Way ot i know... ijust hooked my irrigation system up at my home. It is a hunter pro c unit and has 7 zones (4 of which im goingto use). They have it set to run 3 days a week for 30 minutes each time... he said each cycle is the equivalent of a half inch of rain. The question for the peanut gallery is what increase should I expect on my monthly utility bill? It is a separate line and does not require sewage. Lcub has a minimum charge for 1,000 gallons... just didnt know how much that equated to in regards to run time. I'm in the farragut area...
