Water Pooling or Overflowing from Downspout Connection.

When underground drains are clogged, you will often see the water gushing back out of the drainage pipe and spilling out of the adapter seams. You will only be able to see this during rain, so it is important that you check your downspouts when it is raining.

If you see a water stain around your underground drain, that is also a sign that it is clogged. This will only be visible if your drain pipe is near pavement, concrete, driveway, or even a deck. More over, if the ground is swampy and over saturated close to your underground drain, that could also be a sign that it’s clogged.
