Lift the lid off of the tank and set it aside on a flat, stable surface. You’ll now have access to the flushing mechanisms inside the tank. Be careful not to drop the lid or set it somewhere from which it might fall. Toilet tank lids are made of ceramic and can break fairly easily. The water in the tank should rest 1–2 inches (2.5–5.1 cm) below the fill valve and overflow tube (the large open pipe near the center of the tank). If it seems higher or lower than this level, your water level may be off-balance. Your toilet may also have a line in its tank, either printed on or etched in porcelain, that shows you where the water level should be. Locate the external water valve on the wall behind and beneath the toilet. Rotate the oblong knob clockwise as far as it will go, then flush the toilet. After it flushes, the tank will not refill itself. This will allow you to work inside the tank unobstructed.  Keep turning the knob until you hear the water stop running. Do not attempt to adjust or repair any of the mechanisms inside the toilet tank without emptying it first. Look over the flushing mechanisms to see what kind of condition they’re in. If you notice any obvious damage or defects, you might need to call a professional to have the part repaired. Check the toilet tank’s float, a plastic ball attached to a long arm at the top of the fill valve. The height of the float determines how much water remains in the tank after it refills. It should be at the water level if it is not broken. If the float appears too high or low, adjust the float height and when you refill the tank, check how it changes the water level.  If it is above or below the water level, this may be the source of your high/low water level. Give the float a shake. If you can hear water inside of it, you should have a plumber replace it. Make sure the float is properly connected to the fill valve. Directly on top of the fill valve should be a single screw. Turn this screw clockwise or counterclockwise 1 full rotation. Clockwise will raise the water level and counterclockwise will lower it.  Avoid turning the screw more than 1 full rotation at a time. Doing too large of an adjustment at once could cause the toilet to flush inconsistently. If the screw is too rusty to turn, you can adjust the float by simply turning it. It is threaded to the metal rod the connects directly to the fill valve. Turn the water to the toilet back on and give the tank a minute or 2 to fill up. After you’ve flushed the toilet, observe the water level in the bowl. Ideally, the bowl should be about halfway full. If the water in the bowl still looks too high or low, empty the tank and try adjusting the float again until you get it right. Call a plumber if the water level is still off after adjusting the float several times.
