I am installing Pex in my house. I am using a home run system. I will have 1 outlet on the cold water manifold that I will not be using. Instead of capping it off I would rather just use the last outlet. My plan is to connect (2) 1/2" water supply lines together using a "T". then Run the water line to an outdoor spigot. My theory is that water would flow through both 1/2" water lines equally anytime my outdoor spigot was used. I am just trying to prevent water stagnation and make sure all water lines are being used.
