2-inch Spring Clip - recommended for the top of the HydraSleeve |
Don't use Spring Clips in 2-inch Sched 80 wells or when there are obstacles Spring Clips are altered slightly for this size HydraSleeve. They are made a little wider for the larger bag. If yours don't seem to fit, simply pull on the ends to make the spring clip wider. |

If the well is more than 250 feet deep, or there are obstacles down hole, you may want to use heavier than 8 ounces. Also stringing multiple sleeves on one tether requires heavier weight. |
Weight Selection Chart |
Top weights are not available for this sleeve. Use 1-liter SuperSleeves as the alternative |
Top weights would be needed for short water columns less than 7 feet. See 1-liter SuperSleeves if your wells have less than 7 feet and you need ~1 liter of sample. |
