When you say "interior drain tiles" are you referring to the cheap surface mounted afterthought systems or real drain tiles that are at the level of the bottom of the footing?
Another question they replaced the bad drain tiles on the inside of the basement walls, they put clean out areas in each corner of the basement, they said to put a hose down each one about ever 3 months to flush out the drain tiles into the crock( sump pump) have you heard of this before ???
