Hi,
To replace the seal... the pump will need to be taken apart and the impeller removed from the shaft of the pump motor...
The impeller threads are the opposite of the pump rotation, so they are usually left hand threaded...
getting the impeller loose without damaging it is another problem...sometimes a sharp rap with a hammer and screwdriver will do the trick....other times I have held the motor shaft with a pump pliers and then used a strap wrench on the impeller....
Sometimes I have just beat the **** out of the impeller and then replaced it....

Be careful with the new seal also, as they can break or be damaged easily...a light film of oil or Vaseline will help sometimes also to keep them from leaking till they wear in...

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

Just replaced my Emerson 2hp pool motor. Turned on new motor all is working fine but water isn't filling the basket?


First of all you need to fill the pot with water. it is best to pour a bucket in or use a hose and turn the pump on and off real quick a couple times to **** some water into the pump. Once you do that fill the basket as much as possible and quickly put the lid on and turn on (make sure your lid o-ring is there and in good shape. lubricate it with pool lube so it's wet but not all gooped up). when you turn the pump on you should see water either splash, or at least start trickling into the pot. if you see water splash in, but then go dry again, or if it just trickles but doesn't prime after about 20 or 30 seconds, then you may very likely have an air leak on the suction side. Make sure your lid is sealed, the pipe goin into pump is not loose or leaking air, and make sure the pool cleaner hose is not out of the water, or the skimmer sucking air. If the pipe coming into the pump is sucking air or you suspect it might be try wrapping black electrical tape tightly all around the joint (where it threads into the pump). This is temporary troubleshooting step but works great. If there is a union or a Jandy valve where the pipe comes into the pump check o-rings and all joints for leaks.

Leaky pump on jetted tub


You might just need to tighten the bolts. If that doesn't fix it you can dismantle it and replace the O-ring. Be sure to lightly coat the new ring with silicone grease before installing it. A pool supply store should be able to help you with the right part.

My Jet Pump Looses it's prime at night.


I assume the pump is not running at night. If the pump is higher than the pool, and the inlet and outlet to the pool are both under water, then you have a small leak. This could be allowing the water to leak out of the line. Or, if the leak is higher than the pool surface it is allowing air to leak into the line, which allows the prime to run down into the pool. If you found this useful, please vote. Thanks.

My pump is making a "high pitched" whine . The pump has a sticker that states " Century pool/jetted motor, Serial # CA05F49034, Part-7-193262-28, Type-SP, FR-w484,HP- 1.5 SPL, 12 Amps


could be its has air getting in when its pumping or the motor bearings are worn out or just dryed out it could even be a partly blocked inlet filter causing this pump to whine,
try looking for inlet pipe air leaks and blocked filters
or some thing resting on the pump impeller

Our A O Smith pump/motor gets airbound everyday


Well somehow air is obviously getting into the pump line. Easiest fix is to move the pump below the water level of the tub and then gravity will keep water in there. If you do have the pump below the water level, then make sure you don't have jets shooting a bunch of air directly at the intake in the tub. If that's not the case and it is below water level, then make sure you don't have a leak in the line somewhere.
