RV Tips - Utilities

Managing utilities is a critical part of RV life, whether you are at a full-hookup campsite or boondocking off-grid. Understanding and maintaining your RV's utility systems will ensure a comfortable and hassle-free experience.

Water System

The RV water system includes a freshwater tank, a water heater, a pump, and a network of pipes and faucets.

Hooking Up to City Water

When connecting to an external water source, always use a Potable Water Hose and a Water Pressure Regulator. Excessive pressure can damage your RV's plumbing.

Potable Water Hose

Safe transfer of drinking water

ONLY use white or blue hoses labeled as potable

Water Pressure Regulator

Protects RV plumbing from high pressure

Essential for all city water connections

Water Filter

Managing the Freshwater Tank

If you are not hooked up to city water, you will rely on your RV's freshwater tank and a 12V water pump.


Electrical System

The electrical system powers your lights, appliances, and charges your batteries. It typically involves shore power, a converter/inverter, and batteries.

Shore Power Connection

Always check the power pedestal with a voltmeter or a dedicated Surge Protector before plugging in your RV. This protects your electronics from faulty wiring or power spikes.


Batteries and Inverter

RV batteries (usually deep cycle) power the 12V system (lights, pump, furnace fan) when shore power is unavailable. The inverter converts 12V DC power to 120V AC power for household outlets.

Dumping Procedure
  1. Wear gloves and connect a sewer hose from the RV outlet to the dump station or sewer connection.
  2. Open the Black Tank Valve first.
  3. Once the black tank is empty, close the black tank valve.
  4. Open the Gray Tank Valve to clean the hose.
  5. Close the gray tank valve, disconnect the hose, and rinse the hose. Store the hose in a designated sealed area.

Propane (LP Gas)

Propane is used to power the refrigerator, water heater, furnace, and cooktop.
