Determine at what level the float valve will need to be installed to maintain the water level you desire in either in your tank or sump. Locate the float valve carefully, make sure that the float will be able to move freely and will not interfere with any other equipment.
You will probably need to remove some of the water from the sump if you are going to install the float valve through it. Drill the appropriate sized hole in the sump wall and install the float valve. Trim the excess tubing and connect the plastic tubing to the float valve. Check the float valve movement.
