Flow-Path Choices Within the Water Layout
I used SketchUp to plan the interior and put body openings ahead of the framing, floor and wall panels.
My Interior Preparation notes included the shower drain and openings for three water tanks in that preparation sequence.
I removed cargo tie-down hardware for later framing mounts and door trim for the later insulation and paneling.

My Takeaway for the Build
Planning openings for three tanks made the route between connections part of the interior design. My DERNORD purchase uses a T-port valve. Horiznext retains that passage arrangement, while the L-port alternative connects the ports differently; the internal path is therefore a more useful comparison than the similar-looking lever and body.

DERNORD
Connections
1/2-inch female NPT
Port
T-port, three-way
The DERNORD three-way valve has half-inch female NPT connections and a T-port arrangement. Its multiple ports make flow routing different from a simple two-ended shutoff valve. For a van water-layout drawing, label the ports and intended handle positions before choosing the connection route. Keep that drawing with the valve so later maintenance can identify which path each position selects.
It has three connections and a different internal passage arrangement. Identify the required flow paths and documented handle positions for the actual valve.

Two Alternatives to Compare
Horiznext also uses a T-port arrangement. The second alternative uses an L-port, which selects between flow paths differently and changes the routing possibilities.
