I live in central Oklahoma and we bought a 40 year old house which depends on well water. In 2017 the pump was serviced and a new pressure tank, pump controller, and pressure switch were installed. In March of 2019 we had sprinklers installed, 6 zones in all with 6 heads on most zones. 3 months ago I had to replace the pressure switch (contacts were burnt up), yesterday I replaced the pump controller (bad start capacitor), and today realized the bladder in our pressure tank has busted... fun.
In my research as to WHY all of this has happened I came across several articles and discussions and it all boils down to the pump cycling on/off too frequently. In my case, when the sprinklers are on the pump cycles anywhere between 45 and 90 seconds depending on which sprinkler zone is on. I realize having a busted bladder is going to impact the cut in/out times, but I don't know how much of an impact it will have when watering the lawn. I figured that is more about stuff in the house like faucets, toilets, etc... since sprinklers will burn through 20 gallons of drawdown (80 gallon WF-23) in no time.
From what I've read the, sprinklers should be right-sized so the well pump runs continuously while they are on. This means that each zone should have the same output in gpm as the well pump. Does that sound right? If so, should the company who installed my sprinkler system have known that? I'm not looking to recoup any sort of payment from them for the broken well components, or my time to fix them. I'm simply curious if this type of thing is something they should have accounted for. If so, I'll likely ask them to come right-size the sprinklers so once I get this bladder fixed I can feel comfortable running my sprinklers without ruining my well pump and other components.
Also, I have read about Cycle Stop Valves and I'm considering installing one to help with all of this. It's just a bit complicated since they spliced the sprinklers into the main line before it goes into the house. Apparently I must install the CSV before that split... not sure how I'll achieve that just yet.
Thanks in advance for any help or advice!
