OR IT COULD BE A SHAFT SEAL ,CRACKED TANK LEAK IN A FITTING. IF YOU HAVE LET THE PUMP RUN OR HAVE STARVED IT FOR WATER IT IS THE SHAFT SEAL.. IF NOT THE JANDY VALVE MAY BE LEAKING. USE ELECTRICAL TAPE TO RAP SUCTION SIDE FITTINGS TO CHECK FOR AIR LEAKS. PUMP MUST HAVE WATER IN IT AT ALL TIMES !!! , NEVER USE THREAD TAPE ON A PLASTIC PUMP. IT ADDS SIZE TO FITTING AND WILL BREAK THE TANK..USE SILICONE

hold the trigger down on the spray gun and then try, the pressure is built up in the pump - the pump can't turn against the back pressure.

Working pressure


Putting 60 lbs. of pressure in the pressure tank is not the answer.

First determine that the pump is working correctly, Open the drain valve and see if you get a good flow of water. If you do then OK, the pump is working. If you are not getting a good water flow from the drain valve, then the pump is not operating correctly - maybe a bad foot valve. Next open the drain valve and watch the water pressure gauge, and note at what pressure the pump kicks on ( that's the cut-in pressure), and when it kicks off ( that's the cut-out pressure). Most pumps are set to operate at 20-40 psi, or 30-50 psi. The cut-in and cut-out pressure is set by the water pressure switch.The pressure in the water tank has to be set 2 psi BELOW the cut-in pressure of the pump. That is, if the pump has a 20-40 psi differential, then the tank has to be pre-charged to 18 psi.

To pre- charge the pressure tank , the pump has to be shut off. The Tank needs to be emptied (drained ) of water. The air pressure is then set to 2 psi BELOW the cut-in pressure. If water escapes from the air valve, the bladder in the tank is ruptured, and a new tank needs to be installed.

So, first make sure the pump is working.
I WOULD RELIEVE MOST OF THE PRESSURE IN THE PRESSURE TANK TO ABOUT 20 PSI BEFORE CHECKING THE PUMP, AND PRCEEDING WITH THE PRE-CHARGE OF THE TANK.

Return port of the intex pump is sucking in water at the top part of the nozzle


If the debris that is getting pulled in is floating, lower the inlet to about 3 to 6 inches under the surface of the water.

I had a water line bust. After fixing the leak, I lost water pressure. Someone tried to fix the problem and now we have little to no water flow. I have to pumps . The smaller pump that feeds the house is...


The nut on the larger spring in the pump pressure switch: Usually the larger nut in the pump pressure control switch adjusts the pump cut-on ("cut-in") AND pump cut-off pressures simultaneously. This is the left-hand spring (and nut) in our photo. That means that whatever the gap is between the cut-on pressure and the cut-off pressure, that gap is maintained, but the entire operating range of the pump is raised or lowered. Turning the large nut clockwise RAISES BOTH the cut-on and cut-off pressures. So turning the large nut clockwise shifts the whole operating pressure range of the pump UP to HIGHER pressures.
Conversely, turning the large nut counter-clockwise will lower the whole pump operating range. This is the simplest adjustment to make.
Photo (left) courtesy of a reader.
The nut atop the smaller spring in the pump pressure switch: this nut is used to narrow or widen the gap between the pump cut-on and pump cut-off pressures. This is the right-hand spring (and nut) in our photo).

Turning the small nut clockwise (tighter) will RAISE the CUT-OFF pressure, and vice versa, loosening or turning the nut counter-clockwise will lower the cut-off pressure. Watch out! If you loosen this nut too much you can set the cut-off pressure below the cut-on pressure and the pump will turn on and run forever (or until it burns up.)
Which nut to turn in the pump pressure switch control, and which direction to turn it, are usually visible on a label inside the pressure switch cover. Above we show photos of a common Square D water pump pressure control switch (Schneider Electric) and the label with pump control adjustment details. [Click to enlarge].
Here are Example Pump Pressure Switch Adjustment Instructions from Square -D Understanding how pump pressure control switches work and which way to turn which of the two nuts in the control can be confusing.
On a Square-D Pumptrol® 9013FSF-2 pump pressure switch, for example, Square D tells us that we
  • Turn the Range Nut #1 (the larger spring and nut) clockwise (to the right or "down") to raise [both] cut-on and cut-off pressures. This is "tightening the nut down" against the spring. ("Rightie-tightie, leftie-loosie" as Mara Gieseke says to her kids). Thanks to reader Rise for this clarification.

    In other words, adjusting the pressure on this spring shifts the whole operating range of the switch up or down, but keeps the difference between cut-in and cut-out the same, whatever it happens to be (typically it's about 20 psi from the factory.)

    If you want the pump to turn ON (cut-in) sooner
    , that is, at a higher water pressure, turn the nut clockwise or "tighter".

    If you want the water pump to turn ON (cut-in) later, that is, at a lower water pressure, turn the nut counterclockwise or "looser".

  • Turn the Differential Nut #2 (the smaller spring and nut) clockwise to raise the cut-out pressure.

    If you want the water pump to turn OFF (cut out or cut-off) at a higher water pressure, turn this nut clockwise or "tighter".

    If you want the water pump to turn OFF (cut out or cut-off) at a lower water pressure, turn this nut counter clockwise or "looser"

    Here is why the small nut is called the "Differential"

Replacing liner 18x33: forgot to unscrew pump from alum. frame while filling pool. is it safe to cut a **** in the liner to pull the plate through or would it be safer to take the foot rail and coping


I have never had to cut a hole in my pool liners when installing them. What kind of hole are you trying to cut - I am not sure what you mean by pulling the pump cover through? If you will provide further details about what you are trying to do, I can help you better.

Karcher k2400hh pressure washer, water pressure cuts out.


Hello cikanek:

Try this:

From your posting, I assume you have removed the splash cap and the nylon bypass valve cover. Connect the water supply to the pump and connect the high pressure hose and wand to the pump outlet. Wad up a small towel and place it over the bypass valve opening to catch the valve insert when it pops out. With the engine throttle closed, pull the starter cord several times to see it the valve insert will pop out. If it doesn't come out after two or three pulls, set the throttle to low and start the engine. I have performed this procedure a number of times and the valve insert always pops out. There is no real danger of the valve parts getting seriously airborn since the actual pump output volume is very low (2.5 Gal/min).

Good luck,
Ed
