Shower valve install
I'm working on finishing out an addition to our home. I had a plumber ruff in the plumbing and know I have to install the shower valve. The question is do I have to have a section of pipe going above the valve and capped like the plumber did for the sink. Basically I have two straight pipes coming up form the floor I will have to 90 into the valve body. Do I use an elbow or use a "T" go up about 12" and cap like the vanity. Thanks Robert
