I don't get the problem here. If it's a sealed system, a pressure switch should be enough to deal with a pressure tank, up to a certain flow.
For a heavy-duty application like yours, use a brass valve with the 110 volt solenoid, though I'm not sure that IS the application.
The storage tank is not sealed.
Use a float valve (auto-fill for water features). When the level drops, the float valve will open and let water in, when it's full, the valve closes. No electricity required, works on water and air.
Here's a whole bunch of options- http://www.grainger.com/Grainger/float-valves/valves/plumbing/ecatalog/N-ac7
I've never heard of a sealed storage tank/cistern. Is Boots back on the stuff?
So that makes me wonder about the "flow chart" you provided.
One more time, is this a reclaimed water system? Or is every drop of irrigation water to come from the well?
Not a well man but can a second pump be installed in the well?
How would you set it up?
Here is the whole gig... which I did not want to get into to confuse everything.
Origonally this well was meant to feed one house. Now this well is supplying multiple houses and a irrigation system. The approx 15 gpm is not cutting it from the well. The well is very deep, and is not in danger of going dry. The pump is 280' deep and is estimated to be in at least 80-90 ft. of water.
There will be two side by side storage tanks, one for drinking and one for irrigation. This is why I cannot use a simple float shut off because then the other tank might not get filled. These two tanks will be set up about 50' from the pressure operated well pump.
I have a 200amp service about 20' away so the power options are vertually limitless in this situation.
This is how I will set it up:
- Well to 5000gal and 2500gal storage tanks, with a flow reduction to the irrigation tank so that the drinking supply will be able to refill faster.
- Irrigation storage==>Ball Valve (to hold pressure)==>Pump==>Pressure Switch==>Pressure Tank==> Irrigation System
The irrigation tank will not be pressurized as an added measure to insure drinking water quality. That way there will be an air gap in the tank.
This is where I remind everyone that I am dyslexic... so ignore spelling.
Every bit is coming from the well. There will be a ball valve installed between the storage tank and the pump to keep the pressure on the pressure tank.
Advanced flow chart for boots-
Well Pump==>Pressure Switch (PS)==>Pressure Tank (PT)==> Irrigation Storage Tank==>Ball Valve[to hold psi]==>2hp pump==>PS==>PT==>Irrigation system
My concern is between the wells pressure tank and the irrigation storage. I need something to shut it off using well pump pressure switch.
I hate to say it but I may need to un block Kiril for his input...
