Sizing a pump for Drip Irrigation - Can I use a 1.5 HP, 2" outlet
Sizing a pump for Drip Irrigation - Can I use a 1.5 HP, 2" outlet to pump RO treated water to my plants?
I have two 330 gallon tanks, filling with RO treated water. Each has a 2" outlet. I want to set up an automatic drip irrigation system for 200 potted plants in 15-gallon containers.
The rise would be at least 2 feet. I figure that I would set leads from the tanks into a pump which could then push the water through drip irrigation tubing up to the plants. I am very cautious and afraid to get started. I assume each drip emitter will be 1-4gph, and I would like to water for less than an hour.
So, I have a used pool pump, 1.5 HP with 2" inlet/outlet. Can I just hook this up to the tanks and turn it on? Would downsizing the outlet to a 1" drip line cause the water pressure to blow out? I can water the plants in sections if necessary.
My alternate option would be to use a 0.5HP 1" pump.
