Drain Question

[RemainVayne]

I'm looking to plumb a 2" pvc line that will run from my sump to my basement floor drain. This line will serve two purposes.

#1. I'll be adding in a a tee so that I can insert a drain hose when doing water changes. This will allow the water to flow through straight to the floor drain.

#2. This is my main question. This line is plumbed into my sump to serve as an overflow for an auto drip system. I want to add a check valve in this line, but will the trickling water draining through the line (from just the overflow water due to drip, not from a large water change) be able to flow past the check valve? Or will there not be enough pressure to get past the valve?

Sorry if this is a n00b question..

Are you expecting back flow from the drain?

Not necessarily expecting it...

However, that drain has backed up twice in the 6 years I've lived in this house due to root growth. Not a ton of backup, but I'd rather the backup goes onto the unfinished basement floor than into my sump.

Just put an air gap between the end of the 2" pipe and the drain.
