I recently retired and have too much time on my hands and I'm trying to reduce costs wherever possible. I have a 13,000 gal pool with attached jacuzzi and no water features and 2 inch plumbing. I have The Pool Cleaner which is attached to the skimmer and the bottom drain is plugged off (at the skimmer) so the only flow to the pump from the pool is from The Pool Cleaner. The suction valve by the pump is set to approx. 85% pool and 15% jacuzzi. My pump is a Whisperflo WFE-6 and it's been whispering at me (every day for about 4 hours) to find out whether it should be replaced with a more efficient setup. Any recommendations on a new pump, more efficient motor or do you think I have too much time on my hands? I'm fine if it takes 2 years to get a ROI. thanks in advance for your assistance.
