If you suspect that you have drain or sewer problems in your home's plumbing or the private side of your sewer lateral such as a wastewater backup, call a professionally licensed plumber for an inspection. Even if you aren't experiencing drain or sewer problems, periodic inspections by a professionally licensed plumber are a good idea. This building sewer section of your plumbing system is often neglected by homeowners until problems arise. A video inspection will show any problems including grease, roots, cracks, and offset joints that affect normal sewer flow. Simple repairs can avoid spills and save you and the District a lot of money.
