Recently HydraSleeve users have expressed much interest in using the SuperSleeves simply to gain more volume from sampling a 2-inch (Schedule 40) well.  Our large SuperSleeve holds more than 2 liters and fills within a 5-foot zone; the small SuperSleeve holds more than 1 liter and fills within a 3-foot zone. The SuperSleeves are designed with a 1:1 fill rate and are typically sold with a SuperSleeve Top Weight to compress the sleeve into the bottom of the well.  However, there are circumstances where you don't really need the compression, yet you would like to use a SuperSleeve for maximum volume - or a combination of two SuperSleeves with one compressed in the bottom and the other suspended above this in the well. 

So how do you attach a SuperSleeve to the tether if you don't need the SuperSleeve Top Weight?

We would like to introduce the SuperSleeve PVC Collar which can be used just for this purpose.  See the components above.  The SuperSleeve threads into the collar just like the top weight, however it is not heavy enough to compress the sleeve. It consists of two knurled pieces of PVC which thread together and a spring clip is included with each collar.  The top portion is exacly the same as the top piece of the SuperSleeve Top Weight; the bottom portion is a simple PVC threaded ring which takes the place of the stainless steel portion of the SuperSleeve Top Weight.

A great example for using  these collars would be when you want to sample a complete 10-foot zone using HydraSleeves.  This can be accomplished by using a 2-liter SuperSleeve complete with a SuperSleeve Top Weight at the bottom of the well and then suspend another 2-liter SuperSleeve directly above that using the SuperSleeve Collar.  When you retreive the two SuperSleeves the result will be a complete "core" sample of water from top-to-bottom of a 10-foot interval.  Careful decanting can deliver a vertical profile of the entire 10-foot zone.
