Soaker Hose available in two sizes micro 4mm internal and main 13mm internal.
The hose is designed to leak water along its entire length slowly, to areas such as borders, and veg patches.
The water leaks slowly from the length of pipe, allowing larger areas to be watered but use less water.
There are no holes in the pipe it is porous and can be used above or below ground.
If you see any jets of water shooting from the pipe, then the water pressure is usually to high and you will need to install a pressure reducer.
