City Water Inlets in RVs
A city water inlet is a crucial connection point on your RV’s exterior that allows you to hook up to an external pressurized water source, such as a hose bib at a campground or RV park. This provides running water to your RV’s plumbing system for showers, sinks, and faucets without relying on your onboard fresh tank water supply.
Types of City Water Inlets:

Standalone City Water Inlet:
This is a single connection point specifically for the city water hose. It typically includes a shut-off valve to control water flow and a pressure regulator to prevent damage to your RV's plumbing system from excessively high water pressure.

Combo City Water Fill and Fresh Tank Fill:
This combines the city water inlet with a connection for filling your fresh tank. A diverter valve allows you to choose whether incoming water fills the fresh tank or goes directly into the plumbing system.

Panels with Shared Inlet and Diverter:
Some panels incorporate a city water inlet as part of a larger panel that may also include a faucet, showerhead, and soap dispenser. These offer a streamlined and aesthetically pleasing option with a diverter valve to select between filling the fresh tank or supplying the RV's plumbing.
