Need Help - installing domestic Water Tank

[melchi]

Dear All,

I have just bought a domestic water tank and need some advice. I would like to set it up on the roof of 2 storey building as in my region water supply stops regularly.

I want to use gravity for the distribution and won't use pump. My main water supply should go directly into the tank and to other outlets such as shower, toilet, kitchen....etc.

I only need water stored in the tank during water supply cut. Does any one has a better way of doing the installation?

Please find below a schematic I was planning to proceed with:

Is there a way that water in the tanks flows out automatically when the main water supply is cut? Else each time the main water supply is cut I have to get on the roof to open the 'stopper' or close it.

Thank you.

Best regards,
Yannick

you need a flow switch and a honey well control valve.

the flow switch should since flow/no flow of water into your system, and tell the honey well to open on a no flow situation

Your pressure isn't going to be so good. Each vertical foot below the water level in the tank will be good for .433 pounds.
