welcome to the world of SWC
.....check some of the laguna pond pumps at freshwater stores.....thats what Laurie ended up buying when her pump died.....you need to be really careful tho as at some point either the pump body or the volute on the skimmer changed....we had a bear of a time finding a direct replacement......
