Default Irrigation system: trenching vs trenchless?

I just got a quote for an irrigation system for my yard. I was
explained this system does not require trenching and for this reason
is less expensive. He also explained that there are no other
differences in terms of performance or anything else.

I would like to know if is this information is correct - that there
are no major differences in the systems except for the installation
method and the difference in damage to the lawn. Are there any other
benefits involved in trenching for an irrigation system?

Thanks for your help

Default Irrigation system: trenching vs trenchless?

In our part of the woods we see a machine called a DitchWitch that trenches
a yard to burry pipe. Our code requires electrical to be buried 12" deep
inside of 3/4" thick wall pipe. For PVC water pipe, I guess their is no
local code governing lawn sprinkle systems but if it's just down 6" and you
start spading a flowerbed in the future, Your sure to cut it in half. It can
be fixed but mostly the only problem will be a very wet patch of lawn until
you discover the problem. Some contractors take an easy way during
installation by simple splitting the ground apart with a shovel - not
removing any dirt - then tamping the split after laying the PVC 6" under the
surface. It's your call. Jack

The trenchless approach is the most common because it's faster, less
messy, and cheaper. A machine is used that pulls the pipe through the
soil. It's supposed to lay the pipe at least 6 inchs deep. The
problem is that in areas where the earth is hard, maybe a root, etc,
the pipe can wind up much closer to the surface. This then becomes a
problem if you decide to aerate the lawn, as the core aerator can
puncture the lines. It's easily repairable, however it is somewhat of
a nuisance. Sometimes you can aerate without a problem, or you can
wind up with a couple of repairs.

I'm not sure where you are, but here in NC we have very hard clay and
my neighbor had a system installed using the "pipe puller" which is
trench less. I sat and watched the machine work and the first thing I
noticed it was not burring the pipe deep enough and he will have
problems aerating the lawn. This fall he aerated and seeded. When he
turned on water it was leaking from everywhere. Also, even if you hit
the pipe and did not brake it right away it will put micro cracks in
the PVC and over time it will crack.

Contractors love to use it because it saves them time and money. Pay
the extra bucks to have it trenched and don't worry about the extra
mess you will never have to worry about hitting pipes.

Or install it yourself, If you think you might want to I can shoot you
a web site that is the best on the net for do it yourselfers. Do not
use the free design offers from the manufactures or you will be sorry!

I also have some other tips for you if you choose to have a contractor
install your system, that will have you some major bucks down the
road.

Thanks for all the comments. Although I would love to do it myself,
unfortunately I don't have the time/experience to start with a project
like this. So, when hiring someone, beside the installation system,
are there any other questions to ask to make sure they will make a
good job? (I have obviously asked for references of recent and old
costumers). Thanks again,

John F.

Hi All,

I was reading all these post's because I will be doing a sprinkler
system in the very near future. I should say, I will be adding to the one
that is already there. I would love to have that web site you were talking
about and any other tips that you could provide. A sprinkler systems is
something I have never done and the lessons learned and other info would be
great. Right now there are three zones connected, but only two work and I do
not know how to figure out which one belongs to what number on the timer
without cutting wires until I find the right one. Also I will be adding the
other three zones to have a complete six. We just bought this house and are
doing a lot of landscaping and will need all six zones.

Thanks for any info provided.
