Q: Do I need this and how does it work.? is it connected to any thing like water or just a stand?
A: This is a much easier and more convenient way to clean a cell. This item simply screws on to one end of the cell, so you can fill it up with the cleaning solution like filling a vase with water. You don't strictly need it, you can use a large bucket to clean your cell; that requires more cleaning solution and can be harder to handle.
Q: will the cleaning stand nut replace a cracked one on my salt cell?
CIRCUPOOL® CLEANING STAND FOR CIRCUPOOL RJ, UNIVERSAL, AND SI SYSTEM
can the nut with this replace a cracked nut on me cell housing?
A: Excellent question, but unfortunately no it won't serve that purpose. However, if you go in the website navigation to Replacement Part >> Parts & Accessories >> then choose your model line, you can purchase your systems threaded collar and union that would be needed in such circumstances.
Q: What is the diameter of the threaded pipe this connects to?
A: Your salt cell may utilize either 1.5" or 2" unions depending on what pipe size you have. However, this cleaning stand does not connect to the pipe, it connects to the proprietary threading on the salt system's cell. There is not an off the shelf fitting that would substitute.
