We just bought this pump and we are getting air in the pot. We have done pretty much everything including replaced the pot gasket. I’m afraid to crank down on the union too much because I don’t want to crack it. Has more air at a lower speed but nonetheless it’s getting air. Any suggestions? IMG_6978.jpeg
 
Welcome to TFP.

Those Jacuzzi pumps are made by Hayward and it is normal for Hayward pumps to have some air in the pump basket, especially at lower pump speeds.

Unless you are constantly pulling air into the system (evidenced by being able to release air from the filter regularly during a filter cycle) air in the pot is not an issue.

And then one of these days, at a higher speed, the bubble will disappear and you will start asking the question, "Why isn't my pump having a bubble like it did before?" It will, virtually always be there at low speed and probably isn't air, but an area of low pressure.
My EcoStar, the first version of your pump, has been doing it for nearly 15 years. Its also seen in the TriStar single-speed pumps as well, no longer available. Your pump is a Hayward TriStar VS made with a Jacuzzi label for Leslie's.

Thank you another question…if I may…how do I delete a timer on this pump? Do I need to go back to factory settings and reset? Or can I run the timers all the same and timer 1 will just run as I changed timer 2 and 3 to run the same time and speed?

As for the first question we are having to release some air from the filter air bleed valve to remove air from the filter.

Union on the front should be "hand tight" plus about 1/8 to 1/4 turn. No more than that. If you can still tighten with not a lot of effort, it is too loose.
If you are able to release the air from the filter, come back 15 minutes later and release a lot more, you have a suction leak. Are there any valves before the pump? They can be a source of air (suction leak).
If all the timer are set to the same setting, nothing will change. Or set the other two to "zero" minutes, or the start and stop time to the same.

Thank you for your help. Very much appreciated

Need to ask, have you lubed the lid gasket. Tiny bubbles coming from the perimeter of the clear lid are sometimes air infiltration from the lid gasket.

Yes, and looked to make sure there was no debris on it at all. We had turn the primer down to 4 minutes so we just increased it back to 8 minutes 🤷🏼‍♀️ we are at a loss but we know it has to be coming from the suction end.

Nice picture but can you explain the suction side valve layout. What are the three valves controlling and on the return side What are the two possible positions. On the suction side the skimmers can be plugged and you can pressure test from the pump end by disconnecting the inlet /outlet on the pump and push it aside and then isolate one of the three and see what's going on. Lots of glue joints there with almost to no glue visible except right in front of the pump where it looks newish.

Yes one valve runs a waterfall (not running it as of now) one for the drain and one for the skimmer. On and off positions only water fall and bottom drain are currently turned off bc we were in the process of isolating each individual valves when I took the picture. The only glue is bc this pump was replaced because the other pump was 15 years old and was only a single speed and was on its last leg. The glue joints are for putting in the new pump.

If we run it on one timer at 2500rpm because obviously it pushes more water we only get a few tiny bubbles that we are fine with but we got this pump to be able to turn it down or up as it’s intended for to keep the water moving.
 
I have the 2.7 hp version of this pump. I also had similar issues with air in the basket. In my experience it has been the cover seal. If there is a little debris on it it will not seal perfectly. I have not used lube on mine, I just make sure the gasket and sealing surfaces are clean and the gasket is wet when tightening the cover. If it is clean it seals and does not leak air. Hasn't needed excessive effort to tighten.

I have not had any issues with the unions. They were only hand tighten a half turn or so after bottoming out (if i recall correctly).

As a precaution I also have the pump run fast a couple of times a day to purge most of the air out if any is building up.

That tiny amount of bubbles is nothing to be concerned about. You have an older filter and that tablet feeder that could easily allow air into the system each time the pump shuts down, but not leak water when it is on, that is not completely removed. Its normal for a system that age. Since the valves in front of the pump are older, I would change all the O rings, 2-stem and one lid, in all of them if it gives peace of mind. Don't worry about getting Pentair O rings, all brands use the same O ring now. DO NOT use a power screw driver to reassemble the valves.
 
With the pump off the basket will slowly fill with air? With the pump running at a low speed (less than 1000 rpm) it also slowly gets more air in it till it loses prime?

Do a pressure check on the suction side and use a soapy solution to look for bubbles on glue joints and the valves on the suction side. Maybe swapping the pump cause a glue joint to fail or a seal is failing on one of the valves.

Silly question, is you water level low or the skimmer door stuck?
