Water Softeners and Air Filtration Systems - Help repairing a 18 year old Kinetico waterplant

I have an 18 year old Kinetico waterplant. It is a twin tank softener with built in RO filter for drinking water. The water pressure in our house (coming out of the softener) has decreased considerably and I am told that the Kinetico system needs to be replaced because the resin in mush and restricts the water flow.
They sent a sales person to sell me a new system. Can I replace the resin and revive this old system? I have just replaced the the RO membrane and carbon filter.

First of all, yes, the resin can be replaced....I wouldn't purchase a new system, and would rather have a service tech out there than a salesman.....secondly, i have a question....you claim to have a softener with a built in R/O???

Yes Kinetico at first had one unit that had a R/O filter in the same cabinet as the two Resin tanks. Then the water from the R/O went to a charcoal (MAC) filter and finally to a 5 gal storage tank.

The WatrerPlant was a funky little model that had a softener and an RO built into one unit. It was great for RVs and other small, tigh locations. Kinetico stopped building them years ago.

It is totally rebuildable. Some partsd may be hard to get but not impossible.

Where can I get parts for the Kinetico system? I have found very few listed anywhere.

They still offer parts for those units from Kinetico.
