There are a number of reasons why a toilet may make noise after flushing; however, a loud noise that takes more than a minute after flushing the toilet may indicate a restricted water flow or a problem with water pressure. In such a case, the pressure valve should be adjusted while the toilet is making the noise.Know More
If the problem arises as a result of faulty float, it should be replaced. However, If the noise is produced when the toilet is refilling, there is a possibility of uneven water flow. In this case, the valve should be adjusted to reduce the rate of flow of water to the tank.
If the noise comes from the tank, the cover should be taken off and the flow of the water monitored as the tank refills. If the noise stops after the tank is refilled, it means the ballcock valve is faulty and it needs to be replaced or repaired.
However, if the noise persists even after the tank is full, the water should be monitored if it is overflowing into the vertical overflow tube located at the center of the tank. If this is the case, either the float arm should be bend slightly downwards or the ballcock mechanism should be adjusted to shut off as soon as the tank is full.Learn more about Plumbing
Flushing toilets use gravity and an increase in the height of water in the bowl when the user activates the flush valve to move water and waste through an "S-bend" into a drain pipe and out of the home. These simple devices have relatively few moving parts and, in most cases, offer many years of trouble-free service.Full Answer >
Toilets make odd noises, such as gurgles and burps, due to the movement of air through water. Most often, the air movement responsible for such noises is due to a clogged or improperly working vent stack. These clogs cause a vacuum to form as water drains. Once the force of gravity empties the water, the vacuum pulls air through the trap.Full Answer >
Repair a slow-flushing toilet due to a plugged main line by cleaning the line with a drain bladder. Locate and open the main cleanout, attach the bladder to a water hose, and insert it in the drain. Turn on the water hose to allow the bladder to work.Full Answer >
There are several reasons for poor performance of a toilet, but adjusting the water level in the tank often improves the flush. Turning the adjustment screw at the top of the valve on ball-cock valves counter-clockwise increases the water level. Adjusting concentric valves require loosening a small nut at the upper end of the adjustment rod and turning two to three full rotations before tightening the nut again.Full Answer >
