How do I know my water line is leaking? Sometimes the signs are obvious such as water coming up in your yard, street or basement but a slow leak can be detected often times by pressing your ear to the pipe near your water meter. If a leak is present you will hear a hissing noise.
How do I know my sewer line is cracked? This can only be detected by televising your sewer. Cracks in sewer pipes are usually caused by roots.
How do I know the sewer line is plugged and not just the small drain under the basement floor? If your main sewer is plugged due to roots or a collapsed pipe you will get a backup, usually in your floor drain. To trouble shoot, remove your clean-out cover and look to see if there is standing water. This will indicate that it is your main sewer. If no water is present in the clean-out this usually indicates a smaller drain is plugged; for example, the laundry tub.
How do I know if my sewer line is a candidate for a liner? If your sewer has roots in multiple areas, or multiple areas that need to be repaired, a liner can be cheaper in most cases than repairing the sewer in 2 or 3 spots.
