A: No
Q: Does it create a noise inside the pump when vapourised water molecules implode?
A: Yes
Q: What can you add to a pump to prevent it from dry-running?
A: A float switch
Q: What can you add to a pump to prevent it from dry-running?
A: A source of airflow
Q: What can you add to a pump to prevent it from dry-running?
A: Nothing, you can only use pumps with built-in dry-running protection
