I have looked several times over the past several months, but was disappointed to not find a pool pump rebate program through my power provider, PEPCO. My wife just sent me a link, and according to the form, it looks to have started May 11th. To qualify you need to replace you current pump with a dual or variable speed energy star certified pump. I was interested in just a motor replacement in the past, but this might push me toward a complete pump replacement.
