BEWARE!! i just got mine the same place mentioned above..the threads on the pre-filter do not fit ANY pipe at lowe's..and the hole the pre-filter goes in to drain is too small and had to be polished down about 2mm. Had to buy extra plumbing/pvc stuff last night to make it all work right. Just a caution reminder! You may not get the same one or buy it from the same place but they all look alike.
