I have a Mineral Springs SWG installed in 2005 in my 35,000 inground pool. Looks likes the PCB board has gone bad. It shows -pcb- on the display with all lights on. If I pull all power from it it can be reset and operate again but it has failed twice now so it can't be relied on.
Pool company can replace PCB board for around $500. They are recommending I replace the Mineral Springs system with a Pentair Intellichlor system for around $1,000. They say they have less problems with the Pentair system. I know in the 8 years I had the Mineral Springs I replaced the cell once, maybe twice, not sure.
I see where the Pentair Intelliclor has the controls built into the cell and a new cell costs more then the Mineral Springs. If the Pentair will work better and last longer then I would go for it. My rule of thumb is if a repair costs more then 50% of new cost then I go with new. This is right at the edge.
What do those withe experience here say? Repair the Mineral Springs or replace with the IntelliiChlor?
Appreciate your advice.
