There doesn't seem to be enough pressure. If it is connected with the sprinklers, you might have to separate the two. You can try to increase the pressure but be sure not to break the sprinkler system.

SOURCE: Sprinkler system, pump makes humming nose but never turns on

Is this a MQ3-35??? If so, it is most likely the capacitor. This is easy to replace. Take out the 4 screws from the push button cover. The capacitor is the white plastic cylinder with wires plugged in the top. Put the wires in the new capacitor exactly the same as the old one. Be sure to unplug that pump before you do anything.

SOURCE: Flotec Sprinkler Pump not priming

it might be that the pump is prewired at 230 volt and you are running a 115 power supply to it, if motor just humms and little water comes out this might be your fix

SOURCE: Sprinkler system problem.

the bleeders or solenoids are probably open or loose on all the zone valves.close each of the bleeders and the water in each zone will stop.The zone valves are usually installed ad part of a manifold enclosed in a green box installed flush to the grade or grass. Pull the cover off to expose the zone valves

SOURCE: We have an above ground

Sounds like this is an issue of gravity allowing the lower level fountains to take all the water from the central (higher) fountain.

The pump needs to either be much stronger OR you will need to restrict the flow out of the lower fountains until the upper fountain starts to work OR reduce the number of lower fountains (this is just another way of restricting the flow out of the lower fountains).

I don't have details of your pump and fountain models but you won't get water up to the higher fountain if it can flow out of the lower fountains faster than you can pump it.

Good luck.

    Not enough flow and pressure to run sprinkler system

    pressure in centrifugal pumps depends on the number of impellers in the pump housing, the clearance of the impellers to the housing and the power of the motor to drive the impeller/s
    volume flow is also important as a pump without a high output will not produce pressure
    check the jet size at the foot valve that is used to help lift water to the pump
    It is a jet pump and will have a smaller line back to the foot valve for that purpose
    next wil jet pumps if there is too much flow to the outlet , the pressure required to help lift the water to the pump is reduced and the volume is also reduced
    you indicate 4 sprinkler heads per zone but how many zones are operating at one time
    check the expected delivered volume for the new pump against delivered volume of the old pump as a starter to find the reason for the poor performance of the new pump
    check also the rpms of each pump as that also has a bearing on volume produced

    I have an aquamate pump and when i connect it to a continuous sprinkler it stops and starts contiuously

    The pump is putting out too much water for the sprinkler.
    You can raise the pump shut off pressure at the switch until it is higher than the pressure that the pump runs at with the sprinkler operating. You should have a surge tank connected to the system to give the pump time to balance with the sprinkler.
    You can use more water with the sprinkler. This could mean adding another sprinkler or increasing the nozzle size of the existing sprinkler.

    I have 1 and 1/2 horsepower sprinkler pump that wont prime. As soon as the end piece fills, it will empty if I open the end to the sprinkler.

    I don't know what is your system set up. However, the system set up should be the following;
    1. Your 1-1/2HP sprinkler pump must be installed at
    a fix location nearest the water source. (Complete
    with power and plumbing lines.)
    2. At the end of the suction line is a vertical check
    valve with strainer.
    3. The suction pipeline must be connected to the
    suction port of the pump.
    4. At the discharge port, a flow control valve tee must
    be installed. The flow control valve tee top is
    covered with a plug, which serves as the priming
    port when opened.
    5. After the flow control valve, connect a short nipple
    so that you can put a gate valve to stop the water
    flow or allow the water to flow. You may connect
    a pressure tank at this point or you may connect
    the pressure hose going to the sprinkler.
    6. To prime the pump, open the plug at the flow
    control top. Fill it full with water, replace the
    priming port plug.
    7. Turn the flow control valve to full closed position.
    8. From full close position, switch the power on.
    9. The pump now run on and off due the pressure
    switch setting. Slowly open the flow control valve
    such that the water pressure remains steady.
    10. Take note of the pressure.
    11. Shut the power off, and connect the sprinkler
    pump hose.
    12. Put the power back on, and allow the pump to
    run with the sprinkler.

    Under this set up, you can run the sprinklers when your pump is running. Hope this will solve problem.
