Thanks for the responses.

Question--you make reference to keeping the filter pump outside-- doesnt it have to be outside? I do bring it inside over the winter.
The filter/pump is about 3 feet from the pool and is uncovered and obviously gets doused when water comes over the top. Can this be a contributing factor to its premature demise?

Sorry for all the questions, however if I replace I would like to revisit my chlorinating process. Right now I chlorinate with mini-tabs in a hayward chlorinator. The mini tabs are very costly and I basically have to refill the chlorinator every 2.5 days. I generally kept my filter going about 16 - 20 hrs a day. There has to be a more efficient/cheaper way of chlorinating.

Thanks again
