|Iron Tank Valve|
It is possible to replace an existing Iron Tank Wall or Iron Tank Gauge with an Iron Tank Valve by breaking the block and replacing it; the contents of the tank will not be lost unless the top or bottom center block is broken. Therefore it is not necessary to know exactly where valves will be needed before building a tank.
Though liquid can be pushed into the tank through a valve placed anywhere in the wall, it can only be pulled out from the bottom wall or the bottom layer of a side wall, no matter how full the tank is.
