Review on 🔝 WirthCo 32410 Funnel King - 1" Thread Polyethylene Drum Funnel: 3 Quart Capacity, 1” Thread by Rich Schobinger

The funnels are a 5 star funnel used to collect water flowing down the sprinkler string into a 55 gallon plastic drum. According to the product description, this is a 3 star description. Which 2 inch thread does it have? I think it has an NPS (National Pipe Straight) thread. But many plastic barrels sold for rain barrels have 2" support threads, so the adapter on this funnel actually goes through the cork to the rain barrel without snapping in. That doesn't matter, because you don't necessarily need waterproof yarn to catch the rain. This adapter is likely screwed into a thread on a metal barrel. Revain sells an adapter that fits a 2" support thread and adapts to a 3/4" pipe thread, which I also used. See https://www.amazon.com/Knock-Buttress-Coarse-Thread-Gasket/dp/B00VVWJ0EI
