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

That's kinda the way those popup spray heads work - you need to
overlap the coverage. They do make popup rotors, and popup impact
heads, which would probably do a better job of close coverage. You
might try installing one of those just to see what it does. I'm not
sure, but I think the GPM requirements for the rotors or impact heads
are a lot higher than for the spray heads - you might need to
reconfigure your zones anyway to get the flow rate you need for them
to operate correctly.

RainBird makes the "DualSpray" series of pop-up sprinklers that claim to
water close in as well as farther out. I've seen them at Lowe's: a few
different spray patterns covering radii up to 15ft, IIRC.

A specialist store might have a wider variety.

Corroded Brass? clean them. I hope you still have them, here they are
now 30$ a piece or more and are only make in somewhere like Sumatra,
mine are 30 yrs+ old and the plastic junk that I have a few of, I put
back in the Brass, they dont stick, they take a wrench and a walking
and even mower and car hits. My brass have many different head
patterns and Gpm outputs, compare Gpm ratings on the head pop ups,
they should be stamped so you can match Gpm output and patterns.
Honestly I dont like the plastic ones, they are the only units I have
issues with, sticking, but the Sprinkler maintenance co likes them. I
never saw a plastic one survive a mower.

I don't recall difference between Orbit or Toro or ? Aren't the heads
adjustable? If not, you could have too much pressure. Should water the
entire arc. Loads and loads of info he

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.

Hey Guys,

Thanks for all the advice and the great links to further my sprinkler
education. I recently matched all the heads on the system with Orbit
4" popup dual spray and it seems to be working much better now. I
guess I made a LOT of novice mistakes in the past few years. I do
need to add a couple more heads, but all in all, it's working well. I
have huge pressure at my house and no more than 4 sprinklers per
zone. The lines are 1" and my pressure is roughly ~75 PSI.

Thanks again for all the help.

On a side note. My valves are buried in the yard somewhere and not
all together. Is there an inexpensive way to find them?

We had that issue at our condo, with four of six buried "somewhere". We
dug a hole where the wires exited, took a "sight line" and dug
another...cheap ex. in terms of our time. We tried metal detector and
stethoscope ) Also dug up a lot of concrete doughnuts that had been
buried for many years.
