Repair Sewer System
Unfortunately, it takes a couple years to realize if you have hired a plumber that does not pay attention to detail and or just provides cheap work. When the plumber is connecting the PVC joints together, if care is not taken to make sure the joints are dry and clean, the joint will not seal properly.
Also, a good primer and glue should be used. Furthermore, after sticking the pipe into the fitting, a quarter turn should need to be made. All sounds easy enough, but as we know, not all people take pride in what they do. As shown here, a glue joint became unsealed allowing for roots to enter. This particular error costs this customer a couple hundred dollars. Hire a quality plumber the first time like Mock Plumbing Repairs in Sugar Land.
