Leaking toilet tank problem
The tank is the part of your toilet system where the water flows into the bowl when you flush. If you heard some strange noises from the toilet tank with the water bill rises recently or the toilet not flush properly, unfortunately, your maybe have leaking toilets problems. Leaky toilet tank can seem relatively significant in leaking toilet system. A leaking toilet toilet not only annoy you whole day, but also waste your money. However, you can eliminate most running toilet tank problems quickly and easily.
There are some causes that make the toilet tank leaking, and they have the different symptom. Before repairing the leaking cistern tank, let’s lift the lid off your toilet tank and understand the flushing system happens in toilet tank.
When the handle was pressed, a trip lever is raised inside the tank. This lever lifts wires raise the tank ball or rubber flap at the bottom of the tank. At the bottom of the tank is the entrance of flush valve. When the flap is opened, the water in the tank rushes out past the raised tank ball and into the toilet bowl below.
While the water is rushing out of the tank, the float ball, which floats on top of the water in the tank, begins to drops down. The float ball pulls down on the float arm, raising the valve plunger in the ballcock assembly and allowing fresh water to flow into the tank. Since water seeks its own level, the water from the tank pushes the bowl water out into the drain, causing a siphoning action that cleans everything out of the bowl. When all the water is gone from the toilet bowl and air is drawn into the trap, the siphoning stops. Meanwhile, the tank ball falls back into place, closing the flush valve entrance.
As the water level continuously rises in the tank, the float ball rises until the float arm is high enough to lower the valve plunger in the ballcock assembly and shut off the incoming water. If the water fails to shut off there is an overflow tube that carries excess water down into the bowl to prevent the tank from overflowing. If water flows continuously out of the tank to the bowl and down the drain:
So we have several reasons cause a leaking toilet cistern.
- The flap could seal the flush valve securely. May reasons cause these happen. The hard water deposit sediment or an old flap, sometimes the chain links flap and lever too long or too short also make the flap can’t close the flush valve firmly.
- The piston in refill valve couldn’t seal firmly causes water continue come into tank from inlet pipe. The water continue form water supply line and flush into bowl through overflow tube.
- Third possibility is a real leak in toilet tank.
