wet set shower membrane

[Steve7700]

I have a question. My tile guy set his shower membrane in the weep drain, then the rock board over the membrane. All seems well. One thing he did do that I question is that he fastened the rockboard through the membrane, slightly below the top of the mortar bed but well above (2 inches) the weep drain. Will the holes it the membrane that are 2 inches above the weep drain but below (1/2 inch) the top of the shower floor ever be a problem?

I take it are not uk based , weeps holes IMO should not be compromised but I am concerned about puncturing the membrane ?

that is what I am wondering. if the holes are 2 inches above the weep holes would the water level ever get that high?

That depends on the fall and the ratio of fall to flow of the drain.

its drops about 3/4 inch over 2 1/2 ft all around (5'x5' shower)

Unlikely I'd say, but a better question to ask on the John Bridge forum I think.
