As most of you know I am new to the irrigation side. I have had several people call and say they have one head bad but when I inspect the system they really have plenty of things that need replaced. Is this the way it usually goes? I have been trying to fit the irrigation in along with my other services but am having trouble with scheduling times. One person said they need one head replaced so I went by on a Sat afternoon and ended up changing 13 and fixing one leak. Dr office called and said they had one head off and ended up replacing 4 rotors, 5 sprays and replacing two nozzles. This seem to be the norm so far. How do y'all schedule the time between service calls? If it is much more that what was originally told to you do you come back or just go ahead and fix?
