Most Common Causes for Pool Pump Problems

The 4 most common problems your pool pump will face and their solutions!

The pump does not move water

If you notice that your pump is not moving water, you should begin by checking the filter, skimmer, and pump baskets to be sure they are not clogged with any debris. Another part that can become clogged is the pump’s impeller, the part of the pump that actually moves the water. You can check the impeller by opening up the pump. Another potential cause of no water flow is that your pump might have a leak in the suction line, and therefore is sucking air instead of water.

The pump is sucking dry air

If you notice air bubbles coming from your pool returns, that is a sign that there could be a problem. One cause could be that the water level is too low. If this is case, air can get into the skimmer lines and then be sucked into the pump. Another cause could be that the skimmer is full of debris and is clogged, which can lead to the skimmer opening being blocked. This, in turn, forces air to be sucked into the skimmer line. Other causes for air getting sucked into the pump could be loose hoses or an inadequate seal on the pump lid, an o-ring, or a drain plug.

The motor is very loud

This unwanted noise is usually the result of your pump motor needing new front bearings. While this is the most common cause for a noisy pump, the noise can also happen if the pump impeller is spinning very quickly without enough water. This is called cavitation and in this case you would want to check for a clog or closed valve.

The pump is losing power

If your pump seems to be struggling to pump water or does not pump as much as it used to, it may just be worn out. Over time, older pumps can begin to deteriorate and lose power. In other cases, you might just need to clean the filter or have it backwashed.
