Design/Installation Concerns

We just had a system installed by a very reputable
contractor who also has installed many of my neighbors systems. At this time we have yet to calibrate the
system and it may be that tomorrow we are able to tweak a few things which lead
to improvements.

Right now I am looking for some advice and also some talking
points so I can be best prepared. I
normally research the crap out of things like this before moving forward, but
the referrals were good enough for me to forego my usual process.

Our system is as follows:

5 zones (Z1 = 6 rainbird 5000 rotors, Z2 = 10 hunter pro
sprays, Z3 = 3 rotors, 3 sprays, Z4 = 6 rotors, Z5 4 rotors) We have a Weathermatic smartline SL1600
controller with rain sensor and Wilkins pressure regulator. Our yard is approx .7 acre and we have some
gradient in the back.

Most of the rotors seem to be working fine, although the
pressure doesn’t seem very high. Most of
our neighbors have misting actions and high arc to the coverage yet ours look
more like a stream of water coming out of a garden hose but a lot less of
it. Our main issue is zone 2. We have a combination of 12” and 4” sprays on
this cone and the 4” pop up around 2 inches and the 12” don’t come out at all,
instead spewing water all over the path.

The other sprays on Z3 appear to work fine.

Z2 does go under the sidewalk so I had inquired about a
potential blockage.

We were also told to call the City and ask them to test the
meter. We have 75psi at the street but
were told they couldn’t test the incoming pressure as this would require meter
removal. The City did state that this would
be very unusual for the meter to be the issue.
Our house was new build in 2013.

I bought a pressure gauge and put it on my hose bibb… it
reads 50psi.

The contractor is coming back tomorrow and is suggesting we
remove the pressure regulator and also adjust the sprays. He is adamant that we should insist on an
incoming test of the water meter as he has experience of a similar issue
nearby. My next door neighbor is having
his system installed by the same contractor today and my neighbor opposite also
has one. I guess we will wait and see
what happens tomorrow when he comes by to review.

Is there anything else I should be doing / asking at this

The contractor hasn’t been paid yet so I do hold a few

Thanks in advance.
