window well drain, distance to bottom of window

hey all

I installed a window well last week... tied into the drain tile with a T and went up t my window with a 4" PVC pipe.. .
now I cut the top of it about 12" from the bottom of the window
covered it with a drain cap and put landscape material over top of it and laid more gravel on top.. .so right now there's about 6 inches of gravel on top of the pvc pipe.

should that drain be set higher? if so, what would be the purpose since the entire thing is siting in a deep bed of gravel...

If you are reasonably certain you can unclog any problem that far down like leaves, etc. and the water flow is unobstructed, it won't present a problem. If the landscape cloth covers the opening, then dirt, etc. will accumulate and will eventually cause a pool to form before it drains. Having it higher may alleviate that.

Drains are normally set just below the lip of the window ledge to allow for a small amount of accumulation and drainage. There's no set definition. Just whatever you feel comfortable with and what you feel will drain properly. I was just cautioning about covering the drain with landscape cloth and it's ability to collect dirt and other contaminates. Keep things clear. It would be easier if the drain were more easily accessed.

So…what is the main purpose of that drain? To catch water IF it gets that high? Meaning any water entering the well is allowed to seep into the earth and slowly make it’s way to the foot to be eventually carried off by the drain tiles?
You would think that diverting most of the water that falls in the well into a drain would be better as it would keep water away from the house.... no?
