Repair or replace, explained upfront.
Every sink, shower, toilet, and appliance drain ties into one main line. Because it handles all that volume, the main line is prone to grease, scale, flushed debris, and root intrusion. When it slows or stops, you may see water backing up into the lowest part of the house.
Our main line plumbing services clear the blockage, then check whether the pipe itself is sound. If there's damage, we explain the repair options rather than just clearing the line again.

Common questions about main line clogs and repairs.
The main line is the large drain pipe that collects wastewater from all the fixtures in your home and carries it out to the municipal sewer or septic system. When it clogs or breaks, it can affect every drain in the house.
Signs include several slow drains at once, water backing up in the lowest fixtures such as a tub or floor drain, gurgling toilets, sewage odors, and wastewater rising when you use a sink or washing machine.
Common causes include grease, scale, flushed wipes and paper, tree roots, and pipe damage or low spots that trap debris. Older clay and cast iron lines are especially prone to root intrusion.
Yes. Most main line clogs are cleared with a cable or hydro jetting through an existing cleanout. Digging is only needed when the pipe itself is damaged and requires repair.
An isolated break can often be repaired. If the line is old and damaged in multiple places, replacement, including trenchless options, is usually more reliable and cost-effective over time.
