Q: How do the sinks work?

A: The sink basin itself is set in a cabinet that contains a fresh water tank and a waste water tank.  Most products are electric powered and contain a pump and a hot water heater inside the cabinet.  Move the sink to the desired location, fill the fresh water tank and plug it in to a standard outlet.  If there is no access to electricity, sinks can be configured with either a battery pack, a propane gas power source or a foot pump (cold water only). Please contact us about ordering a sink without electricity if you do not see what you'd like listed on our site. 

Q: How easy is it to move the sink?

A: All cabinets are set on casters that allow the sinks to be easily moved.  The casters will lock in place to prevent inadvertent moving.

Q: How deep are the sink basins?

A: The standard depth is 6”, however, many models have a 10” basin.  In some cases, we can special order a 10" basin.  Please contact us if you have this requirement.

Q: How do you know when you have to dump the waste tank?

A: The waste water tank generally holds one gallon more than the fresh water tank.  When you need to refill the fresh water tank, it's time to empty the waste water tank.

Q: How many hand washings can you get from a filled fresh water container?

A: You can get approximately 40-50 fifteen second hand washings per tank of fresh water.

Q: What is the hot water temperature?

A:  The temperature of warm and hot water sinks varies somewhat by manufacturer, but generally ranges between 110 and 140 degrees.  Temperature can be adjusted in some models.  Mixing hot and cold water through the faucet, as in any sink, allows for modification as well. A few units only heat water a certain level above room tempurature so be sure to read the specs on your warm/hot water sink to be sure. 

Q:  Are portable sinks difficult to install and use? 

A: No, they are extremely easy to install and use.  The sinks are self-contained and are on casters for easy mobility.  The pump and hot water heater are located inside the cabinet, along with fresh and waste water tanks.  Just roll the sink to the desired location, fill the fresh water tank and plug in to any 110 Volt, 20 AMP US standard electrical outlet and switch the pump/heater on.   Note that some sinks are cold water only and operate by either a hand pump or a foot pump.  Some models can be operated by battery or propane power. 

Q: How do I empty and refill the water tanks?

 A: Simply open the cabinet doors and remove the tanks.  Fill the fresh water tank from a tap or hose.  Empty the waste water tank in an appropriate drain.  Fill and roll kits are available to make transporting the tanks easier. 

Q: How do I clean the sink?

A: Clean the sink with non-abrasive cleaners and a soft cloth.  Use a Steramine quaternary sanitizer to clean the drain and hot water system. 

Q: Are there regulatory restrictions in using portable sinks?

A: Some municipalities and localities have guidelines or restrictions on the use of a portable sink in lieu of a plumbed sink.  Please check with your local authorities if there is any question as to the permissibility before purchasing as it is difficult and expensive to return a sink.
