Hi lobell,

Does your land have good slopes or is it flat? How many square feet is a large yard? Do you irrigate 24 hrs or 12 hr or 8 hrs or another time period to use 7,000 gal? How many square feet is the area that you need to irrigate? How do you measure your 7,000 gallons/day? This is a time versus gallons problem. Example: 20 gal/min gives you 20 g/m x 60 m/hr x 6 hr/day = 7,200 gallons/day. What flow and pressure does your pump produce? All that you are asking depends on your system output and daily need. Please state why you think pressure tanks would be an advantage to direct controller irrigation from the pump. Where does your house water come from? Aloha
