Why is my Hayward pool pump so loud?
Why is my Hayward pool pump so loud? One of the most common causes for a noisy pump is that it’s running dry. This can happen for a few reasons—the most common of which have to do with the skimmer plate built into the side of the pool. If your pool water level has fallen below halfway down the skimmer, your pump might be sucking in air as well as water.
