Actually, unless you made a habit of checking your readings regularly and while the cell was actually generating, you probably would have no indication of the slow changes over time.
Why can't you rebuild it? Just have to reseal it, right?
Having had issues with a circuit board and inrush limiters, it's been on my radar screen. And I've been watching more closely as we went 2,3,4 years past "normal" lifespan.
The problem with resealing it is getting it apart without destroying it. As is you would need a <1mm kerf, or a perfect fit sleeve, to reassemble it. Even then, you need to keep the OAL the same to fit/seal in the existing installation.
I think the Aquarite units output current/voltage readings. However, the Aquarite would only display the aggregate voltage and current across all plates.
The 2 cathodes are bonded, and the other 10 plates are unconnected. There is only one potential to measure.
A new Hayward T-15 cell sells for $400, (not $500) and nine years of service makes your chlorine cost about $45 per year. Sounds like a bargain.
Monthly payment is how car dealers sell cars at retail. $200 saved is $200 earned. My $200.
Plus, we throw away too much stuff. Repair for $400 or replace for $500, and 95% of Americans throw it away. I'm not a tree hugger, but unnecessary waste is terrible for the environment. A reusable modular housing would have kept 75% of this unit out of the landfill. Connector, cable, housing, sensor. Only the plates and plate frame needed replacement.
And did I mention that I'm a geek at heart?
But he chopped it open with a hack-saw....
Table saw, actually.
I would suspect that your salt level is much higher than you think it is.
Considered that when it croaked. The last reading of the old cell (2800), and the stable instant reading of the new cell (3000), differed by 200ppm.
