Valve Tech / Re: CSV125 Leaking When Power Goes Off
« Last post by Cary Austin on Today at 07:39:16 AM »
The CSV125 uses an o-ring seal.  It takes pressure to push the o-ring into the crack and stop the leak.  Usually doesn't leak when the power is off unless there is backflow causing a vacuum in the CSV.

Valve Tech / CSV125 Leaking When Power Goes Off
« Last post by bajanboy on September 25, 2020, 05:40:28 PM »
Hi what would cause a CSV125 to start leaking water if there is a  power outage and  the pressure tank goes empty ??
there was a power outtage and the pressure tank ran out of water and I found water coming from the CSV125,
what would cause this to happen??
Once the pump starts back working the CSV stops leaking water...

I don't know how it is working at all?  Here is a link to the curve for that pump.

https://littlegiant.com/media/130644/995258.pdf

It only make 125' of head, which is 54 PSI max.  No way it is making a 40/60 switch and shutting off the pump.  Looks like that pump will still do about 25 GPM at 50 PSI even though it maxes out at 54 PSI.  You won't need a 2HP jet pump.  A 1.5HP jet pump like a Goulds J15S will pump a lot more water than that pump at 50 PSI and has a mx pressure of 80 PSI, so it works great with a 40/60 switch and will shut off as needed.

Thanks!  My local irrigation supply house set me up with my current pump/ cycle stop configuration and it has worked for years except for the occasional times that it doesn’t :). I think my pump must be making close to 70 psi when everything is perfect.  The pump is Franklin electric end suction centrifugal pump model cp-200-c , 3400 Rpm’s, 230 volt, 2 horse.  So I need to replace it with a 2horse jet pump?  Thanks for your help.  Jon

Well your well maybe 400' deep and the water level is at the surface or even flowing, but a shallow well jet can still only access water from 24' deep or less.  If the water level is pulling down to 24', the pump is running out of water.  Could also be a suction leak, but usually won't build back up to 50 after losing prime from a leak.  Can you check the water level in the well when the pressure is low?

I don’t Know Cary. My well is over 400 deep into the Floridan Aquifer. The well flows with enough pressure without a pump  to shower downstairs. The  pump was new when I installed the CSV, so hopefully it’s ok. If there is not enough water, wouldn’t the pump cavitate or make an odd noise. The pump is running smooth. I’m hoping for an education.

Below 40 PSI a 40 PSI Cycle Stop Valve is wide open like a piece of pipe.  If the pressure is dropping to 28 PSI either the pump is not producing as much as it should or the well depth and volume are not adequate.  Sounds like a drop in the water level?

You need a jet pump.  Sprinklers pumps don't build enough pressure to work with a pressure switch and/or CSV.  Well, they will work with like a 30 PSI CSV and a 20/40 switch as those pumps usually have a max pressure of 42-52 PSI.  Water gets hot when running a pump too close to its max pressure.  To use a CSV125 in 50 PSI, you need a 40/60 pressure switch and a pump that has a max pressure of at least 70 PSI.  Even then you need the 50-3 instead of the 50-1 to get enough flow through the CSV to keep the pump cool.

My 2hp Irrigation pump seems to work fine for months at a time then randomly it will not turn off when no valves are open.  This will cause the water in the pump to heat to the point the pvc pipes separate from galvanized pipes going in and out of pump (2.5’ from pump).  Any help would be appreciated. Pump 2 horse, small 15”x15” +- pressure tank, 40/60 pressure switch,  1.25/50 cycle stop. Thanks, Jon
