Irrigation System Leak Detector
I have a minor water leak in my irrigation system. I lose about 3-4 gallons every 6-8 hours. My system irrigates almost one acre and due to the small amount of lose I haven't been able to figure out exactly where the leak is. I'm guessing that I have a cracked pipe in my loop line somewhere since the leak occurs when the sprinkler system is not activated. I supply my system with a 5 hp pump with 4 gallon storage tank that keeps the loop line/irrigation system pressurized at all times between 40-60 psi. When it drops to 40 psi the motor kicks on and then shuts off at 60 psi. Since the supply tank is only 4 gallons it only takes about a minute to refill it but the constatnt on/off on the motor every 6-8 hours isn't good for it (a $900 Baldor motor) and the leak just is a PITA since I can't find it.
Does anyone know who manufacturers/sells a irrigation system water leak detector? I've seen one in use in the astr but I can't seem to locate one to buy it.
Thanks for your assistance!
