I have a Pentair WFE-4 that is less than 2 years old. Today I noticed that it's pumping in surges, that is, every three seconds or so it cycles between 20 psi and 0 psi. I've eliminated the filter as a potential issue by turning the Jandy valve to drain and the problem persists. Anyone have a suggestion?
Thanks in advance.
