This is what I mean. They are available in most merchants. The one I have is encased in plastic 20 metres long cost I think 500 Baht ish from Home Pro.



Drain cleaning springs are essentially very long flexible springs which you guide down the waste pipe and turning as you go.

You can buy different size springs depending on whether its for for large or small pipes and different lengths. Can be very effective but a bit messy and not very pleasant to use especially if you use one for toilet blockages!

In North America we don't waste words. We call it a snake.
