Hello,

I have a water softening system that has an Autotrol series 255
valve/460i. Its 5 1/2 years old.

I use Potassium Chloride pellets in my brine tank. I check the brine
tank regularly and have been noticing lately that the pellets are last
an extra extra long time. I doubt there is any chance these pellet
can bridge but I stired then up anyway.

I manually ran a cycle and noticed that when it gets to the cycle that
sucks the brine in through the Air check housing it only takes in
brine for a few minutes - the level in the brine tank only goes down
about .25 inches. After that few minutes the brine stops coming in an
it sounds like its just sucking air. I've never watched a cycle when
it was in working order but I assume it should be taking in more brine
than that - correct?

I cleaned the injector and the screen. There was a lot of gunk on the
screen. I was going to clean the brine control too but was not sure
how it comes off - does it just unscrew?

Cleaning the injector and screen did not solve the problem. Any other
ideas of what might cause this?

I appreciate any help/tips.

Regards
