I went through quite a few electric pumps before I got fed up with them dying so quickly. Tried several different brands but the same result, they seemed to last less than one season before they started leaking or died outright. I then bought a Hobbico hand cranked pump. I've had it now for 4 years and it's still going strong. I wouldn't use another electric pump it if was given to me free.

Hope this helps
