Also known asroof tank
A house with its entry in the South-East (Agni kon), an underground water tank in the South-East and the floor sloping to the South suffers constant quarrels. Close the South-East underground tank at once and correct the slope; the staircase above it can stay.
If an overhead tank sits directly above the bed, paste a thin layer of muscovite (mica) on the ceiling or fit a wooden ceiling.
Either leave the house or treat it: close the South-East underground water tank immediately and correct the slope. The staircase can stay. An overhead tank in the South-East is acceptable.
In the same places prescribed for underground and overhead water tanks; there is no separate location, whether the water is for the labour or for the owner.
Yes. Above floor level it works in the North and in the North-West, and in the North-West it can also be built high up like an overhead tank. A tank at ground floor that is raised, with no pit, is acceptable.
Yes. Not knowing makes no difference: the sun gives its rays whether or not someone believes in it, and a person who knows nothing of vastu still gets its doshas. A wrongly placed tank, boring, septic tank or sewer line affects the residents whether they know about it or not.
Not in NNW. An overhead tank can be built from the West up to the North-West; making it in the South-West, as many people do, is wrong. Build it in the North-West.
Only if the stairs are in the North-West; otherwise not. Basically an overhead tank should not be built over the stairs, because hydro currents move as you walk below it and the mind becomes unsettled.
Yes. Water stored anywhere, including on the roof, represents the water element. But if the tank is built in a square shape, it moves to the earth element, because the square is the earth element's shape, and it becomes an earth combination.
No, it will not have any effect. Only the roof directly above the bedroom should not carry an overhead tank.
Paste a thin layer of muscovite (mica) on the ceiling, or give the room a wooden ceiling. Sleeping under an overhead tank generates hydro currents that raise the risk of heart problems.
It should not be underground; keep it overhead, in the West direction.
