Partially clogged main drain or the little holes you see under the rim may be stopped up. Another possibility which is rare but can happen is the vent pipe can become plugged.

Water pressure surges when flushing toilet?

There are a variety of possible reasons that would cause water not to go down when flushed. The most common reasons are (1) an object has been accidently (or spitefully!) flushed in a previous flush and lodged within the toilet or the drain pipe. (2) Build up has formed in the toilet line so that the normal contents plug the line temporarily. Solutions: mechanical snake. If necessary remove toilet. Prevention: (1) None known (2) Treat toilet line with microbial build-up remover product periodically.


Why would your bathroom shower begin to flood everytime you use your upstairs shower or sink?

The shower drain and waste lines on up to the other fixtures located above need to be clear so that water will flow. Just downhill of the shower drain there is probably a blockage in the waste pipe. The blockage could cause slow draining. If it is completely blocked, the shower pan will not drain back out over time. You will need to run a plumbers snake down the line below the shower drain. If the toilet in the same room as the shower when flushed also shows water coming into the shower drain, it will be best to take up the toilet off the base and run a plumbers snake from that point. Warning for very slow draining lines or lines that do not drain, DO NOT use Drain cleaning chemicals. Good luck and you may wish to call rotorooter.

How do you get water out of a toilet before removing it?

I will usually pick the toilet straight up and set it in the tub if there is one. Put a towel in first to protect the tub finish and then tip it front to back several times to cause the water to come out. You can set the toilet into a pan big enough to hold the bottom and then carry it outside or rock in in the pan. There is only about a gallon at most in the base of the toilet after you have flushed it.
