Valve Tech / Pressure not maintained with multiple faucets open
« on: May 25, 2017, 12:15:09 PM »
I recently installed the pside-kick with a CSV1a in a new home. System worked flawless from installation.
About 2 weeks later I just happened to be next to the pump when it was running and noticed that it was short cycling and it appeared that on/off setting had changed from the preset 40-60psi to 30-50psi and varied around that for a period - all the while system on pressure maintained at 50psi regardless of the number of fixtures running. Concerned about the switch chatter I spoke with customer service and they walked me through an adjustment on the valve which seemed to straighten things out.
Day before yesterday, my wife was in the shower and after a couple of minutes the water stopped. I went to the basement and the pump was running but zero pressure on the gauge. I shut the pump off and closed the ball valve from storage. I reopened the valve and restarted the pump....pressure shot up to operational range. However, the pressure switch was very erratic and would not shut down the pump at 58-60psi. On inspection of the pressure switch the contacts appeared to be heavily charred. I replaced the pressure switch with a Square-D 40-60 switch with a low pressure shutoff feature. I completely disassembled and reassembled the system (I had a couple of small dribbles that were driving me nuts and wanted to make sure they weren't part of the problem) Fired the system back up and set the pressure switch to 40-60. Pump starts at 40psi, maintains 50psi pressure at 1 gpm (or so) flow but will not get to 60psi to shutoff. I had to lower the shutoff pressure to about 58psi for it to consistently function. From a response to an earlier post I tried to adjust the CSV stem for pressure with a higher flow (i.e. multiple fixtures operational). I'm not seeing the pressure response from that adjustment that I saw earlier when customer service walked me through the same operation.
I cannot find an viable explanation for no pressure condition as I have a constantly full 1000 gal storage tank 2 feet from the pump inlet, essentially force feeding it. The pump ran for about 90-120 seconds in this condition. My system is a Goulds JRS7 pump fed from a local storage tank. The only thing between the tank and inlet is an 1.25" ball valve. I have a 1" check valve on the pressure side of the pump at the input of the CSV. I've attached a photo of the system.
Thanks for your advice and I also have to say that I find it very cool that the guy that is answering these posts is the same guy that invented, manufactures and supports the product. Can't get a much shorter path to the real info than that!
