Q: will this replace a Pentair ic40 with out cutting plumbing except for flow switch ?

Asked by: butch - 6/12/2017
A: If you are switching from a Pentair IntelliChlor model, most people actually prefer the CircuPool SJ models. They have an adapter kit to connect to your current fittings, so it takes virtually no work to make the switch. Operation will be very familiar, but it has some other benefits as well. The SJ cell is clear so you can see it working and check it without having to disassemble everything. The SJ does not require acid cleaning like the Pentair. Even better, when it comes time to replace the cell, the SJ cells are much less expensive.

Q: I have a Resilience salt system and I believe it's beginning to fail. Parts are hard to find and expensive. How much of a job would it be to replace it with this?

Asked by: Gary - 6/20/2017
A: It should be a fairly straightforward job. The electronics should be equivalent in terms of the way it is connected to power, and the cell is similar and also straight in-line, so the plumbing would just need to get cut so that you can glue in the unions for the new cell. I would expect about an hours worth of work.
