04.
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
05.
Q: Why is it an advantage to mount your pump to a fixed base?
A: A steady pump operates more efficiently
05.
Q: Why is it an advantage to mount your pump to a fixed base?
A: It makes it easier to measure the pump data
