Most irrigation companies install the same controllers, the same pipe and much the same heads. The part that actually differs between one quote and another is how the pipe gets into the ground — and that gets decided before anyone writes you a number.
There are two ways to do it.
The fast way
A vibratory plow pulls a blade through the ground and feeds pipe in behind it. Nothing is opened up, so it is quick, and on a large open site with nothing in the way it has its place.
What you give up is sight of the work. The blade goes where it is pushed, through whatever is in its path, at whatever depth the operator has set. Nobody sees the pipe go in, and nobody inspects a fitting before the ground closes over it.
The slower way, and why we use it
We cut the sod, dig the trench, set the lines, and lay the sod back.
It takes longer. Here is what the extra time buys.
1. The lawn recovers instead of scarring
Cut sod goes back as whole strips and knits in within a couple of weeks. A plow leaves a raised, wavy line where the ground was forced apart, and on an established lawn those lines stay visible for months — sometimes a full season.
One of our customers put it better than we would: “When they were done, you could hardly see that any work had been done.” That is the standard the method is aimed at.
2. The pipe goes in at the right depth
In an open trench, depth is something you can see and correct. With a plow it is whatever the machine held on that pass. Shallow pipe is the pipe that freezes first and the pipe a mower or a fork finds later.
3. Fittings get inspected before they are buried
Every joint is visible before the ground goes back. A fitting that is not quite seated is a five-second fix in an open trench, and a dig-up in two years once it is under a lawn.
4. What is already underground survives
Established roots, cable, existing drain lines and the edge of a patio all dictate where a trench should run. You can route around them when you can see them. A blade cannot.
5. The system is easier to live with afterwards
Lines that were placed deliberately are lines somebody can find again. When a head needs moving or a zone extended, the work is a small job rather than an excavation.
Where the difference shows up
Not on the first day. On the first day a plowed system and a trenched system both water the lawn.
It shows up a fortnight later, when one lawn has closed over and the other still has lines across it. And it shows up in year three or four, when the system with shallow pipe and unexamined fittings starts failing in the places that are hardest to reach.
What we will not do
We will not quote a job on the basis of being the quickest crew on the street. If speed is the deciding factor, there will always be someone faster.
What we would rather be is the company whose work you cannot see a month later, and whose system you are not thinking about in five years.
