Valve Tech / Which is better?. CSV125 valve In well or OUT of well?.

« on: May 23, 2021, 07:27:39 PM »

Currently I have a CSV125 valve located in my Pump House just BEFORE the Pressure Tank and my BACK PRESSURE reading is 170 psi!. I was wondering if I put the valve IN the well say half way down at 50' would that REDUCE my BACK PRESSURE?. My total depth is 100' and I have 1" Poly Pipe rated at 200 psi. with a 1/2 hp motor. As I read the MAX Back pressure for the CSV125 is 150psi. If I read and understood Cary Austin in one of his previous post he explained that every 2.31' of depth in the ground their is a LOSS of 1psi. So if I put my CSV125 at 50' I should see a LOSS of 21.66 psi?. So 170-21.66=148.35 psi?. Did I get my math right?. That would put my BACK PRESSURE at 148 psi, below the MAX rating of the CSV125 valve of 150 psi, Right?.

ROFLMAO! Not familiar with that term?. So would you say I should continue with the CSV-125 that I have on my system?. I really miss that constant water pressure!.

Applications / Back Pressure from CSV-125

Has anyone been experiencing massive BACK PRESSURE while using a CSV-125?. I installed one on my system and jump from 70 psi to 170 psi with a 1/2 hp deep well pump 100' down using 100 psi 1" Poly pipe!. Had no problems but a Well Pump and Tank person suggested I take that CSV valve off immediately and I could go to his house and see his VFD set up and he gets constant water pressure w/o excessive BACK PRESSURE and his VFD protects his system from several problems that come with constant pressure system.
I like the CSV valve and the constant 50 psi I was experiencing but that 170 psi BACK PRESSURE scares me now that I was made aware the problems I was looking at. So far I have been very lucky I didn't have a BURST PIPE or DAMAGED PUMP.
Anyway to adjust that BACK PRESSURE on the CSV-125 valve?.
