The plumbers installed all our plumbing in our walk in shower, we are suppose to sheetrock before contractor installs shower membrane and tiles. The plumber installed the plumbing so that it can be adjusted (moved forward or back) from behind, once tile is installed. Our question is the black plaster guard that is over the valves... do we remove it and cement board around the valves or do we leave it in place and cement board around it, if so do we remove it and use it as a pattern on cement board and then replace it back over valves, from what we read on moen instructions we are not sure what to do. The moen instructions are confusing ... to say the least!

The schluter - kerdi system is going in after cement board, should we use a plastic vapor barrier over the plumbing pipes etc before backerboard, we used it very where else but not sure about over plumbing.
Thanks.

No wall material should be installed where the plaster guard is and it should sit flush with the finished wall. You can verify the opening with the trim plate

Thank you for repying. Much appreciated! Thats what we thought... but needed to hear it from someone else.

We just installed what I believe is the same valve you have. The instructions said to leave the plastergard on. All you do is break off the top part that covers the upper valve. I think Moen uses the plastergard to help align the screws in the trim plate
