Moen shower control problem

if it were me, and i just bought it, i'd take it back.

AJ,

I just finished installing some Moen shower faucets myself. One of them was like yours, just a trickle of water. I fixed the problem by disassembling the valve, and cleaning out the little pressure balance piston inside. Probably just clogged with plumbing debris. Once it was cleaned and reassembled, it worked fine.

Since this is described in the installation instructions, I assume it's a fairly common problem.

Oh, one other possible cause, the handle could be on upside down.

I would suspect that as well. Moen's instructions describe flushing out the water line with the cartridge removed before using it for the first time in order to avoid this.
