Pumps, Wells, Tanks, Controls / Re: What type of CSV should I use for each pump and how should I set them up?

« on: April 10, 2014, 01:40:12 PM »

Spring has come and now the rush is on to complete this project.  Please excuse the long delay.

I have some questions. 

1.  There is a difference in elevation of 10 feet between the 2 setups.  Will the 4.33 of PSI of pressure difference between the two pressure switches affect the setup?  My guess is yes.  With the CSV and pressure switches set up with only off 5 PSI of difference in your calculations, and the difference in elevation are we back to equal?

Note:  The 3HP Pump setup is 10 feet below the 5hp pump setup.

2.  If I understand correctly, the reason to make the 3HP as the primary pump is for its ability to handle the lower flow demand.  I completely agree with this approach.

3.  Can the CSV be mounted in a verticle fashion or is the valve required to be mounted horizontally.  I ask this because of space concerns in the well "rock"

4.  Will I be able to tweak the valve little by little to get the exact desired results or does the valve only adjust in increments of 5psi.  I think this question relates to question #1

Cary,  I also wanted to thank you for all the help you have given me.  I have learned a lot reading your posts here and elsewhere.

No,  I do not know the pumping level in the well.

 It would be possible to put the valve at the well head with some reconfiguration of the plumbing.  Well #1 is the one without the diaphram tank in the picture.  The green electrical tape in this picture identifies the line to pressure tank and control box.  As you can see there is not much room between the well head and the Tee.  The brass check valve is hogging all the real estate here.

 Well Pump #2 is the one with the blue tank.  In the picture of well pump #2 I put  two stripes of green electrical tape where I think the CSV can go.  That is assuming that it can me oriented in a verticle fashion.  Does a CSV have to be mounted horizontal?

Here is the set up.  Two separate well and pump systems both feeding pressure to one large underground network of 2” PVC pipe with 15+ yard hydrants and a 60 zone computer controlled irrigation system.  We are experiencing the problem of going through pumps on well # 1 rather quickly in my opinion.  The 33GS50 in the well now is shot I think.  It is the 4th pump since 2003.  I am not interested in diagnosing the broken pump in the well but more interested in coming up with a better solution to our setup.  I believe the pump is killing itself cycling on and off during the medium usage.

Our water usage is medium to high.  It is not uncommon for 1-4 hydrants to be on all day in the summer.  One hydrant can be 5-7gpm.  4 or 5 hydrants is usually the tipping point of pressure loss  The irrigation runs in the evening for a couple hours with water usage in the 1-30 gpm range.

The pump in well #1 is set as primary.  The pressure readings below are what I observed on the guage during cycling.

I also have a question as to placement of CSV in Well #1.  Because the pipe Tee's out of the well , left goes to the pressure tank and dead ends..... right goes to the filters and end usage.  My guess is because the water flow on the left side is bidirectional the CSV can not go there.  And now that I am thinking about it the water may be bidirectional through the right side from time to time when Well pump # 1 is offline and pump 2 pushes water into diaphram tank 1.
