(DEPRECATED) Dewitt Dew Right Tree Watering Donut Bag compatible Garden Hose(GHT) Adapters

Deprecated - see this revised print. 

Garden hose thread adapters that are compatible with Dew Right Tree Watering Donut Bag. 

Watering donuts are a great tool for any landscaper or home owner looking to establish small trees without irrigation. The slow release of 15 gallons beats filling buckets that get stolen. They are also superior in ensuring that trees do not get mold or rot like trunk watering bags. They are also easy to install, fill and remove when done. 

The big downside to them is that, if you have more than a bag or two, you quickly get tired having to position the hose in the filling hole and keep the bag raised while it fills. Since my mobile watering rig takes roughly 3 1/2 minutes to pump 15 gallons, my knees are done after two bags. That's where these adapters come in. 

These adapters are designed to fit to the proprietary threads on the closure cap of the Dew Right bags and provide either standard male or female garden hose connections. 

The female adapter also features a swivel connector so now need to twist things. 

Pair these with a brass hose quick disconnect set and you have a quick and easy method to watering trees with no fussing or squatting. Simply get your hose to the bag, remove the QD plug, attach and start filling. 

While a bit more expensive, I prefer using a double female garden hose coupler with a male QD on the filling side while keeping a female quick disconnect at each bag. That way I can plug each coupler after filling but even just having a basic swivel connector with a plug like this will work.  

I've tested this print for over a month now and have only had an issue once or twice with the adapter slipping on the bag. I'll release a v2 once I can do some more testing to ensure a better connection. 

Meanwhile, the trees are happy and putting on growth. 

Suggestions

I highly recommend printing garden hose plug or quick disconnect plug whichever route you go - this will ensure bugs and other debris can't enter the bag after you finish filling. 

A gasket on the Dewitt bag side is not really necessary as the bag has an internal blocking flap but installing one shouldn't impact things. Even a small leak isn't the end of the world as it'll stop once the interior pressure of the bag decreases. 

If you have a large # of bags to fill, I highly recommend getting a flow meter to know how long it typically takes to fill the bag with 15 gallons.

A hose-end shut off valve is also a necessity. 


Printing

Print at a higher resolution(0.16mm) - no supports needed. 

Orient with garden hose side facing down. 

I suggest 4 walls for maximum durability.

You must use UV resistant filament such as PETG.
