French Drains questions, answered by experts

The best practice is to hydro jet your sewer line once per year. However, there are several factors that can affect this recommendation, including the age and condition of your pipes, how often your sewer line is used, and the type of waste disposed of in the system. When in doubt, ask a licensed plumber for their recommendation for your plumbing system. 

Anything you drop down your sink runs the risk of damaging and clogging your pipes. Hair, bits of food, and other debris can catch on the item and build up over time, causing a clog. Even if it’s not valuable, it’s definitely worth trying to retrieve the item, or at the very least, asking a pro for specific advice.

French drains may fail when they become clogged with soil granules that slip through the pores of the landscaping fabric and through the holes in the pipe. 

Over time, this debris can build up inside the pipe and prevent water flow. To prevent this failure from happening, regularly flush out your French drain and keep debris away from the inlet grate.

Professional plumbers use many high-grade chemicals to unclog drains. Many use hydrochloric acid, known as muriatic acid, when it comes to extreme blockages. 

While you don’t have to run out and immediately buy a new toilet at the first sign of a clog, if the toilet keeps clogging because it’s a low-flow or poorly designed model, a new toilet may be the way to go. If your toilet keeps clogging, you can try using less toilet paper, adjusting the fill valve, checking the toilet vent pipe on the roof, and using a toilet auger to make sure nothing is stuck in the pipe or trap.
