    modle # Fp4222-08 The pump won't shut off. replaced presure shitch, put a shutoff valve at discharge side. checked tube to presure switch,it is clear. loosens screw on top of pump that controls preasure. still won't shut off.

  • jdomino May 06, 2010

    the pump is pumping water. 40lbs preasure. just shy of hitting 60 to turn off. i can turn off power that dose work, but won't hit 60lbs

  • jdomino May 06, 2010

    So what your telling me is i need to find another expert?

  • jdomino May 06, 2010

    I only use this pump for my garden and other out door chores. I have a two gallon tank on top. I havn't checked the presure of it yet. I'm thinking it's supposed to be 18lb.

  • jdomino May 06, 2010

    After reading my other imputs,the tank i have is a bladder tank.

  • jdomino May 06, 2010

    the pump is a Flotec mdl# FP4222 08 3/4hp. I use it to water my garden

  • jdomino May 06, 2010

    I saw the unplug it. That is what i've been doing since this problen started. On a 3/4 acre garden that is alot of walking, when i didn't have to before.

  • jdomino May 06, 2010

    also it is a new gauge. I have a pond right next to my well. The pond is 8' deep,my well is 35' deep and has a strainer 4' long on it.

  • jdomino May 06, 2010

    this is the reason i changed everything. No i havn't let the air out of the tank. Also didn't check air preasure

  • jdomino May 06, 2010

    By the way your ?s are right.

  • jdomino May 06, 2010

    my presure switch is on at 40 off at 60 . when the water is turned off it just won't reach 60. it did before this problem started.

  • jdomino May 07, 2010

    I checked the air presure and it was hardly any air in it.I put 22lbs air in it and it works thanks.

    do you have an adjustable pressure switch?

    Why are you looking for 60psi?

    Most household water runs at 35-40psi.



    So - let me see if i have this clear - based on your other comments....



    You have a well.

    Your main pump (into the holding tank) is a FloTec Fp4222-08.

    This pump fills the holding tank - but does not shut off when up to pressure? Or never reaches the pressure switch's setpoint?



    Have you bled the air out of the tank?

    Air compresses - water does not.



    Was the reason you changed the pressure switch the same one you are having now?

    Or has it happened with the new installation?



    Thanks!!



  • blueextc3221

    Then your tank is leaking pressure.



    If it is a bladder tank CLICK HERE



    There may be a pinhole in the bladder - not allowing the pressure to build - especially since you have changed the pressure switch with no resolve.



    Eventually the bladder can leak just from use too. After all, it flexes every time the water is used, so wear and tear is expected. Once the bladder leaks, the tank reverts to a plain style of pressure tank (with a ripped rubber bag inside), so the compressed air slowly bleeds out. Plus you can get chunks of rubber in your water lines, which has its own set of problems.



    You can re-charge the air side using an air compressor.



    Find the schraeder valve on the top side of the tank. SEE IT HERE It is used to charge the air side of the bladder ( and also may be bad ) Once charged - spray a liquid soap/water solution on it and see if it is holding the air inside.



    This is the most common problem. The tank should never need recharging unless the valve leaks.



    Thanks!

  • blueextc3221
    blueextc3221 May 07, 2010

    THe air side of the bladder should be charged to approximately 2psi under the low pressure switch setting of 40psi.



    Check the air pressure - im sure your problem is there.

  • blueextc3221
    blueextc3221 May 07, 2010

    Glad you found the culprit - but remember - the only way for air to dissipate from the charge side is to have a leaking schraeder valve - or leaking bladder.



    You should have 38-40PSI air charge.



    Thanks for using FixYa!!

Depending on what tank you have, you can't be pumping any water, just air. Either the impeller is shot, the gasket is gone, or the well is dry. Or it has lost it's prime. If you have an old tank with no bladder, does it have a glass housing on it for pressure? Did the pump run on,off, on,off, ? Can you see a water level in the tank? By condensation on the outside? You can try shutting off the power, drain the tank, and try filling it back up. And check the air pressure at the top of the tank. But I don't think it will do any good if it has been ok till now. I would say the impeller. Hope this helps.

    I have replaced about everything I could think of to get a pump going once,and ended up with nothing, just kept running and not pumping. I tried a new impeller, air pump, diaphragms, gaskets, foot, everything, had to call the pump guy and he came out and told me I had the wrong impeller, the diaphragm was no good, and the gasket was shot, all new, He replaced everything and it ran fine. Cost me $75. It took me all day going crazy trying to figure it out. But I learned a lot that day. So you might be pumping water, but no pressure, there is a leak somewhere in the air pump or the impeller, Don't forget, your pump not only lifts water up, but it pumps air down. So somewhere you have an air leak. You will have to pull the motor off and check these parts out. The little spring loaded thing in there has to be a good fit. Hope this helps.

