Try the shaft seal?

Otherwise, you have a suction air leak somewhere on the suction side of the pump. That means somewhere between the front of the pump all the way back to the pool.
The easiest to check, least expensive and the most common, will be broken thread sealant on any 'threaded' fitting, bad O-rings or seals in valves and unions, or you have a crack in your plumbing. And... It may be underground. Good Luck

SOURCE: pool pump won't prime

check for air leaks, cover o-ring is common culprit. anything in front of pump can cause this.

SOURCE: Pool pump will not fill back up

It sounds like you are sucking air into the pump. Make sure strainer baskets and pump baskets are clear, and the valves are in the right position. Also check the water level in the pool, and make sure that the pump is not sucking the skimmer dry. Next try lubricating the gasket on the pump lid, or if it is in bad shape (flattened/cracking) replace it. If this does not solve the problem put silicone around the inlet to the pump (silicone is a temporary fix that could last days or months--for best results replumb with teflon tape and sealant). If all that fails you could have debris stuck in the impeller.

SOURCE: suction with my pump

First thing to check is the removal of any winterizing plugs in the return lines. Sometimes plugs are fitted inside the lines in the pool making them not obvious. Secondly, check that any valves in return line are open. Many never lube type valve handles are oppositely positioned as compared to ball valves. If the multiport valve hasn't been tampered with, then there really is no other place to look. The flows everywhere but back to pool.

SOURCE: I cannot get the pump to pump water, motor still works.

Sounds like air has gotten into the pump and froze the pump. It will need to be replaced due to that reason. You can get a repair kit for the pump but it will not be gaurenteed to work

SOURCE: air in filter on hayward above ground pool.

This is common the first 30-60 seconds after turning the filter on. The filter is purging its self of the air, sometimes algae or small debris will shoot back into the pool as well.

If it is constantly getting air then replace your o-ring on the that clear cover (Strainer Cover) make sure you use a lubricant, and like djtc66 said re-wrap all threaded areas with teflon tape.

It looks that my filter has some air in it, how can I take it out?

In a properly plumbed pump/filter system, while the pump is running air can be introduced only through the suction side of the hydraulic system. (Water can cavitate within the pump, but this is not air, rather water vapor in bubbles. Once the pressure is reduced downstream of the pump turbine, cavitation will cease and the bubbles will return to liquid water. Nevertheless, pump cavitation is a serious problem that also needs to be avoided.) In other words, air gets in upstream of the pump. Downstream the water pressure would be to great to allow ambient air to enter the system -- rather water would leak out.

On the upstream side of the pump there are several places to look for air suction:

1. Most common, water level too low in pool, and air enters through skimmers. Most pool owners discover this on their own and correct the problem.
2. Less common, suction-side fitting or seal is not properly sealed. This could be at the pump basket housing seal, the pump drain seals, an upsteam valve, etc. If you have antifreeze ports, look closely at these fittings. Be sure to replace seals often. Teflon tape should be replaced every season. In many cases the only way to find a bad suction seal is by seeing air in the pump basket. In a properly sealed system you should not see any air in the pump basket after just a few minutes of starting the pump. If you see a pocket of air continue in the basket after a few minutes, you likely have an air source upstream of the pump. The effects of a leaking seal will be amplified if the skimmer line is blocked with debris either at the skimmer or in the lines. The pump continues to work hard to suck water into the system. If it can't get water, a leaking seal will be the source of vacuum release via the entrance of air through the bad seal.
3. Less common yet, a broken skimmer line from the skimmers to the pump, potentially underground. Obviously, this is in the most costly to repair.

Here's an example of what one might find. A pool owner has forgotten to replace the Teflon tape on his antifreeze ports for many years. Since these ports are opened and closed both at the beginning and end of each season, the tape has worn out and is no longer sealing the ports. He sees a large bubble of air collecting in the pump basket, and a stream of air bubbles in the return water stream going back into the pool. His fix? Remove the antifreeze port plugs, remove the old Teflon tape, replace with new Teflon tape, then replace the plugs.

Air in whisperflo window, bubbles from pool jets

This is a air leak on your suction side between the skimmer and the pump. You will not see water in the yard on the suction side usually, only the return. It is usually just the fittings around your pump or the seal around the pump lid, check those first and make sure you do not have a loose clamp or a damaged or dry seal. If that is not it then call in your local service guy to determine where the leak is. They will most likely pressurize your suction line to find the leak. Hope that helps.

