Signs Of Clogged Underground Downspout – AAA Superior Construction, NJ

Signs Your Underground Downspout Is Clogged

Underground Downspout Repair Services in New Jersey

Welcome to Superior Construction.

Gutters catch rainwater as it descends from your roof and direct its flow to your downspout to drain. Underground downspouts divert this water away from your home, which protects your foundation and keeps your basement dry. A clogged downspout can cause numerous costly structural issues. It’s important to monitor your gutters and underground downspout for signs of obstructions.

How Underground Downspouts Work

Downspouts that run into an underground system are sometimes called French drains. They typically disappear into the ground and the water travels through a pipe made of clay, plastic PVC or perforated plastic pipe. PVC is the most common material because it's smooth inside and allows debris to easily travel through. While cheaper, perforated plastic pipe holds debris in the perforations, making clogs more likely.
Water flowing through your underground system ends up in a municipal storm sewer system, a dry well or daylight. A dry well system should have an access cover for cleaning the tank and have holes so water leaches into the ground. A daylight system flows out into the open at a point lower than your home where it runs off, away from your foundation.
Just like gutters, an underground downspout system can become clogged with leaves, twigs, dirt, grit from shingles and other debris that falls on your roof. Once the downspout is clogged, rainwater is forced back through the system and can come out near your home’s foundation instead of flowing away. A clogged downspout also can cause water to back up all the way to your roof line, causing water damage to the wood beneath your shingles and the soffits.

Signs You Have A Clog

Clogged downspouts can cause serious damage to your home and its foundation. Clogs can occur in the pipe due to debris from the roof, tree roots breaching the pipe or a collapsed pipe. Look for signs like:
  • Leaking seams or joints in your gutters or downspout.
  • Water backing up and spilling over the sides of your gutters, especially after the gutters were recently cleaned.
  • Obvious blockage at the beginning or end of your underground system, especially in daylighted drains where debris can build up at the discharge area.
  • Wet soil or pooling water where your underground downspout system is buried or in your yard where water shouldn't be.
  • Signs inside your home like moisture, water stains or actual water near your downspouts and/or buried drain lines.
Place a hose into your underground system and turn the water on until you have a forceful stream. If the water sprays back toward you, it’s likely you have a clog.
