I am in a similar situation, and based on my experience I don't have a lot of confidence in the Compupool CPSC series.
Here is my history with the Compupool CPSC-48:
October, 2011
Installed, no problems working fine
May, 2012
Cell melted through at red terminal, causing breach in cell and water leak.
The red plug end of the cable also melted.
Cap that covers the end of cell where power cable plugs also became extremely discolored and I found out later brittle.
Compupool replaced the cell under warranty and sent me a new power cable.
June, 2015
Cell melted again, unfortunately not under warranty.
September, 2015
Cell melted again.
May have been caused by changing salt production to 100% a few days prior. I had heavy bather load and low FC, plus lots of sun shining.
In summer I usually run at 70-80%, winter at 30%.
This time it caused more damage. The clear plastic housing near the electrode connection was melted, not all the way through, but near the threads.
I am really frustrated with this thing, I wish I had opted for a more expensive, more reliable brand.
I was able to repair it, though I consider it temporary, I just hope it lasts long enough to replace the entire SWG with something I trust.
Here is what I did, and it is actually making chlorine and not leaking:
My cell had a complete, through and through hole that was obviously leaking.
The cylindrical terminals can be unscrewed, don't be too rough.
I took it apart, cleaned off all the burned plastic, and used marine grade silicone (regular silicone should work, ACE had a tube so I thought would be better) to seal everything inside that comes into contact with water. I was very liberal, covering all 3 terminal areas with the silicone.
I put it back together, screwing the cylindrical terminals back on.
Where the hole was, I used epoxy to seal it. I put it level, and used 5-minute expoxy (the kind you mix resin+hardener).
This closed up the hole and sealed it from both sides.
Just to be safe, I used another layer of JB-weld epoxy on top of the previous clear on. Probably not necessary, but I wasn't sure which one would tolerate heat better.
Luckily my terminal plugs are all usable, though the red is misshapen due to melting.
So in summary, you can try a quick fix of using epoxy to seal it on the outside and silicone on the inside, this may give enough life until you get a replacement.
