Getting soaked

I woke up this morning to find the sprinklers in my front yard still running long after their pre-dawn cycle should have concluded. I watched them for about half an hour before realizing they hadn’t just gotten a late start for whatever reason but that they were actually stuck on (and had been running for hours, egads). This got me feeling anxious because half the yard was being watered at the rate of two separate garden hoses set to maximum flow. I could practically hear the cascade of dollars soaking into the ground.

Naturally, the first thing I did was go to the controller box in the house and turn the system off. Nothing happened. So I unplugged it. Still nothing. Then I went to look in the controller boxes out in the yard and found a bunch of solenoids and wires but no valves of any kind that could be shut off. An hour had now passed and I was starting to get a bit panicky. I opened the local Yellow Pages (so old school, right?) and started calling sprinkler repair companies, and got through more than a dozen before somebody finally answered the phone who could be out in less than an hour.

Another 30 minutes of potable city water went into my now soggy lawn before the sprinkler guy arrived and promptly turned off the sprinkler valve located next to the outside controller box at the bottom of deep, narrow plastic pipe. There are two of these pipes: one is the drain valve and one is the water supply valve. There is no way to distinguish them by looking; one just has to know. Oh, and here’s a helpful safety tip should you need to mess with your sprinkler valves and you don’t know which is which: Always start by turning the valve to the right (“righty-tighty” or off). If the valve is already closed, leave it closed. Apparently bad things happen if the drain valve is opened when the system is on.

Once the sprinkler guy explained to me which valve was which and what they do (which was something I had heretofore never had any need or desire to know), we labeled the two pipes with a Sharpie for future reference. Inside the controller box, he found a blown-out solenoid that he was able to replace. I had looked in that box earlier and it was full of spider webs and water that completely obscured the solenoid so I couldn’t see the obvious damage.

For those of you as unfamiliar with automatic sprinkler system hardware as I am, suffice to say that this shouldn’t be broken-open as it is. I believe the layman’s term for this condition is “shot to hell.”

I am not even going to try to explain how this component works or what went wrong, as the entire science of residential irrigation is beyond my ken. The sprinkler guy was assisted today by his son, who appeared to be about 12 years old. I asked the kid, “are you learning the trade this summer?” and he said he was. “It’s all really simple stuff,” he said nonchalantly. “None of this is hard.”

Well, shoot. I certainly thought it was hard.

What this kid doesn’t appreciate yet is that everything is easy for the one who knows how, and impossible for the one who does not.

Want to know more about the “simple stuff” of sprinklers? Check out this page that will tell you everything you didn’t know about how they work. I tried to read through it but my focus drifted away very early on. I’d love to have the kind of mind to which this sort of thing makes perfect sense; however, my talents lie elsewhere.

At least now I know how to turn my sprinkler system off, so that will be easy for me from now on.
