Can OtO be run off of a rain barrel?

No. OtO requires pressurized water in order to operate.

If you are interested in using a rain barrel, you would need something to pump the water from the barrel into the OtO device. These types of pumps usually require a high amount of power and a 110v wall plug.

The current product design does not include a pump such as this, but is a common request and likely to hit our roadmap in the future.
