"It looks like not a alot of water is going thru the socks. It probably won't hurt anything since you have the mat over the drip plate but, is there anything you can do to get more water to flow thru them? "
I bet the side of the socks may be pressing against the walls of the pvc pipes cutting down on the flow through them. If you took the 4" pvc pipes and drilled a ton of holes in them it would probably help the water flow through them greatly.
