I am kinda losing faith in my Dolphin. I have had my ES 3500 for 2 years and I had to replace the rocker switch twice! I don't turn it off that often...maybe 3-4 times a year and it just wears out in that time. The REAL problem is i can't find the switch local and have to order it from the company in Florida...pay overnight shipping so it costs about $80 each time this happens.:evil: Has anyone else experienced this with Dolphin pumps?
