Air in system,turn the pump on air bubbles come out of pool water jets,not good suction

If your Sta-rite vertical mse-7 pump will not prime, there are a few things you can try to troubleshoot the issue:

1. Check the water level: Make sure the water level in the pool or spa is high enough to reach the skimmer and the pump. Low water levels can cause the pump to lose prime.
2. Check the skimmer basket: Make sure the skimmer basket is clean and free of debris. A clogged skimmer basket can restrict water flow and prevent the pump from priming.
3. Check the pump lid O-ring: Make sure the pump lid O-ring is in good condition and properly seated. A damaged or misaligned O-ring can cause air leaks and prevent the pump from priming.
4. Check the suction plumbing: Check the suction plumbing for leaks, cracks, or other damage. Any air leaks on the suction side of the pump can cause loss of prime.
5. Check the impeller: If the impeller is damaged or clogged with debris, it can prevent the pump from priming. Remove the pump basket and inspect the impeller for damage or debris. Clean or replace the impeller as needed.
6. Check the pump seal: If the pump seal is damaged, it can allow air to enter the pump and prevent priming. Inspect the pump seal for damage and replace it if necessary.

If none of these troubleshooting steps resolve the issue, you may need to call a professional pool service technician to diagnose and repair the problem.

Found a few resolutions, hopefully one of these work

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.

Check your pump pressure on the suction side. If there is any air gap in your pump strainer pot (if you have a see thru see thru strainer cover) then you have a leak on the suction side. Auto matic cleaners need ample pressure for them to move. or you might need to backwaste the filter check your pressure gauge. If none of these help its more then likely the gears in the cleaner. also check your cleaners hoses

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.

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.
Time to Open the Swimming Pool

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.

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).

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.

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.

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
