Toilet Clogs - 101
When faced with rising water level in your toilet, do not flush it again! Instead, turn off the water under the tank. If there isn’t a turn-off there or you can’t turn it, remove the tank lid and lift up on the float ball or cup. Then have someone else turn the water off at the main shut off valve.
Putting your hand in a large plastic trash sack, reach into the toilet hole and try to get at the object. If this doesn’t work, use a plunger, beginning slowly and lightly and working up to a quick and forceful rhythm. If unsuccessful, try a toilet auger. Do not try using a regular plumbing snake in the toilet as it will scratch the delicate porcelain. Still no luck? Take a deep breath…and call the plumber.
