I'm a fairly new pool owner (ok...2 years, but still learning). When our pool was built they installed a Pentair Letro Legend - and it has done a great job for the most part. We noticed it was not backing up last summer, read a lot and replaced the back up valve. Had the same issue and replaced it again a few weeks ago - but it is STILL not moving well, gets stuck in one place most of the time. The tail spews water into my screen room and on anyone standing around the pool. I read to tighten the hex screw on the tail so adjusted that - still spewing. Now I'm reading that it may be the wheels or bearings? Suggestions and solution ideas?
