This valve is in the wall between the shower and the back wall of your closet. Do not remove the shower! My dealer wanted to do that on my 3075 but I said there has to be a better way.

Open your closet door and look at the back wall for an access cover. Remove this. If you do not have an access cover you can make one yourself. If you look between the sliding door and have someone turn on the back flush you should be able to see the spray and you will know where the valve is. Measure the height and transfer that height on the back wall of your closet. Make a hole large enough for your hand to get in and remove the valve.

Hope this helps.
