We have had the sprinkler working for a couple of weeks now and it is fantastic. It is even better than we hoped it would be.
My husband changed the nozzle and it now waters almost the width of the areas where it is used so we only need to move it down the lawn in one direction.
One bonus is the weight of the droplets as we live in a very windy area. The large droplets allow watering which is not too affected by the wind so we can water whenever we need to.
Thank you for all your help. We will be sure to recommend you to anyone looking for similar irrigation solutions.
