact inside and outside dimensions of the opening.

I make wine in five gallon bottles, and I use big rubber stoppers.
Not sure if they would stay in upside down.

Option B is to drill a hole in the lower side of a bottle, and add a male hose adapter.
A bulkhead connector, like you would use for a rain barrel.

You would have to refill this with a funnel for each new five gallon batch, but it would work.

Really just something that can snap on to the mouth of one of these bottles - so long as the other end of it has some kind of fitting i can attach to some hose, that part should be pretty easy to make work, its just attachment to the bottle for a sealed, upside down gravity fed situation that I'm hoping to figure out

Post a side pic of the bottle mouth.

And does yours have threads on it?

 

[bkobernuss]

there arent any threads on the bottles they use here, inside or out. just these little lip areas

A fitting like this would slip over the mouth and tighten up easily.

Then you can take it to a hardware store to buy fittings to adapt to a male hose thread, or buy them online.

Brilliant! Thats, basically exactly what I was picturing.

Have a great day, Jeff, you did me a good one.

The inside diameter of that big end is 2 and 25/64 of an inch, which is just a tad bigger than your bottle mouth.

If the only fittings you can find to fit into the small end are threaded, just wrap the threads in several tight layers of teflon tape, and then the rubber with a clamp will seal over them fine.

Many companies make that same exact type of rubber reducing coupling.

Two or three drops of chlorine bleach from an eye dropper into your filtration tank would be additional safety insurance.

It off-gasses pretty quickly anyway, unless your filtered storage is air tight.
