I debated posting in this thread because it's a year old, but basically the same problem and I worked through the same steps. https://terrylove.com/forums/index.php?threads/fleck-7000-sxt-brine-fill-fails.80581/
I also used two Pentair Youtube teardown vids.
Details:
1 cuft /32K
BLFC: .250
DLFC: 2.0
Injector: Violet
Capacity set at 24K
BW: 10
BD: 60
2nd BW: 5
RR: 10
BF: 12 (Usually 8)
Well water 28 grains softener set at 30.
1 cuft Pryolox Filter before softener.
Everything installed 9/2016
Well pressure 45-65
No pressure or flow changes at any tap. Pressure gauge after softener never goes below 40psi.
Well delivers 12+ gpm and utility sink right next to the softener delivers 8.5 gpm
I've been running out of soft water for the past month or two and kept forcing regins with it showing at least 1/3 capacity remaining.
I pulled and checked the screen and injector, thoroughly cleaning both. I even tried replacing the yellow part off a white injector I had. Pulled resin tank valve and air stop thinking something was clogged, soaked air gap in vinegar, all working properly but still no fix. Also checked/cleaned and eventually just removed the BLFC. Ran line strait to bucked and only got 5 quarts during a 12min brine fill. Pulled backing plate and brine valve and it was perfect and spotless, greased and reinstalled (inner O-ring is in place). While at it I decided to pull the piston, seals and spacers. All good, greased and repacked. Reassembled everything and checked brine flow again with BLFC still removed. Got almost 6 quarts during the 12min BF, did this again with same results. Also it used to air stop around 15 min during the 60min BD, Checked 2x and it is now taking 30min. The two have to be related.
There is a rust coating in the injector/screen area and two of the piston spacers, but it just a coating and nothing excessive. Like I said, the screen and injector were thoroughly cleaned.
Just curious, how much water should come from the brine fill with the BLFC removed? I would think it would be quite a bit.
As I was typing this I let it regin for a 3rd time to check BD and BF times. BLFC is in place. BD is still 30min and BF still set at 12mins. After it was all done I had to manually add 5 qts of water to get it to my usual water lever mark. This mark is where it usually is at with 8min BF, should be 2.5 gallons. I never add more than 2 bags at a time so I can brush the pellets back and see the mark.
Thanks again. *thumbs up*
