How to remove head off resin tank on culligan mark 89

To set the timer on a Mark 49 Culligan water softener to refill the brine tank, you will need to consult the user manual for specific instructions. The manual will provide information on how to set the timer to control the frequency of regeneration cycles, as well as the amount of salt that is added to the brine tank during each cycle. If you no longer have the manual, you can contact Culligan or check their website for a downloadable copy. If the brine tank is not refilling enough after cleaning, it is possible that the brine tank float may be stuck or damaged, or the water level in the brine tank may be set too low.

Call Culligan for service. You have a serious problem as it sounds like your resin bed is not going through the backwash cycle before returning to operate mode.

Normally when your water softener goes through a recharge cycle, a solenoid operates to bypass the system while brine (extremely salty water) is drawn into the resin tank to perform the ion exchange process. This is a timed process. Once it completes then your softener switches into backwash mode where the resin bed is flushed with clear water. Finally at the end of the recharge cycle the softner switches back into normal operation.

This is not something that you can fix yourself. Contact Culligan immediately.

Your local Culligan dealer is the only place to get one. You need the retrofit kit to prevent the shaft of sealpack from bending.

That depends on what part of the cycle water is going into salt tank. If it is the last cycle (refill) it is normal until the proper water level is reached. If it is any other cycle then the brine piston or sealpack needs to be replaced.

clean the drainage filter then it will work correctly again

If you disassemble the valve completely (all metal parts) the valve itself is delrin plastic and is recyclable along with the brine tank. You may be able to scrap the softener tank. You will have to get all the resin and gravel out of it. Just tip it over take the inlet manifold out and drain the resin into a bucket, take the resin to culligan for disposal.

If the unit will recharge then you might have what is called a salt bridge in the tank. The salt is stuck above the water level in the salt tank. Poor a gallon of water over the top of the salt and see if you can then break it up. The salt should go down then.

Most Culligan brine tanks have a lifetime warranty.
