Pumps, Wells, Tanks, Controls / Re: Formula for pump math?

Thank you for the information!

I understand about the pressure tank maybe being bad, that makes sense. When it cycles 3 times to fill a toilet, it runs 2 or 3 seconds each time and has things back up to 60psi. I thought that was okay since it builds up pressure so quickly. I do understand that short cycling will kill it. Do you think my pump is too small for the well depth? You said it barely makes enough pressure to work with 40/60, so that concerns me. I might have something incorrect in the system.
 
I was considering the CSV125 to thread into the bottom of the pitless adapter, but had another thought. Is there any reson i couldn't thread a pipe nipple into the pump outlet and put the csv125 there, then a hose barb to poly pipe? In my mind, that would keep the back pressure off the poly pipe and keep it in the pump housing. Or is that a bad idea?

I will consider all options and suggestions. Sometimes what we think we know about things isnt correct, and I am willing to relearn anything that I may have misunderstood for years. I will surely replace the pressure tank at this point. Just wondering if I did okay on pump choice and my thought process. If something I mentioned could be done better, I am all ears.

Awesome! That should work perfect. I’m thinking of ordering the 60 psi valve. Right now my pump switch is set for 40/60. I’m guessing that I’ll have to adjust it up to 65?

Just need to know how much pressure your pump can build.  Most 1/2HP, 10 GPM pump build 90 to 110 PSI max.  2.31' equals 1 PSI.  So, you can take off 10 PSI from having a static level of 25'.  It is not that your pump builds too much pressure, but barely build enough to work with a 40/60 switch.  Cycling 3 times to fill a toilet sounds like your tank is bad.  Get one of the PK1A kit with the 4.5 gallon size tank to replace what you have.  Everything in the PK1A is Stainless or plastic except the tank.  If you want to supply your own tank get the PK1ALT, which the LT means less tank.

Yes.  The CSVS125 can fit in the well just below the pitless adapter.  You can see it here.

Applications / In well csv

I’ve been looking at either converting my well pump to a vfd or installing a csv. The issue that I’m running in to is that my well supplies my house and my workshop and they are connected underground just outside the well casing. In order for the csv to work for me I believe I have to have it installed between the pump and the tee that joins the two water lines to the casing outlet. Is there a csv available that will fit in a 4” well casing?

First off, i am not a professional, so this is probably elementary for you guys that work with it everyday. But i was wondering how the math works to figure out your submersible pump pressure on the poly drop line. I want to get a CSV to install under my pitless adapter, but am concerned about the pressure. I just replaced my pump that went bad with a Simer 1/2hp 10gpm. My static water level is 25ft, my pump is 50ft down from the surface. What is the formula that figures the back pressure at 50ft of head?

Probably irrelevant details: 40/60 PS, 7 gal pressure tank. Poly line is 1 inch with no markings that i can find. Im sure its old. Probably cant take whatever its rated pressure used to be.

My current system cycles all the time, like 3 or 4 cycles for every toilet flush. Ridiculous. Im glad i found the CSV! I just need to make sure I know what I am doing before I order and install it.

One last thing, we have sulfur water in my area in Northwest Ohio. The water releases hydrogen sulfide gas which is murder on copper and brass. Kills electronics in my house all the time. Does the CSV contain copper or brass components?

I think it is going to depend on your pumping level.  From 60' deep that pump can only do about 8 GPM at 50 PSI.  When the pressure gets below 50 PSI the CSV just opens up like a piece of pipe and you are getting whatever your pump can deliver from whatever water level it is working with.  A gouge before the CSV would confirm this for you.

Thanks but I bypassed them with virtually no change in the flow.

I suspect the softener or filter.  Can you put them in bypass and try again?

HELP!  My system is a 78' well with a 1/2hp F&W 11GPM pump at 70'.  I have a CSVS125-1 installed in the well at the pitless adapter.  The pipe from the well to the manifold is 195' of 1-1/4" Pex.  Past the manifold is a Kinetico water softener system.  From there, there is a 1" poly pipe approx 50' to the 3/4" connection under my manufactured home.  The CSV is set for 50lbs and the pressure cut-off is at 40-60lbs.  I have checked the pressure at the hose bib in my shop (where the manifold and softener systems are) and it is 60psi.  The flow at the hose bib in the shop is about 6gpm. When I turn on the faucet to water the lawn, the pressure drops to 40psi or lower if any other water is being used.  This is a new home and I'm not sure where to start looking.  Maybe a bigger pump?  The wiring was installed to handle the amperage.  I'm open to all suggestions.
