When your old sewer lateral is too broken to line, pipe bursting replaces it through two small pits instead of a trench across the yard.

Pipe bursting replaces a failed sewer lateral by pulling a cone-shaped bursting head through the old pipe, fracturing it outward while new seamless HDPE pipe follows right behind. It needs two small access pits, not a full trench. In Marina del Rey, it's most useful on building laterals where tight, paved setbacks rule out a trench.
Pipe bursting is a trenchless replacement method. A bursting head is pulled through the existing sewer line by cable or rods, and as it moves it cracks the old clay, cast iron, or fiber pipe and pushes the fragments into the surrounding soil. The new pipe is attached to the back of the head, so it's in place the moment the head reaches the far pit. This page is part of our complete guide to trenchless sewer repair in Marina del Rey.
Pipe Bursting: Pipe bursting is a trenchless sewer replacement method that fractures the old pipe in place while pulling a new, continuous HDPE pipe into the same path through two small access pits.
Because the old pipe is destroyed rather than reused, bursting works where lining can't: collapsed sections, badly offset joints, and pipe that has lost its round shape. The trade-off is that it needs room for two pits and a clear path, so we check nearby gas, water, and electrical lines first.
In Marina del Rey, it's most useful on building laterals where tight, paved setbacks rule out a trench. Paved courtyards and narrow setbacks in Marina del Rey make two small pits far easier to approve than a trench.
We video the line, mark its route and depth, and confirm bursting is the right method for the damage we see.
A launch pit near the house or cleanout and a receiving pit near the property line or main, sized for the equipment.
The head splits the old pipe while fused HDPE follows behind in one continuous pull.
We connect both ends, run a final camera pass, pass inspection, then backfill and restore the pits.
Camera first, always. Every recommendation starts with a recorded inspection you can watch yourself, and a flat-rate price you approve before we start.
Marina del Rey jobs are rarely about lawns. They're about paved courtyards, parking areas, and narrow side yards between buildings, where trenching the length of a lateral would mean cutting up common areas and blocking residents. Pipe bursting keeps the disturbance to two defined pits, which is easier to schedule and easier for a board or property manager to approve. It's especially useful where an older cast-iron building lateral has cracked or collapsed and can't hold a liner. We plan pit locations with management, protect the surrounding hardscape, and restore it when the new line passes inspection.
Marina del Rey is mostly condos, apartments, and townhomes built from the 1960s onward, so sewer problems here usually involve shared building lines as much as single-home laterals. Sandy coastal soil and groundwater close to the surface in many spots let water seep into cracked pipe and make open trenches harder to keep dry. We start with a camera and share the recording with you, your board, or your property manager.

Marina del Rey is unincorporated Los Angeles County, so plumbing permits come from LA County Public Works Building & Safety, not LADBS. Under County Code 20.24.080, the property owner maintains the lateral, and LA County Public Works says that responsibility covers its entire length, including the part under the street. We handle the County permit and inspection so your board or manager doesn't have to.
Example scenario below is illustrative, based on common situations we see. Details vary by property; not a specific customer.
A Marina del Rey townhome complex has repeat backups, and the camera shows a cracked, partly collapsed cast-iron lateral under a paved walkway.
We burst the lateral between two small pits placed at the walkway edges, pulling new fused HDPE along the same route.
The walkway is restored in two patches instead of a full-length cut, residents keep access throughout, and the HOA gets the permit and camera record for its files.
New Pro Plumbing is family-owned and led by Miguel Lopez, and many Marina del Rey customers ask for him by name. We price by the job, not the hour, so the flat rate you approve is the amount you pay. And when we leave, we leave no trace behind.

The Bottom Line
If your lateral is too far gone to line, pipe bursting gives you a new, jointless pipe along the same route without trenching the whole yard. We confirm it with the camera first and quote it flat-rate.
No. Lining installs a resin liner inside the old pipe and relies on that pipe keeping its shape. Pipe bursting destroys the old pipe and pulls a completely new HDPE pipe into its place. Bursting is usually the choice when the old line is collapsed, crushed, or too misshapen to line. Bursting fractures and replaces; lining coats the inside of an existing pipe and cures. Different jobs for different pipe conditions, and one lateral sometimes needs both. Our pipe bursting overview walks through the full method.
They’re sized to fit the equipment and the connection points, typically a few feet across, one at each end of the run. That’s far less digging than an open trench along the full length of the line, and we restore the pits when the work is done. Both pits are typically three to four feet across, sized for the bursting head and the pulling rig, not the full length of the pipe. We stake locations before you approve so you know exactly where they will land in your yard or parkway.
We install high-density polyethylene (HDPE) pipe with heat-fused joints. Fused joints make the new line continuous, so there are no gaps for roots or groundwater to get into. HDPE is heat-fused rather than joined at rings, so there are no interior joints inside your yard for roots to find. Manufacturers rate the material well past 50 years underground, which is why it is a common choice for full replacement.
It can if another line sits very close to the sewer, which is why we locate the sewer and mark other utilities before we start. If the clearance isn’t there, we’ll recommend a different method rather than take the risk. Every job starts with a USA DigAlert ticket, and any utility within the bursting corridor is located and marked. You can verify our contractor license anytime at the CSLB portal.
Usually, yes. We place the two pits at the edges of the paved area where possible, coordinate the locations with management, and restore the paving once the new line passes County inspection. Pit staging in Marina del Rey courtyards, garages, and driveways is a routine part of our planning; we coordinate placement and hours with property management. See Marina del Rey trenchless hub.
