Does anybody have any experience with the SW15? I'm thinking about trying the cheap route while I wait for something like black Friday to get a deal on some Tunzes.
Try removing the ceramic ring at the base of the impellers magnet. See if that doesn't help?I ran a pair of RW-15 pumps since they first came out. Recently one of them failed and I purchased the SW15 pumps. The SW-15 pumps are smaller than the RW-15, but when compared side by side when opperate, the SW-15 is noticebly louder. Not sure why the diffence in sound.
