Question filter backwash interval (should anyone filter w/o backwash head?)

'm using about 100gpd with city water in Bear, DE, with my family of four.

I have a 10" by 44" filter with about 1cf of media.

How often should I set my new control head to backwash? (see other thread if you want to help me decide on a control head)

Backstory:

My supplier in their wisdom did not provide a backwash head for my carbon filter, they said their company's MO (modus operandi) is to let customers run their carbon filter for a couple of years and then replace the carbon. Seems like a bad idea to me due to bacteria and such. Should rains**t (or anyone) be doing this?

I've been running a year so far, and I think quality has degraded, but it's hard for me to say definitively.

Thanks!

Backwashing

As long as your carbon bed is running "upflow" and has appropriate underbedding (gravel or vortech), you'll usually get about a year or so of good operation.

If you're on a tight budget & understand all the implications, the non-backwashing system can often suffice.

I personally prefer backwashing the bed every day or two to protect from bacterial growth while eliminating fines & sediment.
