What are the most common troubleshooting issues with a mobile hand washing station and how easy are they to fix on the spot?
One of the most common problems in the use of a mobile hand washing station is an electrical problem between the outlet and the unit. This can be because of a tripped breaker, an incorrectly plugged in cord or the need to reset the outlet that is located in the cabinet. More often than not, these issues are simple and easy to fix. To check that the breaker is not tripped plug in a different electrical device to the same outlet and see if it will turn on. If it does not, make sure the station is unplugged and find the breaker box. Turn on the breaker that has clicked off. Return and plug in the station.
The reset button is located between the two outlets that are positioned beside the on/off switch in the cabinet of the mobile hand washing station. It is a small button that, if it needs to be reset, will either have no light displayed or a red light. Reset and check the plug to the wall to make sure it is inserted correctly.
These simple corrections will also address the problem that caused the mobile hand washing station pump to work and then shut off. If this happens make sure that you are plugged into a dedicated 20A 110V outlet.

How is an outdoor mobile hand washing station designed to stand up to the elements? Is there anything I can do to extend the life of the cabinet if it is always outside?
An outdoor portable sink is designed to prevent damage from UV rays from the sun as well as damage due to rain, snow or sleet. The sides and back of the cabinets are either galvanized or stainless steel, making them strong and resistant to any type of mold, rust or scratching. The front of the cabinet is made of a very durable polyethylene that is resistant to UV damage caused by the sun. The top is stainless, as is the basin, making it very effective at resisting any damage caused by
the elements.
 A mobile hand washing station that is going to be used or stored outdoors also comes with an additional cover. This cover can be placed over the entire unit to prevent any long term exposure to rain, snow or sun. Protecting the surface area from this type of exposure will keep it looking new for years to come.
How can I estimate how long a fresh water tank will last?

The mobile hand washing station is designed to provide a steady and controlled stream of water that is suitable for hand washing and other uses where water is in short supply. The standard flow of water is ½ gallon per minute, which allows you to estimate how long a standard fresh water tank will last. With a standard fresh water tank of five gallons, that is filled completely, you can estimate that you have enough water for 42 hand washings. This is more than enough for a typical classroom of students per day or for several days in a smaller workplace environment. There is also the option to have additional fresh water tanks on hand so you never have to worry about running out of water.

What options are available in cabinets for mobile sinks for indoor or outdoor use?

There are several different options for mobile sinks, particularly when it comes to cabinets and tops. Indoor models may have cherry or maple or, if you want, the color of the cabinet can be customized to your specific requirements. Customized options can include virtually any color from a clinical white for a doctor's office through to a completely unique look top and cabinet designed to meet a very specific type of décor.
Sink sizes and sink shapes are also a major difference in options offered with mobile sinks. Some companies only offer a standard basin while other companies offer a huge range of different options. This can include deep basins, double or triple basins or even the position of the faucet to the back or side of the sink.

How does the water heating system work with mobile sinks? Will it add a lot to an electricity bill?
Mobile units that are designed with the consumer in mind have been built to be very easy on the electrical bill. Both the hot water heating system and the pump only activate when the taps are moved from the off to the on position. In other words, they only are drawing electricity when they are being used. The pump will begin to move the water from the fresh water tank to the sink when the cold water tap is turned on. Turning the hot water on allows the pump to also send water to the on demand heater, providing the option to use both hot and cold water at the same time.
Using a mobile sink will inevitably increase electricity consumption in your household, office, or classroom. However, when compared to the cost of plumbing, having a water heater running all the time or constantly having to move back and forth to a standard sink in the home or office it is really a time and money saver.

Are mobile sinks a practical option for a mobile catering company that actually prepares food on site?

Mobile sinks are a great option for mobile catering services, particularly those that catered events in areas without existing commercial kitchens or sources of running water and heated water. This can include halls, outdoor venues, parks and private homes. Having the ability to have immediate hot and cold running water helps with both food preparation and cooking. It also ensures that employees can follow all regulations with regards to hand washing during food preparation and handling.

Having a portable sink on sight will add to your customer's satisfaction with your service. It shows that you care about the quality of your food, the safety of your food handling practices and the level of service you provide. Since you can have multiple fresh and waste water containers on hand you never have to worry about running out of water. In addition, with a quick connect attachment, the sink can easily be attached to a potable fresh water source you can refill fresh water containers almost anywhere with a potable water supply.
