Bathroom Plumbing Diagram
The bathroom is the central plumbing hub of the CTC.
It contains the 50‑gallon fresh water tank, the 12V water pump, the cold‑water manifold, and multiple fixtures including the shower, bathroom sink, and washer/dryer combo.
This diagram provides a visual overview of how water flows through the bathroom and how grey water is routed to the under‑floor grey catch tank.
It supports the Bathroom Plumbing Plan and the Plumbing Master Diagram.
Bathroom Plumbing Overview
The bathroom manages the majority of the trailer’s water distribution and drainage.
Cold water originates here, hot water is supplied from the garage, and grey water from all bathroom fixtures drains into a combined line that feeds the under‑floor grey catch tank.
- 50‑gallon fresh water tank located in the bathroom
- 12V water pump pressurizing the cold water system
- Cold water manifold distributing water to all areas
- Hot water supply from the garage heater
- Shower, sink, and washer/dryer as primary fixtures
- Combined grey drain routed to the under‑floor grey catch tank

Key Components in the Bathroom
- Fresh Water Tank: Primary reservoir for the entire plumbing system.
- 12V Water Pump: Pressurizes cold water for all fixtures.
- Cold Water Manifold: Distributes water to bathroom, kitchen, and passenger‑side outlet.
- Shower: Hot and cold supply with dedicated drain.

Routing & Installation Notes
The bathroom plumbing routing is designed for efficiency, freeze protection, and centralized serviceability.
- Centralized distribution: All cold water originates from the bathroom.
- Short hot water run: Direct line from the garage heater.
- Combined grey drain: Simplifies routing and maintenance.
- Vent line: Prevents siphoning and improves drainage.
