I'll put them in the water lines just outside the pitless adapters and make covers for them out of 6 or 8 inch schedule 40 PVC so that they can be buried without being in direct contact with soil.

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.

Industrial / CSV for dairy with multiple wells
« Last post by cnymaplehurst on March 03, 2026, 03:01:49 PM »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

Pumps, Wells, Tanks, Controls / Re: Determining back pressure with Psidekick
« Last post by Cary Austin on February 23, 2026, 08:20:39 AM »Thanks for the confirmation. Figuring the back pressure from a CSV is fairly easy. Subtract the static water level from the pumps shut off head and divide by 2.31.

« Last post by Thronk on February 16, 2026, 05:56:47 PM »Okay thanks. I decided to throw on a pressure gauge while installing because I hated not knowing for certain and it does in fact sit at 97 PSI! Quite surprised to be honest, I figured there would be losses somewhere to the CSV but here’s to more validation for you!
Thanks again, so far it works great.

« Last post by Cary Austin on February 15, 2026, 09:34:40 AM »The burst pressure of pipe and fittings is 2 to 5 times the rated pressure. So, no I am not worried about it. Actually the back pressure from the CSV is easier on the pipe and fittings than without a CSV when the pump is cycling on/off and causing water hammer.

« Last post by Cary Austin on February 12, 2026, 07:07:07 PM »That is actually a pretty good well record. It shows a 7 GPM, 3/4HP with a static of 175'. 100 PSI pipe is very low rated pipe but, I calculate the back pressure at only 97 PSI.

Pumps, Wells, Tanks, Controls / Determining back pressure with Psidekick
« Last post by Thronk on February 11, 2026, 08:48:44 PM »I purchased the psidekick based off my well report (not installed yet), seems like it meets the parameters allowed as long as I understood my report.
Now I didn’t think about back pressure and the piping/fittings I have and whether the rating is exceeded. Can I determine back pressure with the information in my report? I started to get concerned since the brass barbed fitting I’m going to use in the black underground cresline pipe is rated for 100 PSI. Will try to see if I can make out the cresline rating on the pipe.
Appreciate any help in advance.
Edit: incoming supply pipe is 100 PSI rated as well, can’t find specs on the pump, not under the well cap. Installed in 1990, location is Maryland.
