    I am getting estimates for a sprinkler system to be installed at my residence and i have a contractor that i think i am going to go with. He handles both Rainbird and Hunter and he personally chooses the Hunter brand, but is leaving it up to me to decide.

    I think i have decided to go with his suggestion (because after all, he is the expert) with Hunter and he wants to install the I20's.

    From what i've read on here, that is a good choice i guess. Just wondering if the spray pattern is a good one. Another contractor i got an estimate from swore by the rainbirds "curtain" spray. How are the I20's compared? Is there a big difference, and will i get good coverage with the I20's?

    thanks for all your comments.

    IMO I20s are overkill in most residential applications. Ask him why he feels that you need I20s over PGPs.

    How big of an area are you looking at watering with them? What sort of water source do you have?

    I agree, I 20s are overkill in residential yard. The new pgj is what i used in a new res yard. I was very happy how they worked. And are bout half price of I 20s.

    I have a little over 2/3 an acre and they'd be run off a well with 3/4 hp pump. Not sure the gpm, but he check it out.

    Do you still think it's overkill?

    Thanks for the responses.

    I use the I-20 much more than the Pgp or Pgj. I like the flexibility of nozzle selection, ease of use and durability of the head.
    With regards to the spray pattern, the spray it self is diffused with a screw protruding through the nozzle, and is adjustable for elevation as well.
    Coverage depends upon several factors, head spacing, available design pressure, terrain of the irrigated area, and weather factors. The I-20 is a good head to use, properly installed, it should last many seasons.

    As long as the design and water source allows., I always offer the customer the option of either PGP or 1-20. I always explain the extra features that could benefit the homeowner such as shut off on the 1-20, a better built contruction (spring, housing threads, and built in check valves) and the extra 3 year warranty.

    More money and their choice. 4 out of 5 choose the 1-20

    I upgraded to the I-20's. The contractor wanted to put in PGP's. I like the fact that you can take out an I-20 head and still have the rest of the zone work. Adjustment is very easy with the I-20 not sure about the PGP. It was worth the $6.00 price difference per head I paid. Get the I-20's glad I did.

    And dont forget the extra 3 Year warranty on the 1-20's. Be sure your contractor offers this to you.

    PGP's 2 year
    I-20's 5 Year
