Wow
Midman,
U have a nice and clear diagram. Thanks alot. Just to ask a few question:
1) Does ur main tank ever have water evaporate? if yes, will the water level goes below the cup overflow level and wat will happen, have u check b4?
2) So far have u tried with power cut off for more than few hours to check whether it will restart once power resume?
Bro, well done. really impress me.
