I'm pretty sure that is a Sams-only brand, with non-standard pump and filter . . . which means none of us know exactly what you have. I'd say, send a picture, but I'm starting a 2 week focus on critical server issues, so I won't promise to get the pics posted quickly. But, you can send them to poolforum AT gmail DOT com.

Your BEST bet is to go the mfg site. If the Sams product is just a relabeled Intex, you may be able to get info on the Intex site.
