The arm controls the Flush Valve. Inside the flush valve is a black rubber "seal" that closes the end of the fill pipe and stops the water. If a piece of sand, grit, or small rock gets imbedded in the seal it will allow water to pass through even when the tank is full. Either you take apart the flush valve and remove the grit, or you replace the whole valve. Sometimes even when the grit is removed the rubber seal is damaged and must be replaced. A new valve, and some of these replacement seals can be purchased at a good hardware or plumbing supply store. Use the valve handle, below the tank, on the pipe that comes through the wall, to turn off the water before replacing the seal or valve.

how do i adjust the water level in the toilet tank?


Lift the top lid of the toilet tank. You will ball valve assembly. At the end of the arm of the ball valve there is a nut which if tightened lifts the ball valve. If loosened the ball valve goes down. You can adjust it to suit your requirement.

toilet flushes fine but when the tank has filled it seems like the float ball keeps bobbing up and down letting more water or air into the tank. it will do this 5/6 times then quits. its almost like it is burping.


The ball float follows the tank water level, and repeated cycles of the float dropping and opening the fill valve would likely reflect a leak in the flush valve. You could try adjusting the float arm downward so that it will respond to a lower water level. Try turning off the supply valve, flushing it and listen for water leaking past the flush valve after it closes. If it does, replace the flapper or adjust the chain.
