if the wind blows when it rains, it could suck the water out of the trap
Water runs in the toilet bowl to maintain proper water levels and to flush waste down the drain when the toilet is flushed.
The water in the lower toilet is probably being siphoned out of the tank by the negative pressure caused by flushing the upper toilet. This CAN happen if the water level in the tank of the lower toilet is over the top of the ballcock. If this is the case, the tank water is being siphoned into your drinking water! Replace the ballcock with a Fluidmaster right away. If you have a small white fill valve that sits in the bottom of the tank, get rid of it. These are illegal and WILL siphon under these conditions. If the lower toilet runs AFTER the fill cycle of the upper toilet, it may be that the ballcock seals at a lower pressure, and the pressure spike when the upper toilet shuts off causes it to run a bit until the added water closes the valve a little tighter.
A toilet may run randomly due to a faulty flapper valve, a leak in the fill valve, or a problem with the float. These issues can cause water to continuously flow into the toilet bowl, leading to a running toilet.
Your toilet may run occasionally due to a faulty flapper valve, a problem with the fill valve, or a leak in the tank. These issues can cause water to continuously flow into the bowl, leading to the sound of running water. It is important to address these problems promptly to prevent water waste and potential damage to your toilet.

Your toilet may be running intermittently due to a faulty flapper valve, a problem with the fill valve, or a leak in the tank. These issues can cause water to continuously leak from the tank into the bowl, triggering the toilet to run on and off. It is important to address these problems promptly to prevent water waste and potential damage to your toilet.
Your toilet may run intermittently due to a faulty flapper valve, a problem with the fill valve, or a leak in the tank. These issues can cause water to continuously leak from the tank to the bowl, leading to the intermittent running of the toilet.
Your toilet may run periodically due to a faulty flapper valve, a problem with the fill valve, or a leak in the tank. These issues can cause water to continuously leak from the tank to the bowl, leading to the periodic running of the toilet.
Usually caused by drop in toilet bowl cleaners. They also eat away the rubber flappers
A continuously running toilet is usually caused by a faulty flapper valve or a problem with the fill valve. The flapper valve may not be sealing properly, allowing water to continuously leak into the bowl. The fill valve may be malfunctioning, causing the tank to constantly refill. Both issues can lead to a running toilet.
After flushing, a toilet may run for a few seconds due to a faulty flapper valve or a problem with the fill valve. This can cause water to continue flowing into the tank, leading to the running sound. It is important to address this issue promptly to prevent water waste and potential damage to the toilet.
Probably the drain. Dry it off with paper towels and then run some water through it. Start at the trap and use a piece of toilet paper that will show the slightest trace of moisture. If you find it at the trap, work your way up at each connection until it remains dry. That will tell you where the leak is. Could be at the bottom of the sink. Added:: You should also check the water supply lines that run up to the sink in the same manor as above using a piece of toilet paper...Because a water line can still be leaking without actually dripping water especially in vertical lines,you could also have water seeping from around a fitting and slowly running down the pipe to the bottom of the cabinet
