Looking to installe CSV

[Brandymax]

No I cant.... I am wondering if something on my system is blocking it.. it should though

[Cary Austin]

Maybe a popup blocker?

[Brandymax]

I checked that..... will keep trying... stuff like this drives me nuts.

[Cary Austin]

I would remove that swing check.  You must have one in the well or you would be getting a lot of air and water hammer.  If that swing check isn't causing a problem now, it is only a matter of time.

[Brandymax]

ok.... everything works good now, I will remove and see how things go, can always reinstall. Have no idea why he would put two in, but I will go with your advice.

How big of an issue is it using the large pressure tank I have now?

[Cary Austin]

The big tank is not an issue.  Just need to set the CSV close to the pressure switch off setting so it doens't take more tan 3 minutes to fill the tank after all water has been turned off.

[Brandymax]

ok.. the valve is on the way... I am sure I am going to need some help ... or maybe not 

[Cary Austin]

Just make sure the pump runs and the pressure holds steady while running something small like a shower.  Then make sure it doesn't take more than three minutes to fill the tank after you turn off all the water.  If it does that you don't need me.  If it doesn't call or click here and I will be glad to help.

Thank you Cary
I will post either way

Your help has been appreciated

Hello Cary,

Well I am back. Got the CSV installed.
have the pressure switch set at rough 45/65... +/-
Right now I have CSV around 60 ish
If I turn on 1 faucet the pressure with go down to 45, climb back up to the 60 and stay constant, but if I open another faucet the pressure slowly drops down again, if I open another drops even further (it doesn't hold steady). If I shut 1 faucet off it climbs back up a little, shut another it climbs back up to 60. When I shut all faucets, it goes from 60 to 65 with in 30 seconds. Am I asking to much of the pump at this pressure?

You only have a 7 GPM pump.  At that depth and pressure, that pump should be able to keep the pressure up to 60 PSI, as long as you are using less than 6 GPM.  At 6 GPM, the pressure from the CSV1A should only be 3 PSI lower than when running 2 GPM, which is still 57 PSI. You can see the 3 PSI loss in the "Reduced Pressure Fall-off" chart at this link.

Any pressure lower than 57 PSI, is because that is all the water your pump can supply.

If you ever have to replace the pump, you could go with a larger pump.  That CSV1A is good to 25 GPM.  Even if your well can't produce more than 7 GPM for long periods of time, it probably can for short periods of time.  Then the CSV can make it work like a 7 GPM pump again when you need to use water for a long preiod of time.  You simply open only 7 GPM from the faucets, and the CSV can make a 25 GPM pump work fine at 7 or less GPM.

Hello Cary.....
So, if I am understand you correctly... By me opening all of the faucets I exceeded the 6 gpm demand big time. ( I doubt that will ever happen , I was just seeing if I had the valve installed correctly) I had a shower, tube, and outside faucet open .

That is what cause the pressure to drop way down? The pump couldn't keep up with the demand?

Would you happen to know, or tell me where I could find out how many psi are between the pump and the CSV ? I have a chlorinator and since I have increased the tank pressure I seem to be pushing water back thru the stenner into the tank , I am guessing the injection check valve is weak or not big enough.

Thanks for the reply

[Cary Austin]

Yeah those three things will put out more water than your pump can produce and the pressure will fall off.  The pressure before the CSV depends on the pump and the water level in the well.  If the water level is high, like at the surface, that pump can build 225 PSI.  If the water level is at 200', then you will only see 138 PSI before the CSV.  Either way you want the chlorinator, filters, and any water outlets after the CSV, and they will only see the 40/60 pressure.

[Brandymax]

Ok.. well now that throws a curve ball at me...LOL
I am going to have to cap the mixer thing that the injector is installed in. Then come up with a way to install after the pressure tank. See , you do one thing and it leads to another and another and another... the joys of being a DIY'er

Cary,
I am curious why this didn't happen before, has install the CSV increased the pressure between the valve and the pump?
