During the winter months, many clients leave the state of Maine. Their piano is left in Maine, which means there’s nobody to fill the Dampp-Chaser! This is a solution.
My best estimate is that this system can supply a Dampp-Chaser with sufficient water for three months during the winter, or perhaps longer. Normally, they have to be filled once a week!
There is no pump or water pressure: The two containers are self-leveling using nothing but physics. This means that, in effect, the interior tank has nearly the entire capacity of the external tank. The lack of electronic components remediates risk of severe failures. The external tank I use is the Barker 10-gallon tote.
Although not necessary for operation, an Arduino micro-controller is installed to monitor the water level and send updates using cellular data. This gives us confidence everything is working as it should, even during long absences. This is in development, although the source code I’m currently using is below. At present, I’m using the Botletics SIM7000 shield and an Arduino Uno Rev3. I connect using Telnyx.