Hayward Power Flo LX Is there supposed to be water in the strainer basket during operation

Yes, absolutely, no air at all! You should not see bubbles in the pot. If you do, then there is an air suction leak.

Note: many people they have a problem when they actually don't. When the pump is operating efficiently & properly, "Solid" water in the pot/basket area, it will look like the pump has NO water. But if you see Pressure showing on the pressure gauge or water being moved through the inlet jet fitting, then you know the pump is working, you have no problem.

If you actually do not have water in the pot, then you need to prime the pump.

Pump is running but not returning water to pool

If you have suction, you must have discharge. It is a law. Your water is going somewhere. Check for your water going to waste. Are you CERTAIN you have suction ? When I first read your question, I suspected a impeller with a spun out center. The motor runs but there is no pressure and no flow.

Let me know ...

Hello, I have a pentair whisperflo 1hp pump and it seem to have very little water pressure coming into the basket and my skimmer has very little suction as well. Any suggestions Thank you, Ali

turn the pump off, remove the lid and pump basket. reach your finger inside to see if there is any debris caught in the impeller. MAKE SURE the pump cannot come on at any point while you're working on it.
That should do the trick, if not, investigate an air leak on the suction side of the pump. Causes: bad lid 0-ring, threads on suction fitting leaking air in, or if there is a union on the suction side, make sure it's tight and the o-ring is in good condition (add lube as necessary).

When the pool pump is working water flows freely with good pressure but there are air bubbles. when the barracuda is connected the pump looses the pressure, the g3 moves sporadically and the water flow is...

If you are seeing air bubbles in the leaf pot on the pump, you have an air leak on the suction side somewhere between the pump and the pool. Check the pump lid o-ring for any dirt, leaves, etc. Make sure the O-ring on the lid is not cracked, dry (lubrication like Aladdin's Magic Lube) or compressed or flattened. Also check your union or threaded connections to the pump suction (end) to insure they are tight and sealed. If this is an in-ground pool, and equipped with valves to control skimmers and bottom suction, close each valve separately to see if the air bubbles diminish. If the bubbles diminish when the valve is closed, then the air leak is in the closed section from that valve back to the pump. If the air leak increases, the air leak is in the still open line. Since the Kreepy crawly works on suction and increases the vacuum, the air leak will become more apparent, resulting in a loss of pump efficiency and flow, resulting in lost performance on the cleaner. If so equipped, close off the bottom drain valve and increase the suction on the vac line. I can provide further details as needed, but will need more information from you regarding actual equipment layout.

My Hayward sand filter is blowing air and debris back into pool. When I shut it off, air/water comes billowing up through skimmer. What could be causing this and how can I fix it?

You have an air leak in your system somewhere. When it get's in your filter tank the water pressure compresses the bubble and when the system goes off the bubble expands and rushes back through the system and blows the skimmer lid.
Check your pump lid and "O" ring for cracks and be sure it's lubed correctly. Check the plumbing going into the pump and be sure it is tight. If you loose prime or the pump runs with a dirty basket for any leingth of time the water will overheat and shrink the plumbing to loosten it. If this is the case you will need to replumb the pumb.
These are the usual things, but it could be many others. If you open the filter it should have an internal air bleed. Check to be sure this is in good condition and sticks up into the top of the filter.
Good luck, I hope this helps.

Water surging back to pool when shut off

sounds like you have air built up inside the filter when the pump shuts off. the most likely cause is a suction side air leak, bad lid o-ring or union o-ring or maybe even the threaded fitting going into the pump. When you turn the pump off, you may be able to see water squirting out wherever the leak is. Once you find/fix the suction side leak the filter should stay filled with water and not surge backwards when the pump turns off. Make sure you keep the filter clean as well.

Hayward Self-Priming Pump with AO Smith 1 HP 56J frame motor. Stopped moving inground pool water. Added water to pump basket (low). Turned on pump, return jets sent "bubbles" into pool, stopped, then...

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

In-g pool loss of pressure and bubbles from return line any ideas

If you notice bubbles in the water returning into the pool from the eyeball/discharge, or water in the strainer basket is visibly swirling (bubbles visible) odds are you need you replace the o-ring on the lid of the strainer basket in the front of the pump. This basket may also be clogged with debris, which also effect pressure. Could also be a cracked or warped strainer lid. Should be easy to see when you remove to check o-ring. Once you remove the strainer o-ring make sure you lube it with a good silcone based lube.
