Frequently Asked Questions / Re: Will any existing well pump work with a CSV or do I need a special pump?
« Last post by Cary Austin on June 26, 2024, 12:36:32 PM »
The CSV was designed to work with a standard full speed pump to replace those expensive, troublesome, and short lived VFD or variable speed drives.  Actually most variable frequency controls also work with a standard pump.  There is really nothing different about the pumps.  Just the expensive VFD controller makes a good pump give troubles and not last very long.

Do I need a pump that would be able to change frequencies or is a standard well pump ok to use with a CSV?

Turn the pressure switch up first. With switch shutting off at 80 you can just tighten CSV adjustment until it holds 70.

Valve Tech / Adding more pressure to current installed cycle stop valve

Hello, I have had a csv for about 8 years. Just switched out a bad pressure tank(10gal). The CVS holds pressure around 60psi shuts down at 70 psi and cuts off at 40psi. I was considering bumping the pressure up a few psi
For more pressure in shower on 2nd floor.
Do I need to start from the beginning,  (back out adjusting stud out all the way) or can I just turn it from where it is until I get a few psi increase .
Thanks for any help.

Glad you are happy again.  Didn't think the bolt would work loose on its own, but will recommend tightening the jam nut from now on.  Thanks.

Just a quick follow-up. The CSV held properly today at 44 psi as set.
Only guess I have is I did not tighten the lock nut.
Thanks again.

Appreciate your time.
I'll now monitor how the CSV functions while the shower is being used and see if my adjustment holds.
I'm positive that I'm the only one messing up the plumbing here.

never seen a spring lose tension over time unless they get rusty or break.  At least for 30 years as the ones I set 30 years ago have never needed readjustment.  However, if the diaphragm tears or leaks and the spring gets wet, it can lose tension and/or break.  But normally you would notice water leaking from around the adjustment bolt and the CSV no longer functioning long before the spring got rusty or broke. 

Even a slight change in pump performance should have no effect on the CSV setting.  It is just not normal for the setting of the CSV to change unless someone messes with the bolt.  Without the jam nut tight, just a slight bump on the adjustment bolt can make a big change as one full turn is like 14 PSI difference.

Sorry for your problem, but I don't think there is anything to fix.  If it changes again let me know and we will do whatever we can to remedy the issue.
