The toilet and the sink both drain into the grey water waste lines. Because they are connected by piping, sound can travel through the pipes from the toilet to the sink.

PVC was used instead of cast iron or the pipe is against the back of the wall so the sound is transferred through the wall.

What could a dribbling noise be that you hear from the main floor ceiling after flushing the toilet or during the shower if there is no sign of water leakage under the toilet or shower?

If the toilet and shower are in an upper floor then there is a PVC drain for both that will drain to either the sewer or septic. If there is a vertical piece to this, as there is in my basement, then you actually get some dribbling and running sounds from the water 'falling' down that vertical PVC. I get this same noise from the washing machine on the main floor draining down to the basement.


How do you eliminate the noise if the sound of the water running is extremely loud when the toilet bowl fills?

If the toilet is continuously running, you need to replace the flush valve assembly, or part of it, in the tank. If the flushing sound itself bothers you, you might be able to buy styrofoam insulation to line the inside of the tank. This will reduce the noise a bit while the tank is refilling, and will also reduce condensation on the outside of the tank during humid weather. Consider also replacing the toilet with a newer low-flush type. These flush quickly, refill quickly and use considerably less water, and are often quieter in operation than old-style toilets.


When water drains out of the shower bathtub why do you hear a really loud ping ping ping noise in the wall across from the shower bathtub as it goes down the drain fast at first slower as it empties?

You are probably hearing the hot water hitting the cold pipe which causes expansion thus the pinging sound. Drain speed could probably be clogged vent stacks try cleaning them out.


Why does gurgles noise come from bathtub when commode is flushed?

In order for water to flow down a pipe, there must be a vent to allow the air to escape. Above a toilet, on the roof, there is usually a pipe or a vent hood, which is connected to the drain pipe. When the toilet is flushed, the sound of water draining can be heard issuing from this vent. In addition to the above answer, the air rushing through the water may be the cause of the gurgling sound, which is the air escaping through the vent to prevent the build up of air pressure inside your water system.
