Step 5 · Installing the PEX Manifold

This is the step people usually slow down on. Go finger-tight first, then a quarter turn. No rush — replay the clip whenever it helps.

Select a suitable location for your new PEX manifold, ensuring it is accessible for future maintenance. Mount a piece of 3/4-inch plywood to the wall studs to create a solid backing board. Use a level to position the manifold on the plywood and secure it firmly with screws. The manifold will have a main inlet for the hot water supply and another for the cold. Each fixture in your house will have its own dedicated port on both the hot and cold sides of the manifold, each controlled by a small ball valve.
