Restroom Trailer Set Up

Restroom trailer delivery should be conducted by an experienced driver who possesses the appropriate driver’s license. It’s important to note that the restroom trailer axles are equipped with electric brakes, which means the towing vehicle must have an electric brake controller.

When selecting a delivery site for the restroom trailer, ensure it is reasonably level, dry, and well-drained. Additionally, make sure there is adequate space for a pumper truck to park close to the trailer. The pumper truck will need to connect to a dump valve located at the front hitch end of the restroom trailer to remove waste from the tank. Daily access may be necessary for the pumper truck, as the restroom trailer may require pumping out on a daily basis.

Stabilizer jacks are included with some restroom trailer models but should not be used for leveling the trailer. These stabilizer jacks, also known as stab jacks, are designed to reduce bounce caused by the spring axles and rubber tires when the trailer is in a set-up position. To achieve a level position for the trailer, use blocks to lift the tires instead.

Most restroom trailers are powered by electricity, so it is recommended to provide each trailer with at least two independent electrical circuits. These circuits should be dedicated 20-amp power circuits to ensure adequate power supply. If the restroom trailer includes a winter package with electrical heaters, additional electrical power will be necessary.

It’s generally the site owner’s responsibility to supply the power cables to the trailer. Additionally, make sure that no other devices are drawing power from the circuits connected to the restroom trailer, as this can lead to insufficient power supply.

Most electrical issues in restroom trailers arise from inadequate power supply. For instance, an air conditioner might start but then trip a breaker shortly after if it does not receive sufficient electrical power. It’s essential to ensure that each power cord is appropriately sized (gauge) for both the distance it will run and the 20 amps it will draw.

Additionally, lightweight electrical cords tend to lose power over longer distances from the power source. If the power source is more than 150 feet away from the restroom trailer, it is advisable to use a generator to ensure consistent power supply.

Many restroom trailers come equipped with an on-board freshwater tank located in the mechanical room. To draw water from this tank, the water pump must be turned “on.” This setup allows the restroom trailer to use water from the tank for essential functions like toilet flushing and handwashing.

CITY WATER FUNCTION

Every restroom trailer needs a garden hose that maintains a minimum water pressure of 40 psi and a flow rate of 5 gallons per minute. The trailer features a city water connection located beneath the mechanical room, allowing for a standard ¾” garden hose to supply fresh water to the toilets and sinks.

ON BOARD FRESH WATER FUNCTION

If the restroom trailer is equipped with an on-board freshwater tank, a water pump must be activated to draw water from the tank.

WASTEWATER FUNCTION

A large waste tank is integrated into the frame of the restroom trailer, with all toilets and sinks draining directly into this tank. A 3” dump valve installed at the towing end allows a pumper truck to easily remove waste.

The restroom trailer typically features low-flush toilets that operate with a foot pedal. To use the toilet for solids, press the foot pedal halfway to fill the bowl with water. After use, press the pedal all the way down to flush the waste into the tank.

The sinks are equipped with water-conserving faucets that activate by pressing down on the top valve. These faucets automatically shut off after approximately 10 seconds, and the flow can be adjusted using a set screw beneath the valve cover (refer to the faucet manual included with the trailer).

The restroom trailer is equipped with a roof-mounted air conditioning unit that efficiently ducts air into each separate room. This system operates on 110v power and is controlled via a wall-mounted thermostat, typically located in one of the public restrooms. To prevent unauthorized adjustments, the thermostat is fitted with a lockable cover, allowing the desired temperature to be set securely. It is important to note that if electric heaters are installed in the restroom trailer, they will be regulated by separate thermostats.
