Signs of Hidden Sewer Line Problems

Sewer issues often develop slowly underground before they cause obvious damage inside your home. Catching the warning signs early can save you from a much larger repair. Watch for the following indicators:

Recurring drain backups

If multiple drains in your home are slow or backing up at the same time, the problem is likely in the main sewer line rather than a single fixture.

Sewage odors indoors or outdoors

Foul smells near floor drains, in the yard, or around clean-out access points suggest sewage is escaping from a crack or break in the line.

Unusually lush or wet patches of grass

A soggy or green spot in your yard above the sewer line can mean that the pipe is leaking and fertilizing the soil with wastewater.

Foundation cracks or settling

Persistent sewer leaks can erode the soil around your home's foundation over time, leading to structural movement that shows up as cracks.

If you’re noticing any of these, a sewer camera inspection is the fastest way to confirm the cause and location of the problem without unnecessary digging. Give us a call today to get started.

Minimally Invasive Sewer Line Repairs You Can Depend On

Not every sewer problem requires tearing up your yard. For many Daly City homeowners dealing with partial blockages, minor cracks, or root intrusion, targeted sewer line repairs resolve the issue without major excavation.

We use camera inspections to precisely locate the problem before any work begins, so we disturb only what’s necessary. We also handle water heater repairs and other plumbing services, so if we find related issues during our inspection, we can address them in the same visit.

Our approach to every job focuses on accuracy and efficiency. We’ve handled sewer work throughout Daly City, CA, so we understand the local soil conditions, pipe materials, and layout challenges that come with homes in this area.

When Repairs Aren't Enough

Sometimes the damage is too extensive for a simple repair, and sewer line replacement becomes the right call. We offer several methods depending on the condition of your pipe and the access available on your property.

Trenchless Pipe Lining

The trenchless method involves cured-in-place pipe lining, in which we insert a resin-saturated liner into the existing pipe and inflate it against the pipe walls. Once it cures, it forms a new pipe within the old one, sealing cracks and restoring full flow without excavation.

Pipe Bursting

The pipe bursting method pulls a new pipe through the old one while simultaneously fracturing the damaged pipe outward into the surrounding soil. This approach is ideal when the existing pipe has collapsed or deteriorated beyond lining, eliminating the need for a traditional open trench.

Complete Excavation for the Toughest Jobs

When a pipe has fully collapsed or is too misaligned for trenchless methods, a full sewer line replacement through excavation is the most reliable solution. We work efficiently to minimize disruption and restore your yard to its original condition as closely as possible after the job is complete.

"Called Flow Master Plumbing about replacing a leaking drain pipe, they came and gave me a estimate, and came the next day and did all the work in one day. Very professional, prompt, and courteous. Highly recommended if you have any plumbing problems."

- Matthew Bogoshian

"Fergal took my call on a Monday morning and had Connor arrive in two hours on the same day. Connor diagnosed a potentially serious issue affecting me and my neighbor in the same building. He graphed the piping so we could understand the piping flow and the likely problem and then explained it all to me and my neighbor. The next day, he and Emmet fixed it, tested all of our water systems, and assured us we are water tight. Thank you!"
