Repairing a Glacier Bay toilet depends on the problem it is experiencing, but if water is leaking on the floor under the fill valve, try to repair the problem by using a pair of pliers to turn the nut connecting the water supply to the tank an additional quarter turn. Manufacturers design supply hoses for hand tightening, but sometimes installers do not have the strength in their hands to tighten the nut sufficiently to eliminate the leak.
If the Glacier Bay toilet runs continually, try adjusting the water level. Setting the water level above this tube prevents the float from turning off the water valve, and the excess water drains down the tube.
When toilets cycle off and on continually, the problem is often with the flapper valve. Not all Glacier Bay toilets have a flapper valve, but if your unit has one, test the valve by dropping a few drops of food coloring in the tank and waiting. If the color moves to the bowl without flushing, the valve is faulty and requires replacement.
When the toilet does not flush correctly, the water level setting may be too low. Open the tank and adjust the water level to the mark on the tank wall. If this does not repair the problem, there may be a clog in the drain line.
