    Table talk in Umbria on water conservation from the roof, we are being told causes calcification of the irrigation tubes and blockage of the pores. Has anyone else met this and if so how do you combat it? It is supposedly the guano on the roof that causes the calcification. Someone suggested 2 eels in the tanks takes care of everything! Any comments?

    Sounds a bit weird! Guano I think (from birds at least) should be a bit acidic if anything. Maybe ths could dissolve calcium from the roof (if you had a concrete roof tiles or other roof covering rich in calcium) which would then end up in the tank. Warming of this water might cause some precipitation of calcium carbonate but I would be very surprised if it were substantial. Could pore blockage be an accumulation of dust rather than calcification?

    As for the eels! I have no idea why they would help. Maybe a little respiatory CO2 would keep the pH down… Small fish in relatively open tanks can be a good idea to keep mosquito larvae in check. I’d think a couple of goldfish would do the trick though.

    The one I know of uses a panel that is direct connected to a DC motor. It pumps into a tank above ground while the sun is out and the farm takes it from the tank to its various destinations.

    I could not see a hand-pump linkage being reliable with that depth, but I might be wrong.

    I guess I was very wrong. Just found this…

    Good question

    So with this hand pump I could draw the water from the well into a tank. How would the water move from the tank to the sink?

    I was thinking about using something like this for the shower,

    That style works well, but you would need something to pressurize the system. You could pump it to a small tower and use gravity feed, or a regular DC pressure pump and tank setup…of which there are several on the market.

    Have you thought about doing a solar water heater? They are one of the simplest things to build.

    So after reading this ( https://www.otherpower.com/otherpower_waterpumping.html ) I am not so deterred from a solar powered pump.

    According to that article, All I have to do is hook up a 12 volt deep well pump to a 75 or so watt solar panel and it does not even require batteries.

    grundfos makes a good reliable 12v pump. i cant remember the specs for 250ft. in ac that would be the magic depth making a 3/4 horse pump the ideal. you could do it with 1/2. you will go from about 7 plus gallons per min to about 3 with the 1/2 hp and the strain may cut life span down. definately choose a varialble speed. in the past the pumps are realitively the same price reguardless of 1/2 or 3/4 but for 1700 plus bucks you dont want to compromise or inferior capibilitys.

    personally i always plan on the better gear from the begining. you will save money and time in the future as your desires grow. sisterns are roughly 1 buck a gallon. again go big and then you wont have to add or adjust you system in the future. surface pumping is easy 12v surflow about 80-100 bucks.

    this pump will be good to about 12 feet of lift.

    check out northern arizona wind and sun since your in the area. i have found there pricing competive but on the high side. i also think theres alot of used solar gear around lake havasu area.

    ill check out the otherpower link. my intial thouht is wy build multiple systems. youll have a 75watt pannel sittin there when your not pumping water. i lived on 15watts for 2 years. also in previous topics chowan and i have addressed if your going to be commuting to this property. you can build a extra battery system with isolators on you vehical.
