The answer to 'why is my pipe making gurgling noise' is that the gurgling sound is typically caused by a blocked or partially blocked drain pipe. This can happen when debris, hair, or other materials accumulate in the pipe, creating an obstruction that traps air and causes the gurgling sound when water flows through.
Some common symptoms of a gurgling pipe include the gurgling noise, slow draining sinks or tubs, and sometimes unpleasant odors coming from the drain. The good news is that this is often a relatively simple problem to fix, either through DIY drain cleaning or with the help of a professional plumber.
