This is a long shot, but I'm running out of ideas.
I've recently set up a water tank to provide irrigation for our garden plants (blackberries, blueberries a few grapes). The water tank is about 400 feet from our pond. I put in a 1.5" pvc line from the pond edge to the (1500 gal) tank. We fill the tank and then let it gravity feed our drip system. The tank is about 3 feet higher than our garden, and water flows freely through the 3/4" pvc output side and through the drippers.
After all the work of trenching, gluing and covering, I was happy to see it all work. I got out a timer that attaches to a water faucet and lets you water when on a schedule. But I wasn't prepared for the fact that the timers apparently depend on having water pressure to operate. One I tried never opens, the other never closes.
I've poked around the web and one company makes one of these hose timer gadgets that will operate on 5 PSI, but I'm' probably working with more like 2-3. I'd have to raise the tank 6 feet or so to get 5 PSI, and given what 1500 gallons of water weighs, that's not really an option.
I'm wondering if all electric valves, such as the ones used in sprinlker systems, require pressure to work. I'm trying to find some way to water on a schedule, since I'm not there most of the time.
Anyone have any ideas?????
