Longest Life of T15 Cells?

Just checking in with those long-time SWG users - Who has the oldest TCell15 that is still working? I installed mine beginning of 2012 season, and it is still working. I run my pump at 100% for 12 hours, salt generation at 30% in my 20,000 in-ground vinyl pool. I think oversizing the cell and using at lower percentages and cleaning are the trick. I also remove and put it indoors during Central PA Winters. How are others doing?

salt generation at 30%
65,

Just in case this was not a typo..

Salt cells do not generate salt, they generate Chlorine. :mrgreen:

I think your location is the primary factor. We always recommend that a cell be rated for at least 2 x the volume of your pool, so in our minds, your 40K cell is the exact size it needs to be.

Thanks,

Jim R.

2 and change hours on mine at full throttle costs the same as 24 hours of 1200 RPM. Is there any reason to run it 100% ? Slow and steady works wonders for poolcare.
salt generation at 30%
So it's only producing chlorine for 3.6 hours a day. (30% of 12 hours). It'll take a while to reach 10,000 hours with the short PA season. The cell doesn't care if it's run 80% of 4 hours 45 mins, or at 30% of 12 hours. Any equivalent maths are the same hours off the lifespan of the cell.
cleaning are the trick
How and why do you clean it ? I ask because my PB (and the cell itself said) to frequently acid bath it. I never once had scaling and ignorantly let it soak in straight muriatic acid for 6.5 hours over its lifespan. It was no surprise it failed 4k hours early when I learned better.

I didn't state this, but my pump is only a dual speed. I run it on high for 12 hours. My low just doesn't seem to have much power. To clean, I just plug one end and dump muratic acid in it, let sit for 30mins or so and then hose it out. I don't inspect it, just a yearly habit. Overall, I based the 30% chlorine setting on my chlorine PPMs over the first couple years. Seemed I was hitting my sweet spot of 4-5ppm dialed in at 30%.

Ahhhh. Ok. Please fill out your Signature. It helps us ALOT to not have to ask questions about your questions. :)

Cease this immediately. If you don't see toothpaste like scaling on the plates, do not clean it. If you do see buildup, use a popsicle stick or such to knock as much off as you can. Then use Vinegar for the rest.

My original cell said right on it to clean every 3 months, which the PB concurred. They were wrong. The new cell says to inspect and clean when necessary.

The daily UV demand changes over the season like a bell curve, with little loss at the ends and more in the middle. But every season is different. Last year I needed one setting for 10 or so weeks. Usually it was 4 or 5.
 
FYI - My cell finally died. It was coming up on its 12th season. Got more than my monies worth out of it. Then I went to buy a replacement, and Hayward only has the T-Cell-940, basically an "extended life" version of the T-Cell-15. I shopped around, and best I could find was $1250. OUCH! Keeping settings same, and cleaning routine same. lets see if I can get some life out of this unit!
