As a company we are large and spread out . We have 2 irrigation specialist in our company located in areas to far to drive to mess up their day of work(4 hour drives) They are both out of service for this week they are on vacation , local to me i have a neigborhood with alot of low grade systems and i have personally never did any of this kind of work ,and this is my situation . we had alot of storms last week and they came into the complex to mow and a few of the homeowners had no irrigation at all working the stom broke limbs and damaged the back flow preventers so after looking over the situation i found there is no irrigation company left in the area after a heart attack ended a company there so i decided to repair the pipes up to the manual valves (yes manual ) then 1 HO asked me to come over and this is the bad part. He wanted his system repaired and functioning .it to is manual valve system but never been on since he bough the home 7 years ago .after a hour we located his water main under thick bermuda and made the repairs to the piping to find there was NO flow into the lawn .........meaning i have to locate the heads in the lawn and uncover them to allow them to pop up and activate in the bermuda. Now assuming i repaired the piping and the valves are functioning correctly ,knowing i had water to the BFP how do i actually locate the heads. He told me the system was 10 + years old and they installed a large pool and bed in the rear but had did little to nothing in the front. where do i begin to locate the heads .. I found 1 on the corner of the drive near the curb but none of the others are visible with the lawn cut to 2'' what is next??????? I know at best i will have to repair several of the heads if not the whole system with my luck. Also I am considering after the money i seen that day in repairs only that there is alot to be had in certian areas . and i would like to find all of the information on installs and repairs i can so i have a better understanding on the time managment ,pricing ,and servicing of this type of work . so i can prep a guy at all of my locations for these types of situations. my guys were trained by this LCO that is no longer in business and it wil lbe at the end of the month before i can pic their brains about it at our meeting.
