if you have water to the rest of the house and its the toilets only then either someone has turned off the valves under the toilets or the fill valves have both failed at the same time. [not very likely!!] cant be much of anything else.
In a toilet tank or water reservior to regulate filling.
Iron in the water would cause rusty stains in the toilet.
Why would you want to know that?HUH?!
Improper venting.
You should be able to take the old tank off and mesure the distance of the mounting bolt holes and mesure the diamiter of the water hole then go to home depot and mesure some of the tanks they have. I diagree with the previous answer. By the way, it's spelled: measure. Anyway, if you have a 1.6 gallon toilet tank, you should replace it with the same brand. Different manufacturers tanks will NOT work with just any toilet. If you have the old style toilet e.g. 3.5 to 5.0 gallon tank, you would have to find a junk dealer who would have the exact same type of tank.
i dont no but that is nasty why would you do that
My toilet is doing the same thing this morning. We had a big rain last night. Could this be part of the cause?
You probably need to replace the wax ring and possibly tighten the two bolts that hold the toilet to the floor.
I would intentionally overflow a public toilet by taking the lid off the back, then taking out the thing that covers the hole in the bottom. Then clog the toilet and just wait. The toilet will just flush and flush and flush and flush until it overflows. And then it will keep flushing. You could flood the entire bathroom with no one even knowing!
they are killer
If it is a new house, the plumbers hooked it up to the hot water supply--this actually happened to me once! Otherwise, it may be really hot outside and the water has been warmed before coming into the house.
That would be your flush valve in the tank
