I am in the process of finishing my basement bathroom and would like to do it all myself. However, our water lines are run through a pressurized brass "water manifold" with rubber tubing used for the water lines. Apparently a special tool is needed to add water lines to this "manifold" but I have no idea what it is called, what to look for or where to find it. What is the name of this tool and where do you think I can find one. Thank you for you help.
