You know what, "hissing" is a better adjective to describe the noise that the pump is making. I used the word "buzzing" in my original post because that is the adjective that I saw used in other threads posted on the subjet.
But in the end, it does more "hiss" than buzz. Is there a difference as to the operation of the pump?
