We have Hey 20,000 gallon underground  water storage tank with a 40 foot long 4 inch supply line to wait half horsepower electric fire pump at an elevation 18 inches lower than the bottom of the supply tank which is approximately 10 feet deep. 

 Question #1 

Is pressure testing required for this line which is not under system pressure, and if so, what psi testing is required for the line?


 The tank has a vent and sight assembly in plain sight above grade. 

 Question – is an electric low flow float alarm required for this water storage tank?
