What a difference a couple of days make! We were bemoaning the problems we had with a busted irrigation system just a couple of days ago and today the problem is non-existent. Our landscape contractor found the time to come here and fix our woes this week instead of what we thought would be a delay of unknown length. They quickly diagnosed the problems, made the changes and this evening, all is working again.

Of course, the fixes weren’t all as simple as I make them sound in the first paragraph. They actually spent considerable time cleaning up the area behind the RV drive where our “Rosemary Farm” is growing – or maybe overgrowing. In the composite image above, you can see the after cleanup of the back area – I could look in the photo archives to find a before picture, but I’m too lazy this evening. 😉

I forget the exact number of one gallon rosemary shrubs they originally planted back there, but it was over fifty and under a hundred. Each one with a watering tube of its own from the irrigation feed line planted on the hill just above the shrubs. After the cleanup as shown, the crew installed an all new main line and “spaghetti” feeders for each shrub. This time, the feeders are short and they extended the larger diameter feed line for each group of two or three shrubs. We tested it this afternoon and it looks like everybody is getting the water they need in our arid climate.

The first thing they fixed (yesterday) was the leak shown in our previous post about the problem. They also replaced one of two electrically-controlled valves that activate the two main feeder lines according to the program set up in the controller. Both the leak and the valve malfunction contributed to the excessive water usage we have been experiencing.

We are still in the process of doing some other work with the landscapers; there is another area we want to have irrigated where we acquired a nice ocotillo after the fact. There is also some overdue rock and cactus garden maintenance they are willing to do while they are available. We should be in pretty good shape after they’re done with that and won’t need to do any of that for ourselves until after the weather cools down a bit.

Since May or June, we have noticed an increase in water consumption on the monthly bill from the Town. At first, I thought it was because we had filled the spa for the summer, but then the increased consumption continued. In July, I found that the circuit breaker to the water system had tripped after having some of the shrubs appear to wither. I got that fixed and then the increased consumption resumed.

Yesterday, I finally contacted the landscapers that installed the irrigation system here. Together, the foreman and I discovered that a continuous water flow was occurring in an unknown location around the property. We also discovered a flow (pictured above) that ran during the active time for the irrigation to flow. Both problems, the one we can see and another somewhere stop when we cut off the main irrigation valve.

After discussing the problem with the landscaper and probable solutions, it would seem we’re in for a complete overhaul and replacement of much of the system. Chronically, in the desert, systems that use PVC tubing seem to need replacement at eight-to-ten year intervals, which is exactly how old the system is.

So, for the time being, we’re going to have to water the shrubs and trees manually since the irrigation valve is closed pending fixing things. Our landscaper has a number of other jobs ahead of us and it will be a week to a month before we can get back to normal.

For reference, the leak pictured above (the one we can see) is located between the ocotillo and the courtyard wall in front of the walkway to the courtyard gate. The irrigation lines and all are controlled from near the corner of the garage. Click on either image to enlarge.
