I was reading up on this and it I am thinking this might be the result of the beads becoming worn down from friction and somehow they are able to pa ss out during the backwash cycle. I read something about that online but I 'm not sure if it is my problem. The unit is probably about 5 years old at this point.
If anyone can shed any light on what might be the problem here or point me to any online explanation I would appreciate it.
The repair guy is coming Monday and I want to understand it better before h e sells me a brand new tank or some other type of system.
Thanks in advance.
