Underground Plumbing FAQ for North Atlanta

Underground issues can be confusing, so this page answers the most common questions in plain language. Zippy Plumber focuses on exterior lines between your building and the street, which means our advice centers on proven underground methods. If you do not see your exact situation here, the guidance below will still help you decide the next step and what to expect during service.

Frequently Asked Questions

1) What is underground plumbing and how is it different from indoor plumbing?

Underground plumbing includes sewer and water lines that run outside the building to the municipal system or well connections. These lines face roots, shifting soil, and surface loads from vehicles, which require different tools and materials than interior work. Because conditions are unique below grade, our technicians design repairs that account for soil, access points, and code requirements for exterior lines.

2) How do I know if I need a sewer camera inspection?

Schedule a camera inspection if you notice slow drains, recurring clogs, gurgling toilets, sewage odors outside, or wet areas along the yard line. The camera shows cracks, offsets, bellies, and roots in the sewer line and records video you can keep. With visual proof, we can recommend sewer line drain cleaning, trenchless sewer repair, or a targeted replacement with confidence.

3) What is trenchless sewer repair and when is it a good fit?

Trenchless sewer repair restores a damaged line with minimal digging by working through small access points. The two most common methods are trenchless pipe lining, also called CIPP, and pipe bursting that replaces the pipe along the existing route. These options are ideal under driveways, patios, and landscaping where preserving surfaces matters and the host pipe still has a usable path.

4) How does trenchless pipe lining CIPP work?

After hydro jetting prepares the interior, a resin liner is inserted into the pipe and cured to form a smooth, durable new surface. The liner seals leaking joints, blocks root intrusion, and improves flow without opening a long trench. Lining is well suited for cracked pipes, minor offsets, and joints invaded by roots, especially beneath finished surfaces.

5) When is pipe bursting better than lining?

Pipe bursting is recommended when the existing pipe is collapsed, crushed, or missing sections that make lining impractical. We pull a new pipe through the old route while breaking the failed pipe outward, which keeps access small and surfaces protected. This method delivers a full strength replacement and is effective for long stretches with severe damage.

6) Do you offer hydro jetting and what problems does it solve?

Yes, hydro jetting uses high pressure water to clear grease, scale, and roots that restrict flow inside sewer lines. Cleaning prepares the pipe for inspection and helps repairs last by removing debris that can hide cracks and defects. Many recurring clogs stop after jetting and a proper maintenance schedule, especially for kitchens and high use properties.

7) What is a cleanout and why should I have one outside?

A cleanout is a capped access point that connects directly to the sewer line for camera inspections and drain cleaning. An outdoor cleanout allows service without entering the building, which keeps interiors clean and speeds up work. Proper placement lowers long term costs and supports fast response if a backup happens again.

8) How do you find underground water leaks without digging up the yard?

We combine pressure testing, acoustic listening, and route tracing to pinpoint the break under soil or slab. These methods let us mark a small, precise access location instead of opening a long trench. Once found, we present options that may include trenchless water line repair, targeted water main repair, or a short open cut depending on conditions.

9) What is trenchless water line repair and will it work on my property?

Trenchless water line repair replaces the service through small entry and exit pits by pulling a new pipe along the existing path. It is a strong option under driveways, walkways, and mature landscaping where surface protection matters. We confirm candidacy with tests and measurements, then pressure test and document the new line after installation.

10) When should a water main be fully replaced instead of repaired?

Full replacement is recommended when there are multiple leaks, heavy corrosion, or material failures along long sections. A new line provides a clean start with modern materials and secure connections that meet local code. Replacement is planned with utility locates, safe staging, and final testing so pressure and flow return to normal.

11) Can you repair a slab leak without tearing up large areas of flooring?

Yes, we verify the leak location with pressure tests, acoustic tools, and temperature checks to keep access small. Depending on layout, we can spot repair the exact section, reroute around the slab, or replace longer runs that extend outdoors using trenchless methods. Surfaces are protected during work, and the site is restored when testing confirms performance.

12) What are the signs of roots in the sewer line and how are they removed?

Clues include slow drains, gurgling fixtures, and backups that return after basic snaking. Camera footage often shows root intrusion at joints or small cracks that admit growth. We remove the roots with hydro jetting, then recommend trenchless pipe lining or a focused repair to seal joints and prevent the problem from returning.

13) How do commercial underground plumbing services differ from residential?

Commercial systems see higher usage, larger pipe diameters, and stricter scheduling needs around customers and staff. We scale sewer camera inspection, hydro jetting, trenchless pipe lining, and pipe bursting for these demands and coordinate work outside peak hours. Managers receive video, measurements, and notes that support maintenance planning and budgeting.

14) Do you serve my location in the North Atlanta area?

Yes, our crews support homeowners, property managers, and businesses across the North Atlanta region. We group nearby neighborhoods under one service area so the homepage can stay consistent while city pages provide local details. If you are within the North Atlanta footprint, we can schedule inspection, cleaning, or repair promptly.

15) How should I prepare for an inspection or cleaning visit?

Clear the area around exterior access points, note any symptoms such as slow drains or wet spots, and avoid running large appliances that use water just before we arrive. We handle 811 utility locates for digging tasks and bring equipment sized for your property. After the visit, you will receive video when available, simple notes, and a plan that explains whether cleaning, trenchless repair, or a small replacement is the best next step.
