Hello all,
I have installed a rainwater harvesting system that feeds an underground storage tank. It is all powered and controlled by a 195 watt solar system. The tank is directly below the ground surface. It acts as an overflow for an above ground cistern. We are pumping the water out of the underground storage to a micro jet system with a 12v Shurflo 2088(45psi, 3.5gpm). We are having trouble keeping the pressure up enough to power about 15 heads spread out over about 100 feet of line. I am looking for a bit of help with the design of this system. The question I have is if anyone knows of a 12v valve and solenoid. We have considered splitting the load going out to the heads into two zones powered by a 12v irrigation timer. All I can find in the retail market is 24v. Can I use the 24v valve and a transformer? I would rather keep the power drain to a minimum.

Thanks,
John

P.S. I am in Florida, a bit different conditions and less info.

Do a google search. They are all over the net. Normally open/normally closed. They will only draw power when energized doing the opposite.

You can search the water pumping thread with my posts about freeze proof off grid water system where I may have referenced a source.

Or, use a 5.9GPM shurflo pump "smart sensor" 65PSI should help!
