What spa jets are these?

RIGHT! I just have a pipe that sticks up in the little garden area next to the spa.. it acts like a snorkel sucking in air for the air side of the Venturi. But even after I fixed all my Venturi nozzles and the eyeballs, I still get stronger flow/bubbles from the get that is closest to the pump, I just think it's the nature of the beast.

So the mystery continue. Filled the spa and flushed the lines last night. I have 5 jets in total without the nozzles in, the strongest one is the one closest to the pump, and the rest were somewhat less. The shorty nozzle was plugged in to the jet closest to the pump, and the rest in the other 4 jets. One of the nozzles broke on the take out. Next up is to reinstall the nozzles back in the same locations and see what happens. BTW I used to have a blower that I never used as 1) is was too loud and 2) it bubbled so much that it shot water out of the spa. So I cut it out 2 years ago and capped the pipe. Considering reinstalling a new, much quieter one, back with the pool equipment. Also, I called waterway and sent them pics and they said these are not from them.

If you have air coming out of the jets combined with the water, you don't need a blower.

Do you have any pictures of the spa plumbing when it was being built or did you buy the house with the spa?

It looks like the threads are different for the short jet vs the others.

If you can find the jets, I would size them all to the smaller jet (5/16")

Might try sending the pictures to InyoPool to see if they have any ideas.

Try uncapping the pipe the blower used to set on. That should be your air intake. You might find you do not need a blower. My system has plenty of bubbles without a blower.

Spot on @mknauss . Sure enough the blow out worked both on the water lines and did the air lines. Plenty of bubbles and even pressure across them all, so no blower needed.

Only 'issue' now is the one broken jet nozzle doesn't provide any back pressure so no bubbles. I barely put my finger on it and bubbles galore. Would like to try an find a replacement so will check with inyopools.

Also thought about 3D printing one which would likely work, just not sure of the material would hold up to chlorinated water. Anyone have experience 3D printing a submerged piece?

Try putting the busted one in a different jet, and see if the low pressure follows it.

Cut off the broken jet so it looks like the others. It shouldn't really need to be that long for the venturis to work. However, it does need to squared off.

The thread is probably a standard pipe thread. So, you probably don't need the exact same nozzle. Find out the thread and get a different nozzle with the same thread. Just bring it to the hardware store and see what the thread is.
