wanted; out of box thinking, on gravity pres. irrigation

[del]

I have had an automatic irrigation system for several years. The problem is being a gravity pressure system the pressure varies a lot, and some days (getting to be several days a week) not enough pressure to shut the valves off.
Any ideas? Have considered a booster pump, but which one, cost, and not sure if I can legally install one have kept me from trying.

Can you pressurize your water storage tank?

I have no storage tank, just a pipe from the canal (30+ other houses also hooked to same pipe). Yakima has a irrigation system for watering lawns in town, that for the most part is gravity feed. When the system was installed during the depression auto sprinklers were not considered.

The only thing I can think of is an electric solenoid valve on a timer that would shut the entire system down???

That's what I have on mine and it works well.

I tapped into the old well (SHHhh) and have a demand pump...still a flowing source.

But its kind of like lowering the river instead of raising the bridge in your case.

Adding power to an system that doesn't need power.

My problem with that idea is 1. all auto valves I have seen require more pressure to turn off than I have. 2. when the system turns on, if there is not enough pressure on one valve, random other ones will come on to. If I could just find a valve that worked with lower pressure, I would buy 12.

An electric solenoid valve will work with No pressure...Not even any water.

You have 1 water line going into you property. Interrupt that line, install a Solenoid valve.

Run wires from the solenoid into the house with a plug on the end. (make sure you get a 110V solenoid)

Buy a wall timer, set it for when you want it to go on and off. Plug it into the wall and the Solenoid plug into that.

The valve is like a light switch...power to it, its open. Power off...its closed. Or visa versa.

I'm on my slow computer now so I can't look up 110V water Solenoid's There about $20...a $10 timer and the wire and your done.

If your having problems with some valves, put a solenoid on them too.

I have a similar situation. I don't have enough pressure to run all my sprinklers at once. I have 3 zones and run them on timers in sequence through the night.

But again....Its like lowering the river instead of raising the Bridge.
