Lastly, the meter might be clogged with debris, in this case, remove and clean the meter.
Why is there intermittent brine draw in my Pentair AUTOTROL 604?
If your Pentair Control Unit is experiencing intermittent brine draw, it could be due to low water pressure. Maintain a minimum pressure of 1.3 bar (20 psi).
Why Pentair AUTOTROL 604 Control Unit backwashes at excessively low rate?
If your Pentair Control Unit is backwashing or purging at an excessively low or high rate, it might be due to an incorrect drain controller being used. Replace it with the correct size controller. Another cause could be the absence of a drain line flow controller; install a drain line flow controller. A restricted drain line could also be the culprit; remove the restriction.
