I have a question or concern. Any information will be appreciated and I'm thinking Valveman may offer some type hardware to help in my situation.
Issue: For the past 3 years, only ONCE during each summer irrigation season, one of 16 zones has failed to shut off water flow when the irrigation cycle completes. Then, when the next zone starts, there is too much demand on the pump to handle the additional water flow of two zones at the same time. Since I have a sand well, the pump evidently puts excessive strain on the well which causes excessive sediment to be stirred up. This in turn will cause my Vu-Flow filter to become partially plugged. When this occurs, the irrigation side of the filter is straining to get flow because of the filter being saturated with sediment. However, the pump side of the filter is not being affected and the pump is trying to satisfy the pressure switch and continues to pump water. In my case, the pressure switch is next to the captive air water tank underneath the house on the irrigation side of the Vu-Flow filter. Obviously, the pump will never be able to satisfy the pressure switch with the filter being partially plugged.
1- I am assuming that when this occurs, the pump may be building excessive pressure. Therefore, I have installed a pressure relief valve (set @ 75 PSI) to the pump side of the Vu-Flow filter. I already have one on the irrigation side of the filter. This measure should prevent a catastrophic pressure building event!
2- Is there a simple and possibly cheap piece of hardware that can be added to the existing irrigation system which will turn off power to the pump if pressure builds beyond a specific point?
3- Or, is there a better method to prevent some catastrophic pressure building event from occurring?
