If you have a problem with your sewer, and you are within CVSan’s service area, remember to CALL US FIRST. We will inspect our sewer main lines at no charge to you. If it is then determined that the problem is not in the main sewer line, you may wish to call a plumber to check your private sewer lateral (the pipe from your building or home to the main) for a blockage. If you call a plumber before calling CVSan to check our main sewer line, you will be responsible for all charges incurred by the plumber.

What causes sewer blockages?

Some of the most common causes of sewer blockages are grease, debris, or foreign objects in your sewer lateral or our sewer main lines, partial or complete blockage caused by tree root intrusion into sewer lines, and sewer line collapse caused by old or deteriorated pipes or debris entering the sewer system from illegal connections.
