I'm renting a place with a large yard that I have to keep watered. I've been provided with long hoses and two sprinklers, the kind that sweep right and left, with an arm that interupts the stream in rhythmic fashion. The problem is, after a few days, both stopped "returning;" when they go into the quick-ticking mode, where they're supposed to return to the right-hand starting point and start ticking left again, they just remain stuck in the extreme left position, quick-ticking for nothing.
At least one will return to something like normal operation if I let it sit unused for a few days; the other one just went out of service last night, so I don't know if it'll come back online or not.
Is there some kind of maintenance I'm supposed to be doing to prevent this from happening? '
Thanks.
