Hey All,

I am in need of your help once again. *I have a 38 year old house with
a 10 zone sprinkler system. *Most of the heads were corroded copper
ones that I assume to be 30+ years old. *I started swapping them out
with Orbit 4" popups from HD/Lowes. *The problem is my sprinkler
system does not have head to head coverage but does reach the entire
perimeter. *The old copper sprinklers diffuesed the water so even at
max opening, the water soaked the gound from 2" up to 10' from the
head. *These new Orbit sprinklers soak the ground at 10 feet but it's
dry from 0-6 feet from the sprinkler. *I talked to Orbit tech support
and they said I needed head to head coverage. *Does anyone make a
reasonable cost popup sprinkler that diffuses the water from say 0-12
feet? *I have googles and googled and am wits end. *I got my system
working and hate to have to rip it all out or double the amount of
heads to get proper coverage.

TIA,

Derek


I like (& have used for nearly 30 years) Toro 570 Series Pop-ups.

they make 3", 4", 6" and taller pop-ups....

YEARS ago we used Champion brass pop-up heads with brass inserts.
The harder water in SoCal tended to foul the spray inserts & the pop-
up was pretty short.

You can buy the 570's as "body" only or with spray heads.

If you get the spray heads separately for can choose the spray radius
that suits your spacing. (5', 10', 12', 15')

If your current riser locations are 10'...you can use 10' spray heads
(blue stripe).

If the spacing is more than 10', use a spray head with a longer throw

12' (brown stripe) 15' (all black)

I use 3" but depending on your lawn species you might want 4" but the
bodies are a bit tall.

These Toro's have been very reliable and on my oldest installation
(1980) I just recently replaced all the heads.

Depending on your lawn size & layout you could consider RainBird
impluse sprinklers; Maxi-Paw or Min-Paw.
A minimum set of strategically placed sprinklers can water an entire
lawn. Depending on the size of your zone valves and water supply
(gpm & pressure) you could run as many as a half dozen sprinklers per
zone.
