Mark E Industries Quick-Pitch Kit QPK-101"GOOF PROOF SHOWER"

Do you need both Pre-Pitch and Quick Pitch? The Mark E videos seem to imply that, but wouldn't that double the pitch to 1/2" per foot?

Does this kit come with the weep hole protector?

Do you tile right over the quick pitch and is there any issues with the tile not bonding to it?

Has anyone had leaking during a flood test, from the center leveling ring being position on top of the drain flange, but not sealed from the inside?
