CSV for dairy with multiple wells

[cnymaplehurst]

Good Afternoon,
I'm looking at buying a pair of CSVS125-1 valves for the wells on our dairy farm and want to make sure that my plan for them is correct and that issues with our wells aren't going to cause any problems with the CSVs.

We have two wells about 60 feet deep with 4" submersible pumps (2 HP and 1.5 HP) with a pressure switch for each pump.  The wells are about 200 feet from each other and both produce water that is high in iron and both have been contaminated with iron eating bacteria that we control with chlorine pellet well chlorinators.  Both wells also have fine sand in the water which we filter out before the water goes into the barn water system with an 86 gallon fiberglass Wellmate bladder tank.

My plan is to put a 60 PSI CSVS125-1 on the 1.5 HP pump and set the pressure switch for it to 65/45 and then put a 50 PSI CSVS125-1 on the 2 HP pump with the pressure switch set for 55/35.  Is this an appropriate plan and will the chlorinators and sand cause any issues with the CSV?

Regards,
Nate

Sounds like a good plan.  But the CSC125 is the only valve we have that doesn't like iron or dirty water.  It will work, it just probably won't be long before they start leaking.  If these are less than 20 GPM pumps, the CSV1A is best.  But if they are 25 GPM or more the CSV3A2T would be needed.
