I figured it out. Nothing is broken. We didn't run a pool filter until maybe late June early July last year (which is not usual for us and I totally forgot about the pool situation). Our pool is usually opened in early May, closed in October. I figured it was a weird fluke and then remembered the pool issue once I put more thought into it. But wow, thats a lot of increase. The pump/filter runs more than it needs to because we use it as a water feature (nothing grand) I never knew and dont usually pay attention. We have a small well insulated house, practically a cottage.
