To Pitch or Not to Pitch

Posted on March 19, 2013

One of the features of an Arid Basement Waterproofing French drain system that separates us from our competition is that we pitch the PVC pipe and trench to the sump. Most companies do NOT pitch the pipe and only go to a uniform depth of about 6 to 8 inches. These companies, in their literature, will state something regarding the footing (e.g., to the footing, alongside the footing). The reason for creating a downward slope to the pit is so the water is gravity-fed down to the sump and pumped out. In addition, that flowing water constantly cleans out the pipe because water doesn't sit in a tilted pipe. Creating a pitched trench clearly takes more labor, removing and replacing material, and know-how, including how to navigate the pitch around sewer pipes, boulders, etc. Some customers ask why there are companies out there who don't pitch the pipe. It's because it's simpler: less dirt is removed so less gravel is needed. But potentially system-blocking sedimentation can occur when water sits in a flat, non-pitched pipe.
