Shower Drain Offset Problem: Brief Overview

Shower Drain Offset Problem

Let’s first talk about what the shower drain offset is and how can we know the drain is offset. Sewer lines can occasionally encounter issues like being “offset.”

An offset sewer line has joints that are no longer properly connected, causing the two pieces of pipe to become misaligned.

Other than pipe collapse or deterioration, the most troublesome plumbing issues a homeowner can have are pipe offset damages.

Offset pipelines are not only difficult to fix but also costly projects. However, in this article, we try to show you a variety of possible causes, issues, and solutions you can take in response.

Probable Reasons for Shower Drain Problems

If you want to solve this shower drain offset problem, then, first of all, you have to know the probable reasons behind this. Let’s discuss some of the major reasons for the problem-

  • Roots

Tree roots are one of the main culprits of this problem. Tree roots on your property have the potential to grow through, beneath, and above the drain pipes.

Usually, what happens is that the roots locate a tiny hole in the hub of the pipe and enter the pipe through that hole. After this, the roots spread and cause the joint in a drain pipe to slide out of place, which may cause the joint to become offset.

Mostly, clay pipes get affected by these tree roots.

Nothing will prevent roots from spreading where they wish to. Some of the tree roots are so strong that they can also crack a 4″ thick concrete wall.

So, whenever you will face this offset problem, thoroughly observe your drainage system to find out if there is any root or not.

  • Earth Settling or Shifting

It might sound unbelievable, but another reason for offsets is the earth settling or shifting. Typically, this occurs with clay drain pipes.

The most extreme example of earth shifting would be an earthquake. An earthquake can be so powerful that it can break your entire drainage system.

Cast iron pipe is safer than clay pipes in this situation because cast iron pipes tend to stay together and form a belly where the ground has moved. So the offset problem is not possible to happen.

  • Aging of the Infrastructure

Shower drain offset problems usually happen in old houses where the drainage system is also old. Because the drain pipes face a lot of environmental changes over the years and get damaged gradually.

  • Poor Installation

Poor installation is one of the reasons that your shower pipe becomes offset. Poorly installed pipes can not tolerate vibration, pressure, and thermal change. So the shower pipes easily get offset.

  • Pipe Corrosion or Deterioration

Pipe corrosion or deterioration can be another reason. Usually, this happens in the steel pipes. When the joint of the two pipes face corrosion, it starts to wear off, and, at some point, the two pipes get separated from each other, leading to the offset problem.

How To Solve The Offset Problem?

As we have learned what causes this shower drain offset problem, now it’s time to know how to solve this problem-

  • Cleaning the Drain

There can be a lot of trash and tree roots in the drain, which causes the offset problem. That’s why the first step should be cleaning the drain properly.

Look for the roots or trash and clean them thoroughly. Rejoint the pipe and inspect if the water flows smoothly without any waste.

  • Video Camera Inspection

This is kind of a tricky method and needs a professional’s help. After cleaning the drain pipe, it is important to visually verify the sewage line’s length with a video camera examination.

Technicians can then precisely diagnose the problem and develop solutions after doing a visual investigation.

  • Pipe Lining

Pipe lining can be an amazing solution to this problem. Pipelining is a method of fixing the drain pipes without digging. It is a technology of inserting a rigid, better pipe inside the old, broken pipe to ensure a better water flow.

You can use this pipe lining method to your entire shower drain or just on the spots where offset problems happened. As the new pipe is rigid and seamless, this can provide a better and long-lasting solution.

  • Traditional Method

The traditional method of repairing offset drain is quite time-consuming and requires a lot of work. In this method, you have to dig up your yard and change your whole drainage system.

First of all, you have to remove the old pipes, and then replace them with new ones.

This process is also quite costly. You will need professionals for this. You have to pay them for digging and burying also. The cost of the pipe portion that is being repaired or replaced will also be added.

So overall, this traditional offset repair method is expensive. But the good thing is that you will easily find this type of professional who can do this work as no advanced technology is needed for this method.
