Take Care of Your Interior Drain and It’ll Protect Your Basement

If you have a basement, water will always seek the lowest point and move in to fill empty pockets. This is where an interior drain comes in handy. It stops water from building momentum and overflowing into the interior of the basement, thereby keeping it dry.

Comprising a pipe set in a trench along the perimeter of your basement slab, the interior drain creates a sunken channel that allows water to drain out and flow along a definite path. When this component clogs, it can compromise the basement leading to water damage. Routine care and maintenance is the only way to ensure it remains functional especially during rainy weather.

Signs of a Clogged Interior Drain

You don’t need to second guess whether your interior drain has issues. A lot of the problems will manifest clearly. The easiest way to tell if your drainage isn’t functioning properly is to check the lawn or the basement. If you notice any water, chances are there’s something blocking the drain, and that’s why it’s not draining fast.

When inspecting a dysfunctional interior drain but aren’t sure of the signs, look out for these issues:

Common Interior Drain Problems

Water that seeps through the soil to your interior drain often carries sediments and can dump it into the drain. Sediments buildup gradually over time, slowing water as it flows through the ditch. Ultimately, it may block the drain. When this happens, water ceases to pass through the drain, causing the basement to flood.

If your interior drain is connected to a sump pump but it’s not draining, the problem could be a defective sump pump and not the drain. Chances are silt or soil has clogged the discharge line, and that’s why it’s not ejecting water. Ask your local plumber or contractor who installed the drain and/or sump pump to come and inspect the outlet of the discharge pipe. They will unplug the discharge pipe and detach the sump basin lid then remove soil from the mechanical parts.

As your house grows old, it may settle. This is a common problem in homes built near water or in wet climates. When soil shifts, it can cause the drainage to block, making it less efficient in moving out water. When carrying out repairs or maintenance, ask your contractor to suggest the right materials based on its age or your climate.

Interior Drain Maintenance

Routine checkups and maintenance will ensure your interior drain keeps working as it should to collect water and direct it to the sump pump system. You want to be sure it’s free of debris or anything that reduces its effectiveness. To prevent clogging, clean out and snake your drainage at least once a year. You’ll need a tough pair of gloves for this job to protect your hands as you feed the cable into your drain.

Here are the steps to snake and clean an interior drain:

1) Remove the drain’s lid or entry point.

2) Turn the snake on the cable into the drain. If the cable hits an obstruction or gets to a bend, hold it back until the snake turns in the pipe.

3) Once you’re sure it’s past the turn or obstruction, continue feeding it forward gently until it reaches the other side. Leave the snake to turn inside when it bumps into clogs and other obstacles.

4) Retract the snake and feed it right back into the device.

5) Spray water into the interior drain to push out debris or other obstacles.
