|They are Back!|
|Murph mowing greens for second time this week|
With an 81 year old irrigation system that has main lines about 6 feet deep there are bound to be issues right? One of the main issues is that we drain really well and if there is a small leak we never know where it is. We have a small submersible pump in a small well that maintains the pressure in the system, 115 psi for those interested. For context the pressure on municipal water supply to your residence is 40-70 psi. We live and die by the cycle of this pressure maintenance pump (pm pump, or pm cycle). It tells us how tight the system is and whether or not we have any leaks and how bad. The pumps have settings for major blow outs and will hopefully shut down before doing extreme damage to the ground around the break but for smaller leaks they do not know the difference between that and us watering. Hence the reliance on the pm cycle. Historically we start the season in the high 20's and eventually settle out in the mid teens. Murph and I look at this cycle constantly. It is usually the first thing I do when I wake up, checking the irrigation system to see what kind of day I will be in for. We live every day waiting for failure due to the age of the system.
I can honestly say this is the most excited I have been for a leak
Well, last Fall the pm cycle dropped to 4 minutes for weeks on end. We drove around and around looking for weepy heads and leaking pipes to no avail. We came up with a plan to open the system in small stages hoping to pinpoint the leak. This never really came to fruition since a couple of the fairway valves would not hold and filled with water against our best efforts. The newer system from the 90's is plastic and really the worst part of our system or the part that gives us the most trouble. The glued joints on this system are starting to fail and there are literally thousands of them so our worry was that maybe we do not have one big break on abandoned galvanized pipe down deep but many small leaks on plastic all over. After 4 days of tinkering with the system partially filled up, at an increased pressure of 120, the leak finally improved enough to show itself. I can honestly say this is the most excited I have been for a leak. At least I can stop worrying about where and when and whether the pm pump is going to burn up from such a short cycle.
With a big storm predicted for today and tomorrow the sunrise was really good. Cheryl took these above. Mine are below and were too early and I was already off to work when it peaked.
