Thank you for the answer.  I misinterpreted the pump specs.

Thanks,

Pumps, Wells, Tanks, Controls / Pump runs continuously :: Unable to reach cut-out pressure.

« on: March 31, 2019, 10:07:04 AM »

Hi -

I have a CSV and pump newly installed as described below.  The pressure never gets high enough to turn off the pump.  IE - the pressure never reaches the cut-out pressure of 70psi.  The highest the pressure gets is 64-66psi. 

Troubleshooting -
   Confirmed the check valve is holding pressure.
   Confirmed there are no leaks on the discharge side.
   Adjusted the CSV, even to the point of turning the set screw almost all the way in.

500 gl holding tank 6' H x 4' Diameter
    |
~60' 2" pvc pipe
    |
1 1/4" FLOMATIC 4202SS2 check valve
    |
Goulds HSC15, Multi-Stage Centrifugal Pump, 1-1/2 HP, 2 Stages, 1-1/4" Suction, 1" Discharge
    |
~5" 1" stainless steel pipe
    |
PK1A PSIDE-KICK Pressure Tank Kit
    10 gallon tank
        I made a support to hold the tank horizontal
        The bladder pressure is about 48psi
    50-70 pressure switch

I am at a loss.  The only thing I can think of is that the pump is unable to build pressure to 70psi.  Is there anything I am missing or should check?

If the pump is unable to build pressure to 70psi - I will then need to troubleshoot that.  I thought the Goulds HSC15 pump could go to 125psi.

Any direction is greatly appreciated.

Thanks,
Joe

Pumps, Wells, Tanks, Controls / Re: booster/jet pump application :: where to put check valve?

Got it - thank you for the advice!  I was worried that a check valve on the intake side of the pump would be restrictive and cause problems.  I thought going bigger was better.  I will use a brass or stainless spring loaded 1 1/4" check valve as suggested.

I will order a Cycle Sensor Pump Monitor for the booster pump.  I can see how that can save the pump in several situations.  I have a Littlefuse PumpSaver on the well pump.  Not sure there is a compelling reason to replace it with a Cycle Sensor.  Let me know if you think otherwise.

Thanks again,
Joe

Thank you for the response.  I found these diagrams on beecavesdrilling and friedeldrilling websites.

Can you recommend a check valve for the application?  I was looking at a 2" PVC spring(not swing) check valve.  They can be purchased at Lowe's or Home Depot.

Thanks,
Joe

Hi -
I would appreciate it if someone could review my system and provide feedback & answer questions.

I am on a well.  My well pumps water into a holding/storage tank.  That part is fine.  I am trying to finish the install of the pump and pressure tank.  The pump and pressure tank are located next to the house where the copper pipes protrude from under the slab.

Here is what I have to work with.  The pump and CSV are not installed.
500 gl holding tank 6' H x 4' Diameter
    |
~60' 2" pvc
    |
Goulds HSC15, Multi-Stage Centrifugal Pump, 1-1/2 HP, 2 Stages, 1-1/4" Suction, 1" Discharge
    |
~5" 1" or 1 1/4" steel pipe
    |
PK1A PSIDE-KICK Pressure Tank Kit - 10 gallon; 50-70 pressure switch. I made a support to hold the tank horizontal
    |
~4' 1 1/4" pvc
    |    |
    |    | 1/2" copper line for outside water faucets.
    |    | 3/4" copper line for house water.
    | check valve --- ~70' 1 1/4 pvc --- ~500' 1" pvc to shop

The top of the pump is about 9-12" inches above the bottom of the holding tank.

My question is - Where do I put the check valve for maximum flow/pressure and to reduce water hammer on pump start and stop.  What type of check valve should I get?

I was planning on putting the check valve on the discharge side of the pump.  What I can find seems to indicate that is correct.(See attached)  I was considering using a FLOMATIC 4202SS2 check valve.



Is there anything else I should consider or feedback?

Thanks,
Joe
