Can an in-ground pool pump malfunction one day and work fine the next?

Yes, it is possible for an in-ground pool pump to malfunction one day and work fine the next. There are a number of reasons why this could happen, including:

  • Electrical problems: The pump may have a loose wire or a faulty connection. This can cause the pump to stop working or to run intermittently.
  • Mechanical problems: The pump may have a worn or damaged part. This can cause the pump to make noise, vibrate excessively, or leak water.
  • Air in the system: If there is air in the pump or the plumbing, it can cause the pump to lose prime. This can make it difficult for the pump to circulate water.

If your pool pump is malfunctioning, it is important to troubleshoot the problem and fix it as soon as possible. A malfunctioning pump can damage your pool and equipment.
