Why pits are needed
Pipe bursting needs room to launch the bursting head and new pipe at one end and to receive them at the other. That usually means a pit near the house or cleanout and another toward the property line or main connection. Lining often avoids pits by working through a cleanout, but a small opening may still be needed to install a cleanout, reach a connection or deal with a collapsed spot.
In many Fullerton front yards, the sewer path crosses lawn, a walkway, a driveway or planters, and sprinkler lines are almost always somewhere nearby. Small pits are far less disruptive than a long trench, but they still land somewhere specific, and that spot is worth agreeing on before work begins.
Before the first shovel
- Have the pit locations marked on the ground and noted in the estimate
- Confirm utilities have been marked through 811
- Point out irrigation lines, valves and landscape lighting you know about
- Move vehicles, planters and outdoor furniture away from the work area
- Ask where excavated soil and equipment will be staged
- Agree on how pets and children will be kept clear of open pits
Restoration: what to pin down in writing
| Surface | Question to settle | Typical options to discuss |
|---|---|---|
| Lawn | Will soil be compacted and graded level? | Backfill only, seed, or sod replacement |
| Concrete driveway or walk | Will cut sections be replaced? | Patch, full panel replacement, or left for you |
| Pavers | Will they be lifted and reset? | Reset existing pavers or replace damaged ones |
| Sprinklers | Who repairs lines cut during digging? | Contractor repairs or homeowner handles |
| Planting beds | What happens to plants in the pit area? | Set aside and replanted, or removed |
Illustrative example: a pit under the driveway
Illustrative example. Not a real job or customer.
A homeowner's lateral runs diagonally under a concrete driveway. The bursting plan calls for a receiving pit at the edge of the driveway near the sidewalk.
- The homeowner asks whether the pit can be moved into the adjacent planter instead.
- The contractor checks the pipe's depth and route with the locator.
- The pit is relocated a few feet into the planter, avoiding a concrete cut.
- The estimate is updated to note the new location and planter restoration.
A short conversation before work started saved the driveway from being cut. This example is illustrative, not a real job.
Questions to ask
- Can either pit be moved to a less costly surface?
- How long will pits stay open?
- Who inspects the pits before they are backfilled?
- Is restoration included in the price, and to what standard?
Common questions
How big are the pits?
That depends on pipe depth, equipment and soil. Ask the contractor for approximate dimensions for your job.
Will the ground settle afterward?
Poorly compacted backfill can settle. Ask how backfill will be compacted and what happens if it sinks later.
Can lining be done with no pits at all?
Often, if there is a usable cleanout and the pipe suits lining. A new cleanout or a collapsed spot may still require a small opening.