    Ned White May 06, 2010

    No, I wasn't saying you need another expert, I am just offering help from past experience. You can change parts all day and still not hit it. But a pump guy will do it for you and save you a ton of trouble. I was thinking impeller, but, if you only use it for garden, you really don't need 60 lbs. Did you try turning up the high pressure adj just to see if it would pump more? My tank used to get water logged, too much water with no air, you had to drain the tank and fill it back up. I finally got one of those float ball things on there and haven't had a problem since. You can keep the thing going here no problem and see if someone else can help you.

  • Ned  White
    Ned White May 06, 2010

    Here is something for you to try. Get a new pressure gauge, you might not be getting a true reading. The specs for the new pressure switch are inside the cover. It may only pump 38 lbs. Meyers pumps, ( I know yours is not) are famous for under pumping. Has the motor ever been replaced that you know of? And one more thing, the water table, is it low in your area? Try hitting the top of the pipe with a big hammer, it might have sucked up a rock. Without seeing this thing, it is hard to tell what is happening. And the last thing you can do is adjust the pressure down to the 40 lb mark. try it.

Hello. I have been working with pumps for almost 40 years. Since you changed the pressure switch, I now want ou to check the line as it may be stopped up with minerals. Also, on some pumps there is a item called a head pressure control valve(plug looking item with a threaded screw in the center of it)....if you have this screwed down the pump will build lots of pressure but will not put any water into your tank.

;turn coleman hottub on - flashes "pr" for a few min. then it shuts off


Hi,
If your Coleman has Balboa electronics 'PR' is to notify you that it is in priming mode.
It could also be your pressure switch. On most tubs the pressure is mounted on the heater. If this switch is not reading correctly it could shut the spa down to prevent heater overheating.

My MAC 700 laboured to kick in to build pressure, and then finally quit. It won't turn on with the switch in the


All compressors dump a little air when they shut off, it's the air in the pump head and discharge tube. This bleed off should only last two to three seconds. If this pressure isn't bled off the motor won't be able to restart when the pressure drops in the tank becuase there will be too much pressure in the pump head for it to start turning again. If you have a longer bleed off or if the motor is struggling to restart most likely you have a stuck or broke check valve. It's the piece where the discharge tube connects to the tank. It's designed to let air into the tank but not back out so the pressure valve can bleed off the air in the pump. On rare occasions you can remove it and clean it out but usually they have to be replaced. You would need Makita Part Number 409004-E.

Thank you for posting your question here on Fixya.com.


The orientation for a sump pump/check valve are the pump is in the bottom of the pit, the discharge pipe leads up into a check valve, usually very close to if not threaded into the pump discharge, and then the pipe continues up and out to wherever your water discharges to. The weep hole needs to be below the check valve.

The hole is there to prevent an air lock in the pump which would prevent it from moving water.

If the water trapped in the vertical run of the discharge pipe is returning to the pit once the pump shuts off the problem is the check valve is not holding or the hole is on the wrong side of the flapper assembly. Did the check valve come with the unit? If not, you will need to fix it if you can or replace it.

To drain the pool, you have to change the position of your "backwash" valve.
Shut off the pump.
See if there is a DRAIN position on the backwash valve.
You could probably use the BACKWASH position, too, only water will go through the filter and then out the normal backwash pipe.
Turn the pump on briefly to see which pipe water comes out. Shut the pump.
Put discharge hose on that pipe.
Turn pump on until pool is low enough.
Return backwash valve to filter position.

if it is lifting both valves I would say that the pressure switch (regulator as you call it) is defective, if you try to shut it off using the manual switch and it keeps running, I would say that the switch is welded shut. if it does not shut off by 125 psi then it is faulty. The pressure switch is what controls the motor in response to pressure in the tank.

Pump is set to turn off at 40psi. Has been working fine all summer, but now, after 3 weeks away I returned to the house to find the pump running.It won't presurize beyond 20psi and doesn't turn off.


Your pump is hooked to a pressure tank? Shut off the
pump, and drain and empty the pressure tank. Then,
put the power on, and load the pressure tank to 40 psi.
This should shut off. If it doesn't, You must replace the
Air Volume valve at the pressure tank, in order to maintain the right air volume level of the pressure tank.

Pump is making grainding noise like bearing is running dry model num 816549-091


Before it gets damage, you must replace the worn out bearings. Shut the power supplying the pump off. Close all the valves (intake and discharge). Take the pump off from where it is installed and disassemble it to change the bearings, as well as the mechanical seal. Reassemble and reinstall to its location. Open the intake valve if there's any. Open and fill full with water the priming port, and have it closed thereafter.
Put the power and switch it on to run the pump. Then,
slowly open the discharge valve to desired level. Send
us your e-mail comments for us give further assistance if needed. God bless you.

I cant find the fuel shut off switch on my 2008 gsxr 600 I dont have the owners manual either


THe fuel shut off valve is also called the "petcock" it should be located on the side of the gas tank on the very bottom. I think it is on the right hand side. Look for the fuel line that goes to the fuel system and you should be able to trace it to the shut off valve. It should have 3 positions, ON / OFF / RESERVE
