I have a rainsoft water softener model # XXXXX that is over 10 years old. When the system regenerates it fills the brine tank with water and doesn't draw it back down.
Sometimes the timer will stick in a mode as well?
I am a mechanical engineer and can do the repairs as needed. Having a difficult time in locating parts and support for this system as a DIY'er.
Home is for sale and we don't want to replace system.
Please advise parts source if possible.
