One way to control that is to add a 3 way bypass to the standpipe to bleed some of the air out.
I’ll take a look. If we can ever get a day without rain soon, I’m going to get my pb over here to take a look. It’s only a couple of weeks oldThat should not be a requirement. I can run mine like a pressure washer and if the blower is off will draw air on its own. Is there a check valve installed on the standpipe? If there is pull the blower off and see if it sucks air with the jets on. Is seems like the air line isn't installed correctly but maybe the blower is just defective.
I’ve been reading more about people having issues with their spas not bubbling. I didn’t realize I should be getting bubbles in the spa even without the blower on. I’m getting no bubbles at all with or without the blower. If I understand correctly, I should be getting bubbles without the blower but the blower just increases the intensity?
Some people have had luck by increasing the diameter of the return jet eyeball opening because the smaller opening was creating back pressure. Thoughts?
Ok that makes sense. I’ll try removing the return jet eyeballs and see if anything happens to rule out the back pressure theory. Hopefully I’ll get my Pb over here soon to figure it out himself!!It all depends on how the spa air line is setup.
If the blower is sitting on the spa air line you may only get bubbles when the blower is operating. The blower is causing too much of a restriction to pull air in without the blower.
If you remove the blower from on the air line it is more likely you will get some bubbles. That depends what type of venture air/water connection was put in the spa and if the water creates a venturi force that pulls air in.
If you have a blower and don;t get bubbles with the blower off it does not mean anything is wrong.
