An effective way to clear an underground drain is by using a drain bladder, also known as a ball bag.
Using a Drain Bladder to Clear Clogs
One practical method for tackling stubborn clogs in underground drains involves a specialized tool designed to deliver a powerful burst of water: the drain bladder.
What is a Drain Bladder?
A drain bladder is a simple yet powerful device specifically made for clearing drain blockages.
- Construction: Essentially, this device is a deflated balloon produced from heavy-duty rubber.
- Purpose: It's designed to be inserted into the drain pipe and then activated.
How the Drain Bladder Works
The mechanism is straightforward but effective in dislodging clogs:
- Insertion: The deflated bladder is inserted into the drain opening, as close to the suspected clog location as possible.
- Activation: It is then connected to a water source, typically a garden hose.
- Expansion and Seal: As water fills it, the bladder expands, creating a tight seal against the inside walls of the pipe.
- High-Pressure Flow: After it's filled with water and the pipe is sealed, the bladder will deliver a huge flow through the pipe, pushing against the clog with significant force.
- Clearing the Blockage: This high-pressure flow helps in breaking up and flushing away the clog material, restoring proper drainage.
Using a drain bladder is a focused approach that leverages water pressure directly at the point of blockage to clear the line.
