Kitchen Systems

Kitchen Systems

The kitchen is a core functional zone of the CTC build, combining water, propane, electrical, and HVAC systems into a compact and efficient workspace.
This page documents how the kitchen’s major components—sink, refrigerator, propane stove/oven, and indoor air handler—integrate with the trailer’s plumbing, propane, and electrical systems.


1. Fresh Water Supply (Cold)

The kitchen sink receives cold water from the 50‑gallon fresh water tank located in the bathroom.
A 12V water pump pressurizes the system, sending cold water through a long PEX run from the bathroom to the kitchen.

Cold Water Considerations:

  • Longest water run in the trailer—use continuous PEX with minimal fittings.
  • Install a shutoff valve under the kitchen sink for service.
  • Sink type (TBD) may affect drain height and faucet mounting.
  • Cold water also feeds the hot water heater in the garage.

2. Hot Water Supply

Hot water is supplied from the dedicated hot water heater (planned for the garage).
Hot PEX lines run from the heater up into the bathroom and forward to the kitchen sink.

Hot Water Considerations:

  • Kitchen is the furthest fixture from the heater—insulate hot PEX lines.
  • Install a shutoff valve under the sink for hot water service.
  • Tankless heaters require a minimum flow rate—kitchen aerators may need adjustment.

3. Grey Water System (Kitchen)

The kitchen sink drains into its own dedicated grey water tank.
Originally planned as two 30‑gallon tanks, the system will be downsized to a 10–15 gallon tank since only the kitchen sink drains into it.

Grey Water Components:

  • Dedicated 10–15 gallon grey tank (under‑floor)
  • Sink P‑trap
  • Short horizontal drain run to tank inlet
  • Air admittance valve (AAV) under sink
  • Grey tank vent line
  • Hose outlet for campsite discharge

This system is completely separate from the bathroom grey water system.


4. Propane System (Stove & Oven)

The CAMPLUX 21″ Propane Range & Oven is supplied by two propane tanks mounted on the front of the trailer.
Propane lines run externally along the frame rails and enter the kitchen through a sealed, grommeted penetration.

Propane Considerations:

  • Dual‑tank setup with automatic changeover regulator.
  • Propane lines must remain outside the living space until the final entry point.
  • Install a shutoff valve behind or beside the stove.
  • Install a propane leak detector inside the kitchen.
  • Ensure proper ventilation around the stove enclosure.

5. Electrical System

The kitchen includes both 12V and 120V electrical components.
The refrigerator is the primary 12V appliance, while countertop appliances and lighting require 120V and 12V circuits.

Electrical Components:

  • RecPro 10 Cu Ft 12V Refrigerator: dedicated fused 12V circuit, heavy‑gauge wiring, rear ventilation space.
  • Stove: may require 12V or battery ignition depending on model.
  • Countertop GFCI outlet: for coffee maker, toaster, induction cooktop, etc.
  • Lighting: 12V LED overhead and optional under‑cabinet lighting.

6. HVAC Integration

The kitchen includes a Blueridge Indoor Air Handler as part of the ductless mini‑split system.
This unit provides heating and cooling for the kitchen and front living area.

Air Handler Considerations:

  • Mount high on the wall with clear airflow.
  • Ensure access for filter cleaning and maintenance.
  • Condensate drain must route downward—typically through the wall or floor.
  • Keep electrical and refrigerant line access unobstructed.

7. Space & Access Planning

The kitchen layout must accommodate the sink, refrigerator, stove, and air handler while maintaining access for plumbing, propane, and electrical service.

Key Considerations:

  • Sink: final type affects drain height and faucet mounting.
  • Refrigerator: requires ventilation space behind and above.
  • Stove: needs heat‑safe clearances and propane access.
  • Air Handler: must remain accessible for maintenance.

8. System Summary

The kitchen integrates multiple systems—water, propane, electrical, and HVAC—into a compact and efficient workspace.
Cold water is supplied from the bathroom tank, hot water from the garage heater, and grey water drains into a dedicated under‑floor tank.
Propane is supplied from dual tanks mounted on the front of the trailer, and the 12V refrigerator and air handler complete the kitchen’s core systems.

  • Cold Water: 50‑gal tank → pump → kitchen sink
  • Hot Water: heater (garage) → kitchen sink
  • Grey Water: kitchen sink → dedicated 10–15 gal tank
  • Propane: dual front tanks → regulator → stove
  • Electrical: 12V fridge, GFCI outlet, lighting
  • HVAC: Blueridge indoor air handler
