What Causes Pipe Bellying And How Do You Fix It?

Pipe bellying refers to a sagging part of a pipe. Uneven pipelines cause slow drains, backups, and pipe damage. It’s a common underground plumbing issue that needs trenchless sewer repair in Springfield, PA. Some cases may combine trenchless methods with excavation.

Pipe Bellying: Causes, Effects, And Fixes

A “belly” in a pipe occurs when a section of the sewer line sags or sinks below the proper slope. This causes water and waste to collect in that low spot. It results from soil shifting, improper installation, or gradual erosion beneath the pipe.

The lowered pipe belly part causes slow drains, major blockages, and backups. It also damages the pipe and causes leaks. If it hasn’t caused severe structural damage, trenchless pipe repair methods can repair and reinforce the pipe. This restores the proper slope and linear direction of the pipe.

Aside from trenchless pipe lining, pipe bursting also works, especially for severely damaged pipe belly sections. This method replaces the whole section in place by breaking up the damaged belly section while pulling in the replacement pipe in place.

Combined Trenchless And Excavation Work

If feasible, a trenchless pipe replacement is the most effective long-term solution for pipe bellying. Many cases combine minor excavation and trenchless methods. Specialists insert new piping along the same path after removing or bypassing the damaged section.

Other cases need a full excavation, depending on the level of damage and accessibility. This approach resolves the belly and upgrades outdated sewer infrastructure.

Not all solutions are achievable with trenchless pipe replacement, however. There are cases of extreme sagging, compounded by difficulties in access or location.

The best way to resolve extreme bellying instances is to excavate the pipe and replace it.

Some minor adjustments are also required to correct the slope and prevent recurring issues. Plumbing technicians also consider surrounding soil conditions and other factors.
