It doesn’t have to be. Most users who are new to the product will place the LeakyPipe onto the surface, just so they can see what it does. There’s nothing wrong with that. You just loose a bit of efficiency as the exposed, top surface of the pipe that isn’t being touched, tends to dry-off and is "slower” than it would be if it was covered. Once you are happy your system is working, we recommend covering with a mulch or soil as LeakyPipe works most efficiently this way by 'wicking' water into the soil around the whole of the pipe, rather than just where it lies on the ground.
Sometimes surface-placement is just more convenient both for installation and to allow easy repositioning at a later date. Repositioning may be necessary for either a change in the planting, or to make for convenient digging, or perhaps it is finished with for that area and can be relocated to another site, getting more value from the product if you’re a Professional. |
