A clogged drain can emit an unpleasant smell, which may indicate a blockage needs to be cleared.

If water starts draining slowly or not at all, it's likely there is a blockage in the drain pipe.

Clogs can cause air pressure to build up in the drain system or sewer line, leading to gurgling noises coming from the drain when running water or flushing the toilet.

If you have multiple drains that are clogged, it can cause water to back up and overflow out of the sink or tub.

If moisture can't escape through the pipes due to a clog, over time, mold or mildew can start growing near your sink and other areas with plumbing fixtures.

For a natural and effective way to break up blockages, try pouring hot water down the drain, followed by one cup of bicarbonate of soda and a cup of vinegar. Leave the mixture for ten minutes, then flush with more hot water. This combination should help get your drains flowing freely again.

If you have a blocked drain, there are two ways to help get your pipes flowing freely again. One is drain snaking, which is the simplest method to clear a blocked drain. The other is hydro-jetting, which is an aggressive process used when a drain snake isn't enough to unclog the pipe.

A plumber's snake is the best choice for removing major clogs or deep-down blockages, although it is more invasive and time-consuming than a chemical cleaner. Using a snake can also be quite dirty, but it will be the most effective method.

The time it takes for a plumber to unblock a drain depends on the severity of the blockage. Typically, simple drainage problems can be resolved within an hour or two, while more complex problems, such as those that require camera inspection, may take longer.

Leaving a drain clogged for too long can cause serious problems, such as causing backups in the plumbing system and allowing dangerous bacteria to accumulate. It may also lead to costly drain pipe repair if left unresolved.
