Main Line Drain Cleaning

Your main line carries every drain in the house to the city sewer. When it clogs, water backs up at the lowest drain — often a basement floor drain or tub. Zenith clears the main line through your cleanout and can camera-inspect it to see what caused the blockage.

Frequently Asked Questions

What causes main line clogs?

Tree roots, grease, wipes and other non-flushable items, offset joints and sagging sections of pipe are the most common causes.

What if my home doesn't have a cleanout?

We can sometimes access the line another way. If your home has no usable cleanout, installing one makes future cleaning faster and less disruptive.
