Kevin, The pump does not pump as in a water pump it just circulates the water, If the impeller , shat etc is turning & nothing restricting the water flow then its working, you are not going to see a gush of water . as there is clearances around the impeller. & hot water rises, Use the collar that vedors sell to set end float. as Tom states . If all does not quive you pease of mind have another Model A guy look , Spring in NZ
