    Suggest having a check valve installed to the front of pump the intake , then backwash pool hooking a stong wet dry shop vac to the outlet where waste water come out ,this will assist pump .Important to make sure that a return lines and skimmer lines completly open . Make sure pump lid is tigh ,and the collar clamp between filter tank and the multiport is also good and tight .This will fix your problem now and in the future . You can also follow the same method to prime pump without the check valve ,but this will continue to be a problem and a procedure you will repeat without check valve .Backwash is my recommendation so the sand soak s good during the filling with vacuum assist . This sand filter with cakedupped materials .

Check to make sure that there is enough water in the pool and that the weir door in the skimmer box isn't jammed in the upright position

SOURCE: my intex pool pump is surging and won't stay primed???

i think its pump side first as its easier to push water through a filter rarther than trying to **** it , Also the only reason it could loose its prime is through air getting in the system.

SOURCE: lost prime

Turn off the pump at the timer and remove the lid to your pump where you empty the debris from the basket. Get a hose or bucket and fill that resevoir with water and get the lid back on as quickly as possible. Turn on the pump and it should start to prime. On the filter, there is a air relief valve. Depending on the filter, it will pinch and twist, or there is a knob to uncrew. Doing that as the motor is running allows tbhe air that has built up inside to puge out. Once a steady stream comes out close the relief valve. May need to tryh it more than once.

SOURCE: Hayward Self-Priming Pump with AO Smith 1 HP 56J

the pump must not have any air leaks in the suction side of it,, or it will just **** air and not water,,, water is very heavy you see, however i think its the impeller in the pump thats the problem,,,you should try to put water in the out let of the pump so you fill the pump with water first if its dryed out it may just wear out the impeller before it starts to **** water up, if this still dont work turn off the stop **** and strip out the pump to look at the impeller any wear on it and it will need a new one fitted
i hope this has help you, good luck

I have a Hayward sp3400vsp. The pump runs all night some times, the screen say is priming, it will shot off manually, and it wont do it all the time. help??

Sounds like the pump is sensing that there is a problem with water flow on the suction side.

Could be caused by air being sucked into the system. Do you notice air in the strainer chamber? Or bubbles coming from the inlets in the pool?

Could also be caused by something clogging or restricting the suction line.

Pool pump wont prime when in pool mode, but will run in hot tub mode. Hot tub is 3 ft higher than the pool... is this a bad impeller? I think it may have run for a few hours without a prime , as I...

I assume that it pumps from/to the hot tub. If so, the pump is fine. Look for any air leaks in the piping/hoses from the connection in the pool to the inlet of the pump.

I have a brand new hayward e series and it will not hold prime

When you say it won't hold prime I assume you mean when you turn it off either manually or on a time clock? If this is the case you must have an air leak somewhere in your piping system or in your pump. Could the pump seal be leaking. Gasket on pump strainer ("O" ring) Is the strainer basked crecked. I've found several pump strainer assemblies with small cracks that won't even prime at all if there is much lift. Check for cracks on all threaded fittings, IF the fittings were overtightned then it can crack the fitting, like in pump inlet and outlet. Listen for a hissing, sucking sound when you turn the pump off.

We do not know where the air filter valves are

Air filter?

Remove the strainer basket cover ... fill with water ... check the gasket ... replace if questionable ... close the cover and SNUG the top down. Start the pump ... it should run just fine.

If you are sucking air, tighten the strainer basket cover a little.

Still sucking air? You will have to find the air leak. You might plug the leak with plumbers putty.
