Models: All pumps
A common cause of pumps failing to prime is air leaking at the hose fittings.
A simple way to check this is to remove all hoses, fill the pump with water, start the motor and place a damp but firm piece of cardboard or a sheet of rubber over the suction port. If suction is felt, check the camlock or nut and tail seals, also the hoses for holes. Note: If the pump is fitted with a female camlock this test will not work.
