Problems and Solutions
Problems with tubing and connectors
1. When the connections of tubes are leaking, you should check the tubes to make sure they are fully plugged into the connectors-- the tube can not be easily pulled out if it is fully inserted. To ensure no leaking, you need to verify each connection is robust before beginning the experiment. If there is a leak at the top of the settling column, stop any experiment and drain the column. You may need to remove the turbidimeter to adjust the connection.
Problems with apparatus
1. If the apparatus is not on when you turn on the switch, that is because the power strip sometimes trips the GFI protection. When you meet this problem, press the GFI reset button which is on the outlet behind the water tank.
2. If raw water pump is not running at loading state, check the direction of flow at that pump (should be towards the rapid mix) and the mode (should be on mA).
