There's a leak in the pipe.
because there is a Dukie stuck in the bottom of the toilet so you have to take out your toilet and flush the system.
Because the passageways in the toilet that carry the water from the tank to the bowl are, umm, 'full of air' (for lack of a better term). The water rushes from the tank into the bowl to flush, but all the air is in the way, so you see some come out of the siphon. That's as simple as I can make it.
30" milk snake Answer is.... Erm Yes. But only on flush 2
Yes you can put it down the toilet, as long as you flush it. And no it's very unlikely to come back alive.
Your ballcock is comming on -- replace tank ball or sometimes you have to change out flush valve -- but change tank ball first and see if that will do it You hardly ever have to change flush valve -- Your ballcock is what lets water come into your tank
Your water lines aren't properly isolated. when you flush the toilet and your water lines are refilling with water it can create water hammer. This is usually worse if your water pipes are either not properly supported or come in contact with wood joists or studs. You may also have very high water pressure which means a lot of air comes through with the water, try closing the water inlet a little. A loose washer on the shut off valve for the toilet can cause the jackhammer sound you describe.
If it is full, you can't put more in it, full is full. Flush the toilet, it is going to come up in the shower. == == == == == ==
Go to the toilet, flush it 3 times and come back.
It comes from the Reservoir.
If your plunger is left in the bowl. :) Since I've been snaking out toilets for many years I come to the conclusion that when a toilet doesn't flush right, the reason is like lightening and it never strikes the same reason twice. So your problem of your toilet not flushing smooth can be a million different problems but 90% of those problems are in the toilet bowl trap. If you plunge and snake the toilet and it still wont flush right then pull the toilet and look at the drain and if its clear then your problem is still the toilet which since china makes stuff so cheap , its almost cheaper to buy a new toilet then to buy the repair kit for your old one, in fact to have me repair your toilet and to have me install a new toilet with buying the toilet would be about the same price so almost everyone gets a new toilet and we live happily ever after.
I am assuming you mean the flush toilet bowl. This is not as easy to answer as one might think. I would love to say, "1889," however this would be totally off the mark. Click on the related links section (Wikipedia) indicated below for a surprising history of the flush toilet. Excuse me, but I have to go the the rest room.
Take the lid off of the back of the toilet and there will be a hole with water draing out. Above the hole there will be a plug that is attached to the flusing handle on the outside of the tank. Push the plug down into the hole (don't worry its clean water) and it should seal the hole and no more water will come out.
