HunkerMar 27, 2019A French drain pipe can help divert water away from your home's foundation, patio or low-lying areas to help prevent damage or pooling water. The depth of the French drain depends on the purpose for using it and the location. Recommended depths can range from about 18 inches to 6 feet.
