The item in my kit

I bought DERNORD Half-Inch Three-Way Ball Valve as part of my camper van equipment.

I bought the DERNORD valve for my water-system parts collection. Planning the tank openings before closing the interior gave me a starting point for the later routing decisions.

Where it fits my build

My Day 87 plan put the body openings ahead of the aluminum framing, flooring and wall panels. I specifically included the shower drain and the openings for three water tanks in that order of work.

I removed cargo tie-down hardware to leave mounting points for the extrusion framing, and removed door trim for the later insulation and paneling. SketchUp helped me plan how those separate jobs would fit together.

My build notes

The useful part of this diary entry is the sequence. I wanted to finish the drilling while the interior metal was bare, so later work would not mean opening finished surfaces again.

The photographs show my preceding floor-preparation session. Sweeping, washing and removing residue created the starting point for the interior work I described next.

I planned the openings and mounting access before enclosing the interior.

Alternative products

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.

Horiznext Half-Inch T-Port Valve

Horiznext Half-Inch T-Port Valve

This three-way valve has female NPT connections and a T-shaped internal passage. A lever changes the flow-routing position within the stainless-steel body.
