Add water to the pump pod basket and you might have to do this several times but it should prime.

How do i prime this swimming pool pump?


The normal procedure would be to unscrew the top of the inlet basket and fill that with water until it flow out down the inlet pipe, then replace the top cover. Make sure the skimmer box basket is clean, the pool water level is high, or put a fast running hose in the skimmer box to make sure the primed pump does not have to pull the water up from too low at the inlet.

If it will not pull the pool water in when started, then -
- there is a leak or blockage somewhere on the inlet side
- the pump impeller is damaged
- the filter is clogged too much and causing back pressure
- the pump power and pipe sizing are mismatched

I have an air leak in intake line


Question:

What do I do if my pool/spa pump is loosing suction or prime?

Answer: by Osko Pool n Spa Pool Pump Losing Suction or Prime If your Swimming Pools Filter system looses Prime, it is caused by one of the following conditions.
Note: The lost of suction/prime is caused a leak which in turn sucks air into the system. The lost of suction/prime will be anywhere from the Main Pool Skimmer(s) to the Pool Pump. It will NOT be from the Pool Pump to the Pools Main Return(s).
1) First make sure that your water level is high enough so that the skimmer is not sucking air.
2) Check the Pump Pot Housing Lid Seal and be certain that its completely sealing and is not
Sucking air into the system. Check the lid for cracks. If either condition is true, replace the Pump Pot Lid Seal and/or entire lid
3) Check all fittings, clamps and hoses from the pools skimmer to the Pools Pump Pot Housing for wear, tightness and leaks.
4) Check Pool Pump Pot Housing for cracks.
If everything aforementioned in good working order, the next thing to check is the Pump Pot Housing Main Seal and the Pumps Impeller and finally the pump.

5) While the Pool Pump Motor is running, carefully inspect the area where the Pump Pot Housing attaches to the Pump Motor. See if there is any water leaking. Next, spray the area with water and see if the water is sucked into the Housing. If so, your Main Seal is damaged.
6) Disassemble the front half of the Pump Pot Housing from the back half and inspect the Pump Motor Impeller. (This is a high suspect part). See if there is any sign of wear or breakage. (This happens over time from debris in the water passing over the impeller). If so, your Impeller is damaged.
7) Re-inspect the Pump Pot Housing Main Seal by standing the partially disassembled upright, with the Pump Motor towards the ground. Pour water over the impeller and into the cavity. See if the water leaks thru to the outside of the Pump Pot Housing. If so, your Main Seal is damaged.
8) Remove the cover from the rear of the Pump Motor. Using a large standard blade, (straight), screwdriver or wrench... turn the main motor shaft. Listen for grinding and/or rumbling and feel for any restrictions while turning. If you hear or feel either, your bearings and/or brushes are damaged.
If everything seems to be in good working order, then you need a new pump... not just replacement parts

Is there enough water in the pool 1/2 way up the skimmer flap to prime the lines, Are the skimmers clogged? Are all valves in their correct position? Have you checked the gasket on the top of the filter? Is the spring weak/broken, handle should have some tension, has the gasket rolled, torn or slid?

My pump is not drawing water from the pool, dissambeled pump and it is clean and free of obstructions. removed pump from motor and inpeller is spinning when plugged in and the defuser seems to be ok...


Ok I''m assuming the pump is mounted higher than the water level in the pool. This means it needs to be primed. If everything is air tight, it should be self priming. Check to be sure your piping is open from the skimmer to the pump and not clogged. You can put a garden hose into the suction line of the pump and feel for flow coming up out of the bottom of the skimmer. If that is ok, then fill the pump strainer basket with water. Be sure filter is selected to filter. Make sure that the basket cover is tight to the cover gasket. After filling basket with water, quickly close the cover and start pump. If it still doesn't work, fill the basket again with water and check for any leaks. If the mechanical seal is leaking, it will not self prime. I'm not sure what type of pump you have, but Hayward has complete manuals for their pumps on www.haywardnet.com. Most pumps work about the same. GOOD LUCK!

You have air infiltrating the vacuum line somewhere. The hose may have a swivel cuff on one end that must be in the water, not attached to the skimmer. Next, check the gasket on to p of the pump housing. Under vacuum, the gasket may bleed air into the system shutting down the pump flow. Lastly, check the skimmer thoroughly for small cracks. Again, under vacuum it may open and allow air to infiltrate. The only way for a filter to go from 10-0 pressure is if the pump loses prime ie: air infiltration. Hope that helps.. Rob

My pool pump won't prime


If the pump is above the pool water level the it is unlikly that the tank will fill completely with valves open (which is ok).Most pumps are self priming and will pick up a prime with water level below suction inlet on strainer. Try starting on main drain again and slowly open skimmer line. Did you remove water from skimmer line and winterize(if in cold weather climate)during closing?.I know this sounds stupid, but make sure water level in pool is well into skimmer. If air situation remains after scspriggs' and these thoughts then prepare for a pressure test on skimmer line to determine location of leakage.
