Methods of Unblocking Drains: Pros and Cons of Different Methods
Methods of Unblocking Drains
Why Do Drains Block?
Blocked drains can occur for several reasons, including:
Grease and Fat: Pouring grease or fat down the sink can solidify and create a blockage.
Tree Roots: Roots from trees and shrubs can infiltrate drainage systems, especially if there are cracks or leaks.
Broken Pipes: Damaged or collapsed pipes can restrict water flow and cause blockages.
Now that we know what causes blockages, let's look at the different methods to unblock drains and the advantages and disadvantages of each..
Rods.
Portable, no parking issues.
Can work from upstream without flooding.
Disadvantages
They can get stuck.
They can cause damage.
They can come unscrewed.
Health and Safety issues, with the potential to fall into the manhole.
Rods can be lost in the drain.
Cable Machines.
Portable - no parking issues.
Can work from upstream without flooding.
Good at breaking up blockages.
Disadvantages
Heavy.
Cables rotate in your hand.
Entanglement can cause injury.
Jetting Machines.
Highly effective for large and stubborn blockages.
Cleans the whole pipe.
They can be used over long distances.
Disadvantages
Noisy.
They can cause injury if not used correctly and, therefore require sufficient training.
Potential for burst hoses.
High-Speed Milling Machines
Portable.
They can work round bends.
Safer than traditional machines.
No Water is required.
Disadvantages
Requires electricity.
Heavy.
Potential for damage and injury if used improperly and therefore requires sufficient training.
Jetting Machines.
Can jet very long distances.
Can jet large bore pipes.
You can empty the manhole.
They can suck the blockage so you are not sending debris down the drain.
Disadvantages
Noisy.
High reaction force.
They have complicated operation controls.
Requires regular maintenance.
Blocked drains are a common issue, but with the right knowledge and tools, they can be effectively managed. From simple rods for minor blockages to powerful jet vacs for heavy-duty cleaning, each method has its place. Understanding the advantages and disadvantages of each can help you choose the best approach for your specific situation.
