ANSWER FIRST
Build a schedule from the installed models
Treatment maintenance should follow the actual equipment manuals and operating conditions. A softener needs salt and operational checks; an RO system needs cartridge and membrane service; carbon and sediment stages have their own replacement triggers. One annual visit does not automatically cover every consumable.
Keep a log of installation date, model numbers, baseline tests, filter changes and repairs. Pressure loss, unusual cycling or a return of symptoms calls for diagnosis. Bypassing faulty equipment may restore supply but also changes the water delivered to the home.
