If you have a shower/bathtub and it drips when their used it's probably because of the warm high humidity it created and add the cold water in the tank will create the water on the sides. Just like a glass of water with ice in it.
You may also want to look at the connections of the water hose, or the hose itself can deteriorate, and where the rubber seals are between the tank and base, as they can deteriorate over time. And of course make sure it's not overfilling slightly.
You could do that but you would need a trap to stop sewer gas from coming in. The toilet has the trap integrated into it. If you have access to underneath then you could add one.
Many 'slow' water leaks will waste several gallons of water a day. Also, the floor around the toilet can be damaged if the leak is dripping onto the floor. Toilet repair kits are very cheap, and easy to install. Check at your local hardware store, Home Depot, or Lowe's.
If something is "dripping", then it usually means that water is coming from it slowly and intermittently. For example, if a wet towel is hung on a rail, it would be "dripping" water.
Saturated means more than it can hold so dripping wet would be saturated with water.
it coagulates.
The processes of toilet repair would depend on a few factors. They would include whether one would want to repair the tank or the seat, the type of toilet, and the issue with the toilet.
the toilet would come when you need it. The toilet would probably be no different in the future than it is today. It would be a device used to eliminate waste.
Sounds like the washing machine discharge is fitted to the main drain in the wrong place and it's discharge is filling your toilet. It's possible there may be something of a blockage just after the toilet, causing a backup. I would try to snake the the pipe from toilet out. You may even have to remove the toilet from the floor and do it there if there is no access underneath (like a basement or a crawlspace). I have snaked main drains from the toilets many times, and it's a pain having to re-re the toilet, but often it's the only way.
it would be impossible unless you had a toilet bigger than you!
it would have a crack with water dripping or spraying out of it.
my car smells like i have a petrol leak when i turn it on but have no leak underneath the car
This would depend on what brand of toilet paper it was.
