| Hello, | | I am raising my cold water tank to increase the pressure (a bit) of my | shower. The tank is about 3 meters horizontally, 1.5 meters vertically, | from the hot water tank. Is it best to route the pipe from the cold | water tank diagonally down on a gradual angle, or vertically down to | the joists, then a horizontal run?
Horizontal runs are only a Bad Thing for sewage, soil, drain, waste pipes and the like which run partially empty, but not for pipes which run full with some pressure behind them as in this case. Soil pipes etc must have some fall so that they self empty when nothing is flowing down them.
I can never understand why "head of water" is defined as from the "bottom" of the cold water tank and not the "top" of the waterline at the moment.
I raised my cold tank where the waterline was about 3 feet above the shower head to a new position where the water line was about six feet above the shower head and got a considerable flow improvement.
Could someone please define "head" for me please ? ( in this context !)
