After watching a posted video online of a new Irrigation system installed by Walker Irrigation I was painfully reminded how improper installation of new systems has been responsible for giving this Industries a poor reputation.

* Wasteful over spay and run off onto hard surfaces
* Damaging over spray onto house exterior
* Mixed type of sprinkler heads operating on the same zone
* Spray patterns blocked by plant material
* Excessive pressure
* Low distrabution uniformity
