My buddy did this with his 10G MLT, to add to reliability, he shoe-horned a couple 1" sections of CPVC an inch or so from the T-fitting of the manifold. The were drilled with some 1/4" holes to ensure drainage, and did so with those 1" sections in 2" spacing(roughly, from memory) all the way around. He uses a wooden mash paddle and has never had an issue.
