Should I Push Drain Chains Through a Blockage or Go Past It and Pull Back?

When using a drain chain to clear a clogged pipe, a common question arises:
Is it more effective to drive the chain straight into the blockage, or should you first break through and then pull back?

There are different opinions, but here’s a method we’ve found to work reliably in many tough scenarios.

Our Go-To Approach: Break Through, Then Pull Back

Begin by wrapping the chain tightly around the shaft.
Then, push the shaft forward until it has completely passed through the blockage. Once you’re past it, retract the shaft, open the chain, feed it back into the same spot you pierced, and pull it backward through the obstruction.

Why Pulling Drain Chains Has the Advantage over Pushing

You generate more force pulling than pushing. That extra power makes it easier for the chain to grip and tear into the blockage, giving you a better chance of breaking it up and restoring flow.

While chains are engineered to function in both directions, this method tends to give better results when dealing with stubborn blockages.

Choosing the Right Technique

Both pushing and pulling are legitimate ways to use a drain chain. The best option depends on the specific clog and pipe you’re working with.
That said, if you’re after maximum impact, try going through the blockage and then pulling back.
