An underground gutter drain is a crucial part of your home's drainage system. When it becomes clogged, water can back up, leading to foundation problems, landscaping damage, and even basement flooding. This article will guide you through the process of unclogging your underground gutter drain, from identifying the problem to choosing the right solution.

Identifying the Problem: Signs of a Clogged Underground Gutter Drain

Before you start digging, it's important to confirm you have a clogged drain and not another drainage issue. Here are some key signs:

• Puddles or standing water: Water pooling around your foundation or near downspouts is a major red flag.
• Slow draining gutters: Gutters draining slowly or not at all indicate a blockage somewhere in the system.
• Soggy soil: Noticeably damp or saturated soil around the downspouts suggests water isn't draining properly.
• Basement flooding: In severe cases, a blocked underground drain can lead to basement flooding, especially during heavy rain.

If you're experiencing any of these problems, it's time to investigate further.

Tools and Materials You'll Need

Before you begin, gather these essential tools and materials:

• Garden hose: To help locate the clog.
• Wet/dry vacuum: For removing standing water and debris.
• Plumbing snake (flexible auger): To break up and remove clogs. Choose one long enough to reach the suspected clog location.
• Shovel: For digging access to the drain.
• Gloves: To protect your hands.
• Safety glasses: To protect your eyes.
• Drain cleaner (optional): Chemical drain cleaners can be effective, but use them cautiously and according to the manufacturer's instructions. They can harm pipes and the environment if misused.
• Bucket: For collecting debris and water.
• Camera Inspection System (optional, but recommended): This can help pinpoint the location and cause of the blockage.

Locating the Clog: Step-by-Step Instructions

1. Inspect your gutters and downspouts: Look for visible debris that could be contributing to the clog. Clear any leaves, twigs, or other obstructions you find.
2. Use a garden hose: Run water down your gutters. Observe where the water pools or flows slowly. This will help you pinpoint the general location of the blockage.
3. Check for access points: Look for cleanouts or access points along your drain line. These are usually capped openings that allow access to the pipe.
4. Consider a camera inspection: If you can't easily locate the clog, a plumbing camera inspection system can be incredibly helpful. This allows you to visually examine the pipe and see the exact location and nature of the clog.

Methods for Clearing the Clog

Once you've located the clog, you can use one of these methods to clear it:

1. Using a Plumbing Snake (Auger):

• Access the drain: Carefully dig around the suspected clog location to expose a section of the drain pipe.
• Insert the snake: Feed the snake into the drain pipe, rotating it as you push it forward.
• Break up the clog: Feel for resistance. Once you encounter the clog, continue rotating and pushing the snake to break up the blockage.
• Remove the clog: Slowly pull the snake back out, removing the debris that it has collected.
• Flush with water: Run water through the drain to ensure it is now flowing freely.

2. Using a Wet/Dry Vacuum:

• Remove standing water: Use the wet/dry vacuum to remove any standing water around the drain.
• Suck out debris: If there's loose debris in the drain opening, try using the vacuum to suck it out. This may only be effective for minor clogs.

3. Chemical Drain Cleaners (Use with Caution!):

• Follow instructions carefully: Always read and follow the manufacturer's instructions precisely. Wear appropriate safety gear.
• Pour the cleaner into the drain: Pour the appropriate amount of drain cleaner into the drain.
• Wait: Allow the cleaner to work for the recommended time.
• Flush with water: After the waiting period, flush the drain with plenty of water.

4. Hydro Jetting (Professional Service):

For stubborn clogs or if you lack the tools or experience, consider calling a professional plumber. They can use hydro jetting, a high-pressure water jet to blast away even the most stubborn blockages.

Prevention is Key: Maintaining Your Underground Gutter Drain

Regular maintenance can prevent future clogs and save you from costly repairs. Here's what you can do:

• Clean your gutters regularly: Remove leaves, debris, and other obstructions from your gutters at least twice a year.
• Install gutter guards: These can significantly reduce the amount of debris that enters your gutters.
• Inspect your downspouts: Make sure they are free of obstructions and securely attached.
• Schedule professional drain cleaning: Consider having a plumber professionally clean your drain lines every few years, especially if you have trees nearby.

By following these steps and incorporating regular maintenance, you can keep your underground gutter drain flowing smoothly and prevent costly problems down the road. Remember, safety first! If you're unsure about any step, it's best to call a professional plumber.
