A quick orientation to the sink in your MoveMobility vehicle: how to power it, fill the freshwater tank, empty the dirty water tank, and what to check if no water comes out.

This short orientation shows how to use the handwashing sink in your vehicle. The sink runs off its own freshwater tank, with a wastewater tank underneath to catch what drains.

Key Points

  • The water pump needs power. Turn on the top red switch on the conversion power panel behind the driver's area.
  • The freshwater and grey water tanks are under the sink.
  • If you can, fill the freshwater tank in place. Unscrew the top cap, connect a hose, turn on the water and fill the tank, then disconnect the hose and close the cap.
  • Use a hose made for drinking water. A regular garden hose that's been sitting outside can affect your water quality.
  • If your hose doesn't reach the sink, take the tank out: unhook the bungee cord, unhook the blue hose from the top, and disconnect the power cord at the orange connector. Fill it at your water source, put it back, and reconnect all the hoses and power cables.
  • With the power on and the tank full, the sink works like any other sink. Lift the nozzle up before use, turn on the tap and you'll hear the pump kick in.
  • Used water drains into the dirty water tank. To empty it, remove the bungee cord, unscrew the hose from the top, dump the tank at a drain, then hook it back up to its hose and put the bungee cord back on. Empty it every day.
  • No water coming out? Check that the conversion power is on (the most common reason), that there's water in the freshwater tank, and that no fuse for the sink or water pump is broken or burnt in the rear fuse panel.
  • If you replace a fuse, use the same size and type. It's worth keeping a few spare fuses in the van.
