Water transfer during rain
話題:
智能庭院
Assumption is that rain events need to prevent / skip watering.
I have one requirement that is the opposite where if it has rained more than 5mm, i want to use my watering system to pump water for about 15 minutes from my 100,000 litre water tank to a 12,000 litre holding tank that I use for gravity fed gardens.
Is there a way?
