Where to drain an Iron Filter

[JustaDIYer]

Could I get opinion on where to drain the iron filter? septic or sump? Both are readily accessible. The softener is currently drained to sump crock. Iron filter would regen every 4 days (approx. 100 gal ?) If I tied into main septic line (directly above the filter), how would I do that (I realize I may need a plumber for this one)? Or possibly tie into the sump drain where it exits the house (bypass the pump)?

How much more usage would an additional filter draining to the sump put on the sump pump? Current sump pump is about 4 years old.

Thanks all!

How much more usage would an additional filter draining to the sump put on the sump pump?

Maybe 50 or 100 gallons every 4 days.

It should not go into the septic tank. You could pipe it to surface discharge into the woods or into you sump pit. Where is the sump discharging ?

Don't have woods available to pump it to. The sump discharges into a pipe that goes underground outside of the house, not sure where it goes unfortunately. My softener is currently draining into the sump now which gets pumped out. Running a drain line into the sump is the easiest way to do this, I'm just wondering the additional work load on the pump (an additional 100 gal every 4 days).
