It is also ideal to have them at the bottom of each manifold. They should be within the confines of the manifold cabinet. The main difference is the location of the drainage spigots. This includes one of the biggest lessons learned here in this post: Sanity Saving PEX Manifold Installation Tips. Here is a diagram for how we would design the same plumbing manifold if we did it again. Here is the PEX water manifold with each outlet labelled: How we designed it–and influence how you want to design your own–is best discussed by looking at the installed manifold itself. This house has a manifold cabinet with both the hot and cold water lines housed together on an interior wet wall of the house.

We’ve been asked a couple times to diagram the outlets in the PEX water manifold we shared here: How to Build a Whole House Uponor PEX-a Manifold. Do not forget to include a drain spigot at the bottom of both the hot and cold water manifolds.The longer the distance the more cooling takes place before it gets a chance to make the longest hot water run. Also consider the distance from the water heater to the hot water manifold.Where are you planning on installing the manifold? Is it in a central location so the master shower is not waiting five minutes for hot water to arrive? Is the house large enough to warrant two water heaters and two PEX water manifolds?.

Hose bibbs are ¾” to keep up with manual watering or car washing water pressure demand. For instance, the faucets are all coming off ½” connections and PEX line. Size the outgoing line of PEX coming out from the manifold accordingly.

Consider the demand on each outlet / how much water pressure desired at each outlet.

Depending on your answer, you may need to place the hose bibb PEX lines before the manifold. Is there an irrigation system in place that splits off before the manifold? You don’t want to pour salt water on your plants constantly.

Consider how you use your hose bibbs outside as well as if you plan on having a salt water system.

What size PEX manifold do you need? It depends on your two answers to the previous two points.

Just run a line to the ceiling and cap it off.* Better now while the walls are open then later when is is infinitely more difficult to expand. A list of potential endpoints are listed at the end of this post.*

Compile a list of all the hot and cold lines you want to run in this house.

The benefits of a full on manifold with only home runs are clear, but you need to determine if the initial cost is worth all the future benefits such as detecting hard to find leaks, servicing any faucet / endpoint at the your convenience (along with other advantages listed here: Advantages of a Plumbing Manifold System). First, you want to decide if you want a full home run to each faucet / outlet, or if it will be a semi-trunk and branch / manifold combination.You have one shot at doing this right the first time so let’s set you up for success! Laying out the Plan: Once you’ve determined you want to go all in on a PEX water manifold, a proper design is essential to high performing plumbing system.
