New Pump System

[Cary Austin]

That pump will still work fine at 40/60 pressure.  At 10' lift and 50 PSI it delivers about 15 GPM, which should be plenty.

[Mikerf12]

Will that pump work with the 50/70 pressure setup i bought from you?

[Cary Austin]

From 10' of lift the J10S will do 8.6 GPM at 60 PSI, and has a max pressure of 72 PSI.  This means you would be able to turn the pressure switch up to about 45/65 and use a 55 PSI setting for the CSV. 

If the well is large enough diameter to install a submersible, you can get a lot more flow and pressure for less money.  A 1HP, 33 GPM Hallmark will give you as much flow and pressure as you want, and I see it on line for about 150 bucks.

so without any modifications to the setup it will work if the Max pressure of the pump is 72psi?

The chart has depth to water on the left side.

Cary,

Thanks for all your help.  The pump purchase is that last piece of the puzzle for me.  I’m not trying to be a pain here but have a relatively limited understanding of well pumps and am excited to use the cycle stop system.  I really don’t want to go through the effort of installing the submersible pump at this point.  Given all of the factors I have provided here (3 bedroom two bath house, acid neutralizer and softener and a lawn irrigation system).  What would be the best shallow well jet pump to work with the equipment I have purchased from cycle stop valves?

[Cary Austin]

Without using a submersible, the J15S is best, but also the most expensive.   

[Mikerf12]

Cary- given my application, which submersible pump would you recommend?  I still have not ordered and am hobbling by with the old pump.

[Cary Austin]

The depth is listed as "total suction lift" on the chart.  The J10S shows to build 72 PSI max, pump 15.8 GPM at 50 PSI, when lifting from 10' deep.  That should be plenty of water.  And the CSV will make it work all the way down to 1 GPM as needed.

[Mikerf12]

Is there a J10s submersible model? If not is there a submersible brand and model you recommend? Just trying to look at all options before I pull the trigger.  Thinking it may make sense to go this route since I need to go into the well anyway. 

[Cary Austin]

Any 10 GPM, 3/4HP submersible will do as much as the 1HP jet pump.  However, for a booster pump or really shallow well there is a 1HP, 33GPM Hallmark on the Internet for 130 bucks.  You could buy 3-4 of those for what a 10 GPM, 3/4HP will cost.

[Mikerf12]

Cary.

Installed your setup last weekend using the hallmark 1 hp submersible pump you recommended, pump is about 10’ down.  Quick question is there a way to get more pressure out of the csv?  When I open my sprinkler zone the gauge on the csv is holding steady at 45 psi.  Is this a limitation of the pump of is there an adjustment I’m missing on the csv?

Thanks,

Mike

You can turn up the CSV1A as high as needed.  But you will need to turn up the pressure switch as well.  If you want 10 PSI more pressure on the sprinklers, then set the CSV and pressure switch 10 PSI higher than they are now.

[Mikerf12]

Cary

Low end of pressure switch looks to be about 50 and high end just over 70.  Can I adjust the csv to 60 with these settings on the pressure switch? Also is there literature on the csv adjustments somewhere?

[Cary Austin]

Sure.  Just run a shower or something at about 3 GPM and adjust the CSV1A to hold 60 as you want.
