    Hi,

    I'm new to this forum, Recently I bought a house and planning to install a lawn sprinkler system. Our town does not allow to place any heads in 'Right of Way' and 'Easement'. I did some rough sketches for both sides and rear of the house. But having hard time to draw for the front.

    I'm inserting an image. Could you please help me to place the heads so that all the areas in front will be covered.

    Thanks in Advance.

    Can you resize the pic? Also, do you know your available gpm/ psi?

    Thanks for your reply. PSI is good, around 100. Sorry for my image, re-sized but it is not good. I'll try to fix it after work.

    This is for my zone1 in front of my house, the dimension is around 60' X 60', in front I need to leave around 16-18' (ROW) where I can not place any heads, in left side, I have to leave 15' (Easement), no heads over here too.

    Thanks!

    Do your know your exact gallons per minute and dynamic water pressure? These figures are what you will design the system around. Until you know this, a design is null.

    GPM is around 22-25 from 3/4 inch supply, not sure about Dynamic Water Pressure.

    Thanks!

    I apoligize for asking so many questions. Is this a city water supply or well pump? Dynamic pressure is a necessary part of the equation in order to determine how many heads to put on a zone.

    No, you don't have to apologize, it is a city water supply.

    Thanks!
