Gravity Water Tank The Plumbing Is Simple

Описание: You can easily install a gravity feed water tank for your home.
It provides an un-interuptable supply of water for your home,
and for Fire Fighting.


Here is the simplest possible plumbing
That allows you to select between Pressure Water from your well,
and Gravity Water from your tank, and to fill the tank from the well.
Only one water line is required between the tank, and the supply line to the house, for both tank filling and gravity supply to the house.


Although I don't mention it, the gravity tank can also supply water to prime your water pump, after you service it. Very handy indeed.


This system depends on having the tank ABOVE the level of the house.
Water pressure is proportional to the height. 33 ft of elevation = 16 psi
Since my tank is 8 feet tall the pressure difference between full and empty will be about 4 psi.


Even 5 psi of water pressure is quite usable for sinks, showers and toilets.
but will be quite feeble from a hose.


Using this tank to fight fires requires a pump.
I have a gasoline pump for the purpose.
