Signs of a Developing Drain Clog
It’s tempting to ignore a slow drain or occasional gurgling sound, but those minor issues can quickly become serious plumbing headaches. Being proactive can save you from water damage and costly repairs.
Common symptoms include:
- Slow-draining sinks, showers, or tubs. If the water pools instead of draining quickly, buildup in the pipes might be to blame.
- Unpleasant odors coming from drains. Food particles, grease, and organic material trapped in your pipes can lead to persistent bad smells.
- Frequent clogs. Recurrent clogs point to a larger obstruction or buildup somewhere deeper in your system.
- Gurgling sounds. If you hear bubbling when water drains, air could be trapped by a blockage.
- Water backups. Seeing water come up in unexpected places, like a sink when you flush the toilet, signals a more serious clog.
Don’t wait for these issues to escalate. Allen Service delivers efficient, same-day services to help fix the problem before it gets worse.

How Denver’s Water Quality Affects Your Drains
Living in Denver means dealing with hard water, which contains high levels of minerals like calcium and magnesium. Over time, these minerals can build up inside your pipes, contributing to clogs and reducing water flow. Hard water also interacts with soap, leading to the formation of soap scum. This scum can attach to hair and other debris, creating dense blockages that are tough to remove.
At Allen Service, our technicians are trained to address the unique challenges of Denver’s water quality. We use advanced equipment and techniques to clear hard water deposits and prevent future buildup, keeping your drains flowing freely and your plumbing system in top condition.
What Substances Cause Drain Clogs?
Knowing what causes clogs can help you prevent them in the future. While some blockages are unavoidable, most are caused by everyday substances going down your drains.
Common causes of drain clogs include:
- Grease and oil. These substances harden when they cool, sticking to the inner walls of your pipes and narrowing the flow.
- Food scraps. Certain foods, like pasta, rice, and potato peels, expand with water and can get trapped in pipes.
- Hair. This is a major clog contributor in bathroom drains, catching soap scum and creating tough tangles.
- Soap residue. Traditional bar soaps can leave behind a sticky film that accumulates over time.
- Non-flushable items. Paper towels, wet wipes, and similar items don't break down like toilet paper and can cause blockages.
By being mindful of what enters your drain, you can extend the life of your plumbing and avoid frequent clogs.

DIY Drain Maintenance Tips
While professional drain cleaning is essential for long-term plumbing health, you can take steps to maintain your drains between visits.
Our drain cleaning professionals recommend simple steps like:
- Using a drain strainer. Install strainers in your sinks and showers to catch food particles, hair, and debris before they enter the drain.
- Running hot water. Pour hot (not boiling) water down your sink after washing dishes to help dissolve grease and wash away debris.
- Avoiding liquid drain cleaners. These harsh chemicals can damage your pipes over time and may not fully clear tough clogs.
- Cleaning your sink and tub stoppers. Remove and clean stoppers regularly to get rid of trapped hair and soap scum.
- Using vinegar and baking soda. Every few weeks, pour a cup of baking soda followed by a cup of vinegar down your drain, wait 15 minutes, and flush with hot water. This natural solution is great for light maintenance.
Even with these preventative measures, clogs can still happen. When they do, trust Allen Service to provide professional solutions that address the root of your drain problems.
