Seeing bubbles in pool when filter is running

The water level is high, im not sure if this is expected or normal? I’ve attached two videos of the pool side and the actual filter pump
Pool side:
Pump:
Not normal, is the water level in the pool high enough that the skimmers are running dry? Are the skimmer weir doors stuck closed?
 
Looks like you have a suction side air leak...


Do you use Pool Lube - Further Reading on the pump lid O ring? If no, try lubing it up.

First thing to check is always the pump-lid O ring. It needs to be lubed. Would like to see more of the plumbing in front of the pump.
Hey @1poolman1 i bought a new o ring and also replaced the basket inside the pump and also replaced the skimmer. I filled the pump basket with water, closed it and turned on the pump, allowing it to prime, water reached the top , but then slowly started decreasing inside the pump, and the level just kept going down. Ill send a video of it tomorrow

Have you checked that the skimmers have water in them when the pump is running?
 
@1poolman1 @Bperry , here is a video of the entire process im doing, i tried to show as much as i could and angles of the setup.
You did not tighten the pump lid very much. It’s a two handed operation and will let air in if it’s not tight enough. But also you will get air bubbles like that when the pump restarts after being off. It just take some time for the air to get purged.

But also go over to your skimmers and make sure there’s water inside of it when the pump is running. There’s a weir door (flapper) that can get stuck closed and prevent water from getting into the skimmer which will then make the pump suck air.

Any of the plumbing in front of the pump can be the source of that air. Have you checked the 2 O rings on the union at the pump inlet? One at the actual inlet port, one under the union nut? Is the union tight? Is the union tight into the pump?
The valve before the pump may also need new O rings, two on the stem and one at the lid. Doesn't matter which brand of valve that is, all the O rings for those type valves are the same.

Hey @1poolman1 i havent checked those pipes or o-rings, since i bought the house 2 years ago. One question as im about to inspect, do those pieces come off? Like i thought the unions would be glued on, how can i inspect the orings on those pipe pieces?
 
What is the skimmer weir door, i dont think i have one
Open the top of the skimmer lid and there’s a big flappy door that lets water in or can restrict it if it’s stuck closed. Just check that there’s enough water actually getting into the skimmer when the pump is actually running. I had a similar problem and that was the cause.
