The ZVA Sidewinder™® Tube Skimmer is another popular skimmer manufactured by Zebra Skimmers that fits into tight spaces. Models available are ZVA8-08, ZVA8-11, ZVA8-14, and ZVA8-17. The ending number represents the reach of the tube. Reach is not the same as overall length (circumference). The circumference of a tube is (reach + 7) * 2, an 8″ reach tube is (8 + 7) * 2 = 30-inches in circumference. The following information will help you determine the reach of a Sidewinder™® for your sump. For optimal performance of your Sidewinder™® we recommend the tube not be longer than the depth of your sump.
- Reach is measured from the base of the Sidewinder™® mounting plate to the bottom of the tube.
Example 1: You have a sump with a depth of 10″, allowing for some clearance from the sump bottom then a ZVA8-08 would work.
Example 2: You have a sump with a depth of 12″, allowing for at minimum a 1″ clearance off the sump tank bottom a ZVA8-11 would work.
Example 3: You have a sump with a depth of 20″, allowing for the tube to be off the sump bottom a ZVA8-17 would be sufficient.
