I am currently considering a bid to install a sprinkler system at my residence. The contractor stated he is using Hunter pgp adjustable sprinklers, Irritrol valves and "Curbstop" fitting on the main water line from the city. All connections are brass and K grade copper and he is using a Rainbird timer. I know nothing about sprinkler systems and am looking for advice. Total install is approx $2,000 for a simple system, no drips or anything special on approx 1/4 acre. I basically just want to make sure I wont end up replacing/repairing it constantly. Thanks for your help!!
