Valve Tech / Re: Detailed dimensions of all o-rings in the CSV1A valve

« Last post by Cary Austin on July 09, 2024, 07:08:16 PM »

Sorry for your problem. But that is the first time in 30+ years that an o-ring has been the cause of a CSV failure. Like you saw it smashed in when it was too big, it is squeezed into a slot and should nor be able to move, break, or get out in anyway.  We buy them from a local bearing and seal company right off the shelf.  See if I can look it up. But would have been posted years ago if there had been a problem.

Valve Tech / Detailed dimensions of all o-rings in the CSV1A valve

« Last post by pzinser on July 09, 2024, 12:14:52 PM »

I encountered a torn o-ring (the smaller one just below the “windows” in the plastic).  I could not find any details on exactly what size o-ring is needed.

Apparently, it would be ideal to have the outside diameter, OD, inside diameter, ID, and cross-sectional dimension, CS. (See attached image)

I measured the torn o-ring, and then discovered absolutely no one (5 shops visited) in town had that size.  I know I can order them from CSV (and they actually DID put some in the mail to me which I TRULY APPRECIATE) but I really needed an immediate solution because my pump was cycling in 20 second increments every time the 4.4 gal tank “dumped”.  No one locally carries a 1/16” thickness (CS or cross-section) ring, which I believe is what’s needed.  The “thicker” rings that everyone seemed to have will not allow the red valve housing to seat all the way, and thus it leaks continuously.
 I wound up taking a scalpel to the closest-sized one I could find to “thin” it down – I could not believe that this worked (for now) because the result was so ragged, but I never want to do it again.   

Long story short, could someone post the EXACT dimensions on ALL the o-rings in this valve. With this info. I’m hoping I can get someone locally to stock them for emergencies.

Thank for your help!

The 10SQ05-160 can only make about 95 PSI max.  If it is really 40' down to water don't set the pressure switch any higher than 40/60, as that is about all the pump can do.

I’m supposed to receive my CSV-125 this week. I looked up the spec on my well pump and it states that it has a max operating pressure of 217 psi. I have a grundfos 10SQE05-160 well pump that is pushing about 40 ft of head pressure. What would you recommend to ensure I don’t over pressure the csv?

I was also looking at the pressure rating on my well pipe and I think the poly pipe is only rated for 100 psi. What do you recommend for plumbing pipie from the pump to the csv?

Frequently Asked Questions / Re: Will any existing well pump work with a CSV or do I need a special pump?

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

« Last post by Crazywade on May 30, 2024, 01:27:39 PM »

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.

Valve Tech / Re: Question on our CSV1A

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.
