e to exit the French drain is on top of the driveway. However, If the end o
f the drain exits the driveway, this severely limits the depth of the Frenc
h drain in order to ensure a slope toward the end if that makes sense.
My question is, I have seen pop up drain emitters. They basically look like
a 4 inch 90 degree elbow with a top that pops up when water pressure is ex
erted. Will a French drain product enough pressure to force the water out o
f this type of emitter since water will have to travel "up hill" albeit for
just the length of the elbow.
I appreciate any advice!
