Suction valve not in the water
Garden pump was not filled with
pumped liquid
Garden pump sucks in air at a
connection point
Leaky or damaged suction hose
Max. suction height exceeded
Waiting time was not maintained
Air cannot escape because the
pressure hose is closed or there
is residual water in the pressure
