Once the valve is installed there is no reason to remove it. And you do not want to use compression fittings inside the walls. Use 3/4" X 1/2" reducers, reducing elbows, or male adapters whichever works best for you. : I am plumbing a new bathroom for our house. I bought a Grohe thermostatic valve, for the bath and shower. : This valve has 1/2" FIP inputs and output. I have my two water lines coming off the floor, both 3/4... now what? : What type of fitting do I use to adapt the copper tubing to the (brass) valve body? Simple male thread? That would mean that once the valve is installed, I cannot remove it short of cutting the supply lines? : Or use a MIP to compression adapter? I would need soft copper tubes for that, right? Hard copper and compression angle stop. : Also, what is typically used for the sink and toilet angle stop? Soft copper and compression angle stop, or 90 ell, brass tube and threaded angle stop? : Thanks.
