Pumps, Wells, Tanks, Controls / Re: CSV1A

« on: September 26, 2014, 03:19:11 PM »

Am I correct in assuming that:

CSV1A screw turned counterclockwise (loosened) = decrease constant run pressure?

CSV1A screw turned clockwise (tightened) = increase constant run pressure?

What does the adjustment screw on the CSV1A adjust and what is the procedure to adjust it?

The pump is a brand new Goulds (18SB15422C) 18GPM 1.5 HP 4" Submersible Water Well Pump

I closed everything above the CSV1A and the pressure switch except for the 3/4" line to the hose bib. I did a bucket test and all I can get is about 5 gpm at 10 psi.

The well has plenty of water and instantly returns the system to 83 psi when I close off the hose bib. Any ideas?

Edit ==================================================================================================================

OK I just closed the CSV1A adjustment screw by two turns and I got the full 16-18 gpm at 75psi from the hose bib. Now it is like a fire hose with huge pressure and flow.

What does the adjustment screw on the CSV1A adjust.

How do I know when the adjustment is correct? I can't seem to get a handle on where to set the screw.

Pumps, Wells, Tanks, Controls / Final Adjustments

OK... I have installed my CSV1A.

I have installed a 60/80 pressure switch and a 6 gallon pressure tank pre-charged at 55psi.

The CSV1A is installed on the main line coming from the well pump, which is a 1.5hp/18gpm unit.

The well has a static head of about 45 ft.   The well has a tremendous recovery rate so the low static head is not a limiting factor.

The pressure switch is installed in one of the side ports on the CSV1A.

The pressure tank is installed downstream about 5 feet from CSV1A.

Starting pressure is 84psi.

When I turn on a bathtub, the pressure drops from the 84psi to about 62psi where the pump turns on.

The pressure slowly builds back up to about 70psi and holds there.

If I add a sink faucet the pressure holds at about 68psi and holds.

If I add an exterior hose bib to the mix the pressure immediately drops to about 3 psi.

Is this what I should expect from the system or I am doing something wrong?

Is my pressure tank too far from my pressure switch?

The instructions say to “adjust your demand to 2-3 gpm”… do I control the demand by modulating the main valve downstream from the pressure switch?

The reason I have installed the 60/80 pressure switch and the CSV1A is to try to overcome the pressure drop through the tandem Big Blue sediment filters (a five micron followed by a 1 micron at 20” x 4.5” each). The pressure drop across the filters is about 30 psi so it really plays havoc with the system pressure.

I still don’t seem to be getting the pressure and flow that I had hoped for and would appreciate any input on this matter.

I am still somewhat confused about heat dissipation at the pump.

When the pump has cycled of (60/80 sys with CSV1A) and the pressure is around 80 t 85 psi. A 6 gal tank should be holding about 1 gallon?

If someone, a child for instance, turns on a faucet for only a few seconds, just enough time to kick on the pump, the pump will only stay on for the time it takes to replenish. Now the child decides to do that over and over and over again… doesn’t that pose a risk of overheating of the pump?

It seems as if you could turn the pump on and off at any faucet location, just by running the water a few seconds at a time?

Thanks,

The tank I am getting says it has a capacity of 6 gallons with a 5.5 gallon draw down. From your comments then, I should assume that this 5.5 gal draw down, that they advertise, is calculated at only one atmosphere?

The one gallon draw down will be fine. If we ever get to a situation where we have no power for an extended period of time, I will just pull the well and drop a bucket down on a rope. ?

What would be the consequences of installing a 60/80 pressure switch with a CVS150?

My new pump is a 1.5hp Goulds, that can pump up to 18gpm.
I only have a about a 45’ static head but it is in an 8” pipe, which gives me about 100 gallons of water in the column above the pump.

The well has a tremendous recovery rate so I’m pretty sure we will be ok with a pump this big. (If not then I will install a CSV CS1PH1-2HP230V pump sensor).
The reason I went this bit is that we have a lot of back pressure coming from the house; i.e. three and a half bathrooms, with 3 deep soaker jetted tubs, a Rheem tankless water heater and a tandem “Big Blue” filter system, hosting a 5 micron and then a 1 micron filter (I may also add a carbon filter in a third big blue housing). I ran 1” copper feed lines and ¾” branch lines throughout.   

As of right now I will be installing a CSV1A, a 6 gallon pressure tank with a 5.5 gallon draw down and a 60/80 pressure switch. If I have any problems with water supply I will install a CSV CS1PH1-2HP230V pump sensor.

Do you see and holes in my planned installation?

Thanks,

Leonard

Thanks again for all your help,
I don't know how it got into ether but I am not particularly concerned about residual water being left in the tank. If I did I didn't mean to imply that... sorry.
I am considering purchasing a CSV1W to replace my CSV1. What are the benefits of using the CSV1W instead of the CSV1 in a 60/80 system?
What are the different applications for the CSV140 the CSV150 and the CSV160, and which one would be needed in a 60/80 system?
Also… is there a significant functional difference between a tank with a drawdown of 3.2 gal vs one with a drawdown of 5.5 gal, other than the residual water in case of power failure thing (witch I don’t care about)?

Pumps, Wells, Tanks, Controls / Well pipe crud

« on: September 15, 2014, 04:41:58 PM »

I am currently replacing my dead well pump and can see that there is a significant amount of wet crud on the inside of the well pipe.
Is this crud damaging and is there any way of resolving the problem without replacing the pipe?

Wow!
Thanks for responding.
Not to be argumentative but since I first asked this question, I found somewhere on this forum (I think), that the tank pressure should be set 2 psi below the pressure switch cut in pressure?
So that would require the tank pressure to be set at 58 for a 60/80 system... again I am not trying to be argumentative here… just want to make sure I am understanding correctly.
I have been using a CSV1 for the last 8 years and it is truly manna from heaven. I have been running it with a tank preset at 45psi and tank draw down of 5 gallons with a pressure switch set at 50/70.
Will a CSV150 work with a 60/80 system pressure
What are the different applications for the CSV140 the CSV150 and the CSV160?
My other question was... is there a significant functional difference between a tank with a drawdown of 3.2 gal vs one with a drawdown of 5.5 gal.
Are there any, out of the ordinary, tank specifications when using tanks with a Cycle Stop Valve; i.e. using a tank that is used with a reverse osmosis system
Do you know if Cycle Stop Inc. sells their small pressure tank individually?
That’s a lot of questions sorry.

« on: September 12, 2014, 10:40:16 PM »

What about pump heat dissipation if there are many very short cycles during the day?

For most single residential applications is there much difference in outcome between using a tank with a draw down of 3.2 gallons vs a tank with a draw down of 5.5 gallons?

Most of the available small 3,4,5 6 gallon tanks come with a very low preset pressure. I have one of these tanks and use it with my CSV1. I increased the preset to 45 lbs and it seemed to work well... what would you suggest I set the tank pressure to? I would like to run my system at 60psi to 80psi. Any suggestions would be welcome.

Thanks,
