French Drains FAQs, answered by experts

The best drain cleaners are biodegradable ones or a mixture of baking soda and vinegar. Strong, caustic chemicals may seem appealing with promises of unclogging your drain quickly, but liquid drain cleaners can cause damage to your pipes over time. Consider making your own drain cleaner with baking soda and vinegar.

Keep your egress window from flooding by ensuring that the drainage system in the window well is clear and in good working condition. Inspect the window well every few months to remove any blockages and test the drainage system. It’s better to discover potential problems before your window well fills with water during heavy rain.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

Professionals use snakes, hydrojetting, or chemical cleaners to clear blockages effectively without damaging pipes.

It is generally not recommended to pour hot or boiling water down a drain to unfreeze pipes due to significant risks. In some cases, the sudden temperature change can cause more ice buildup or produce steam, which increases pressure and could cause the pipe to burst, leading to costly damage and potential burn injuries. While hot water might help with a partially frozen drainpipe, it is unlikely to thaw a completely blocked water pipe further down the system. Additionally, boiling water can damage plastic pipes over time. Safer and more effective methods include using a space heater near the frozen section or applying hot towels directly to the pipe.
