Correction
Assure permanent electrical service
(check fuse, plug, pull chain, or switch).
Replace controller.
Reset time of day.
Close bypass valve.
Add salt to brine tank and maintain salt
level above water level.
Clean injector screen.
Check brine tank fill time and clean brine line
flow control if plugged.
Repeated flushing of the hot water tank with
treated water is required.
Make sure distributor tube is not cracked.
Check o-ring and tube plot.
Replace seals and spacers and/or piston.
Check salt usage and salt setting.
See "Excessive water in brine tank".
Clean line to water conditioner.
Clean control and add mineral cleaner to mineral bed.
Increase frequency of regeneration.
Remove piston and clean control.
Assure that well system has proper air eliminator
control. Check for dry well condition.
Check for proper drain rate.
Check backwash, brine draw, and brine tank fill.
Increase frequency of regeneration, increase
backwash time.
Clean flow control.
Clean injector and screen.
Replace control.
Replace brine valve seat and clean valve.
Clean brine line flow control.
Clean drain line flow control.
Clean injector.
Clean screen.
Increase line pressure to 20 psi.
Change seals, spacers and piston assembly.
