Flushometer type needs at least 30 PSI to operate semi decently 50 PSI or more would be ideal
On the inner rim of your toilet where the water flushes out from the cistern, if these small holes are blocked it wont make the right angled pressure to flush a toilet
Sink is not vented properly and the water from the p-trap under the sink COULD be sucked out by the hydrostatic pressure from the toilet flushing.
pull the toilet. Make sure the trap is clear on the toilet, and then snake the toilet line.
Shove the plunger into the toilet and go to town. The key is to get a seal between the plunger and the toilet bowl around the exit area. This is what will hopefully allow you to 'move' the water and shift whatever is blocking the pipes. It helps to have enough "water" in the toilet to cover the plunger base. This may involve taking the scary risk of flushing the toilet, but without enough liquid in the toilet, you're apt to make a big splash.
Of course
the turds make pressure on the water like an explosion
A bidet toilet offers features such as a water spray for cleaning, adjustable water temperature and pressure, and a drying function, which are not typically found in a traditional toilet.
When it's windy, the air pressure outside your home changes, causing the air pressure inside the plumbing system to also change. This change in pressure can make the water in your toilet bowl move or ripple.

The toilet may randomly make noise due to a faulty flapper valve, a loose fill valve, or a problem with the water pressure in the pipes. These issues can cause the toilet to run intermittently, leading to noise.
Sink is not vented properly and the water from the p-trap under the sink COULD be sucked out by the hydrostatic pressure from the toilet flushing.
Your toilet makes noise when flushing because of the water flowing through the pipes and the movement of the flushing mechanism. The noise is normal and is a result of the water pressure and air being pushed through the system.
Unfortunately, yes, it does. The water holds all the bacteria from all the buissness that people make on your toilet. So it is better to close the toilet seat when you flush!
When you flush your toilet, the loud noise may be caused by a problem with the water pressure, a malfunctioning fill valve, or a loose or damaged component in the toilet's mechanism. It is important to have a plumber inspect and repair the issue to prevent further damage.
My g/f has this happen to her regularly and, it was only when I asked that she said she usually flushes once to get the flush working and then immediately after to make certain the toilet flushes everything away. She said that if a toilet has good pressure, it will often splash out when she flushes.
To lower the toilet water level, you can adjust the float valve in the toilet tank. This can usually be done by turning the adjustment screw on the float valve. Make sure to flush the toilet after making the adjustment to check the water level.
