retaining walls and weeping tiles

Hi,I am building a 3 foot retaining wall with allan block to divide my side and back yards.The side yard tends to slowly slide .exactly where should i lay the 4 inch weeping tile? level with the base of the bottom stone?slightly above or below that? and how far behind the wall should it be from the base stones?Thanks

The lower, the better, if it is parallel to and behind the wall. The drain pipe (holes down) does not have to slope, but must have free drainage at one end. Rock backfill insures a good installation.

The natrural gaps in the Allan Block also provide good drainage from behind the wall, but you cannot beat good drainage around or under any wall or foundation.
