We had a home built by a local builder about 3 years ago, and

during construction except for the sprinkler layout (I was out
Call the sprinkler company that did the work and get a copy of the
plans.
That is a fantastic idea. I am normally skeptical of the
subs that build homes around here, somehow I doubt they
keep blueprints. Case in point, we had a fence installed
a few years ago. Before the fence could go in, the utility
companies had to come out and mark where the buried utility
(water, electric, phone, cable) lines were. I knew where
they all were (except for water of course), and when the guys
came out to spray paint my grass, they were *waaay* off.
Luckily I didn't care 'cause the fence was going in the
backyard and both the actual lines and the waaay off
painted lines were on the side of the yard. But it just
shot to hell my confidence in construction subs to accurately
document what they do except when it a) costs a lof of money,
Just for the record, those guys don't go by documentation
afaik. They
use a detection device to find lines. For one thing, documentation
can be bad. IIRC, the phone number in Md. is 800 MISS UTILITY, or
MISS UTI.
or b) lives are at stake if the result of what they do is
misused.
But lives are at stake if they cut a gas or electirc line. Rarely,
but they're trying not to kill anyone.
I know they do use documentation for the water mains in my n'hood.
The builder economized on pipe and didn't use the flexible stuff, and
we've had at least 3 water main leaks in 26 years, and we only have 4
or 5 blocks of streets. Each repair is about 10,000 dollars.
They do come with a diagram of the streets, or the water company comes
out first with a microfiche, and marks where the pipe is near the
visible leak. I think they have been close to accurate, if not
perfect. OTOH, our main water main is in a the shape of a P, and
everyone lives on the top circle part, and they're supposed to be able
to turn off the water in two locations with only 10 or 20 houses
without water. Instead they always use the main valve and none of us
have water** They seem to say they can't find the other valves.
**No big deal to me, but others complain.
Anyway, I'll give them a call and see what I can "dig up"
so to speak.

of the 5 zones of the sprinkler system (as the pool's decking
The whole zone? Won't that be at the water valve and isn't that a
known location?
Umm.. you're talking to a sprinkler idiot. I know what a "valve"
is but I don't know where the valves are in my system. I assumed
they were in some nether region in one of my walls. I'll see
what the contractor says.
They're not IN the walls. They inside the basement or more likely
just outside the basement wall. The water comes from the basement or
pops out of the ground, and then comes the elecxtric timer, the
electric valves, and the outputs, going off to all the zones.
AFAIK,
no one ever buries all this.
Even if when things are buried, I think there are sometimes valves
accessible with a long wrench and a hole. Maybe I'm thinking of golf
courses, with manual valves to turn on sprinklers.
Any tips on locating buried water lines (aside from "going
caddyshack" on the backyard!). Any pointers to a typical
Are you supposed to drain them every winter? Does that mean you know
where the far ends are? Open one drain at a time and see which heads
are on the same line, because they are the ones that won't have much
pressure, or which will stop spraying first when the water turns off.
Or disconnect/turn off one zone or all but one zone at the valve, if
that is possible (surely it is) and learn which heads are in the same
zone that way.
No winter draining, why would one want to do that anyway? If it's
for protection from freezing/bursting, no issues here, I'm in
Yes.
central florida and the ground never freezes. As for the zones,
I can map them (as you suggest below) as I have independent control
over all zones. I know which heads are on which zones. I just
wonder how the pipes snake from the main water supply around to
the heads. For example, the one zone that I want to preserve costs
of 4 rotary heads, all at the back fence in the back yard. Does
the supply line cut straight back in the middle of the backyard,
form a "T", with each end of the T supplying 2 heads? Or does the
supply line come up the side of the backyard, and run across the
whole back fence?
Yeah, you're right, good question. Generally the shortest run but
there are other factors. Putting more than one line in the same
trench for part of its run is a factor.
