Perforated drain pipe question

I would think you will be fine.

To prove the method I described works, a couple of years ago a 2" water ling broke above a 13' tall retaining wall. The wall was sprayed with waterproofing (which is more like damp proofing) had a layer of drain mat and the described foundation drain installed on top of the footing and also at the bottom. The water line was under roughly 75 psi and we didn't find the break for 4 days. The water undermined a set of concrete steps going around the house and the front porch and all the flag stone dropped almost 18" When I went into the crawl space expecting to see a disaster it was bone dry.
