How does one design a booster system to boost water to a roof-mounted tank for a gravity-fed system?
Our standard HydroPak booster system will do the duty, as long as its specified to be a special “tank filled” booster system. What this means is, the control panel is fitted with 5 floats (4 if supplying water from the city main). 1 float mounted on the suction side of the system if water is supplied from a reservoir, and 4 floats mounted to the tank. These 4 floats send signals to the panel, which control the activation of the pumps. Check valves are required instead of PRV’s. Great care must be taken with the calculations, making sure of the correct suction pressure, in order to select the proper size of pumps that will perform the desired duty.
