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

Pellets can 'bridge'. Check your brine line connections and prevent any air
suction. If it sucks air it can't lift heavy water/brine. Yes the air check
screws off the older version of that control or you remove the screws
holding the clear plastic cap on it. The injector has to be clear/open or it
can't suck brine. There can be no kinks in the drain line. The injector
screen has to be clean. Te drain line control (ball) must be lean and able
to roll around in the drain line flow control area. The minimum water
pressure minimum has to be 20 psi. If those things aren't maintained, the
unit won't suck brine.
