The Classic 150EXT skimmer requires a feed pump to feed water to the skimmer. The recommended maximum flow rating for this skimmer is 400 GPH. These numbers are based on zero back pressure on the output plumbing. If you add 90° bends on the plumbing back to a sump you may need to back off the amount of water being feed through the skimmer. We recommend that you use a ball valve inline from your feed pump to the skimmer allowing you to control the water flow.
