Question 1285 Deck General

The correct answer is D) All of the above. To avoid loss of suction in a pump, you can: 1) Open the vent cock on the pump to allow air to enter and prevent a vacuum from forming. 2) Use a full tank to keep the pump primed and prevent the loss of suction. 3) Close down on the tank valve to restrict the flow and maintain the pump's prime. All three of these methods can help prevent the loss of suction in a pump and maintain its proper operation.
