Pumps, Wells, Tanks, Controls / Re: Booster Pump

Yes, you can easily add a pump to boost the 44 PSI gravity supply to 60 PSI or whatever you want. But we would need to know the flow rate required by the "high flow" demands to size a pump.

Valve Tech / Re: Pressure between the pump and CSV

With the CSV1A adding additional back pressure it can make the pump think the well is deeper.  So, you should be fine as is.  But if you get a chance to change it the 1HP motor is fine, even with a 3/4HP pump end.  You could put a 10 GPM, 3/4HP pump on the 1HP motor, or replace the 10 GPM, 1HP pump end with a 15-18 GPM, 1HP pump end.

The back pressure to a Cycle Stop Valve is always whatever the pump can supply.  Looking at the curve for the 10 GPM, 1HP pump you mention it has a shut off head of 450'.  Subtracting the 40' for the static level leaves 410' or 177 PSI back pressure.  That is not too much for the CSV1A but is for the CSV125. 

That pump is really designed for a well with water at 200' or more.  The back pressure from the CSV is needed to keep that pump from upthrusting, as it is in a much shallower well than it was designed for.

A 15 or 20 GPM, 1HP would be better suited for a 40'-60' well and would only have 80-120 PSI back pressure.

If you have a tight fit and then tighten a union it can pull on the CSV.  If the pipe in the ditch after the CSV settles and drops, it can put the CSV in a bind by bending it.  The CSV1A is much stronger and impossible to plumb in a bind.  It is also much shorter and you would not have to double elbow around.  The CSV1A would just fit on the pipe before it goes underground.

Not much room outside the well.  To install it there you may need to go straight out a foot or so with the CSV, then double elbow back to the pipe going underground.  It the pump is set on plastic pipe you could also install the CSV125 in the well, just under the well seal.  If it is steel pipe you would need the SS version CSVS125.

Sorry. Couple of machines down so we all hands on deck until back on line. Try not to forget.

Here is a link to the parts break down.  Have to get my tech guy to find o-ring sizes.

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.

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.

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

« 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.

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

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

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.

Valve Tech / Re: Question on our CSV1A

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.

Sounds like the gauge is accurate. Bolt should not loosen on its own. But not having jam nut tight makes it easy for someone to mess with. If that is not the case the pump performance may have decreased a little. Spring would be only thing affecting set pressure as guts of valve either close or not If valve fails.  CSV fails,; pump cycles on/off not low pressure
