Last week, my pool pump, which is a Pentair WFE-24, lost pressure from one day to the next. Usually, my DE filter reads about 12 PSI and there is sufficient flow to keep the water moving and operate the pool vacuum. But upon start-up the next day, the pressure was close to 0. The water still moved, the pump primed and the basket filled, but it wasn't sufficient pressure to circulate the pool current and definitely not enough to move the vacuum. For what it's worth, I noticed that the noise the pump makes is also different. Hard to describe how, but different pitch.
This pump is only a little more than a year old. Any suggestions?
