Someone placed a new jet on the spa and air inlet started pouring water out. Enclosing a YouTube video.

Welcome to TFP.

Who is the someone?

The jet is clearly not the correct model for the spa.

Pull out the new jet causing the problem and another older jet and show us pics of them.

Thank you for the reply.
Jets have number 218 6530 on the side. They changed one of the jets. I compared the number to the older one and it’s the same.

 

[ajw22]

Show me pics of the back and side of the jets.

Which one is the old and new jets?

Who changed it?

Why was the jet changed?

Where is the jet that was replaced?

So emptied the spa and jets are working with the water gone. Can there be an issue with the air valve?

 

[ajw22]

Can there be an issue with the air valve?

No, there is a manifold that has holes for the air and the water. The jet is not properly aligning in the manifold to let teh water flow out the jet. Instead the water is being redirected up the air pipe.

Show me pics of the back and side of the jets.

Is there a chance that these ain’t working right and not able to seal?

Ill send you pics of new and old jet. It was fine by a friend. It came out one day and my children lost it by mistake.

 

[PoolIssues1]

These are all the pictures. Have attached the pictures from inside as well.

@RDspaguy you see any problem with the jet?

 

[PoolIssues1]

Not really
I placed the jet in other spots and water flows with air when the outside pressure is less and there is no water, however when the spa is filled with water.. it just comes out of air inlet.

 

[ajw22]

One jet in the pic has two holes, the other has one hole. Which is the new and which is the old?

How many holes do your other jests have?

 

[PoolIssues1]

Some have one other two. I have tried changing the position of the jets with one or two and it hasn’t resolved the issue, so far.
Even with the jets removed, water just comes out of the air inlet valves.

 

[RDspaguy]

@ajw22 has it right. You are pressurizing the vacuum line. The vacuum is created by water flowing throught a venturi built into the jet barrel (the part that comes out). If any of the jets is installed wrong, or removed and covered, it will pressurize. Old worn out jets can also cause this.
It should not pressurize if all of the jets are out, unless a jet is blocked off from the spa side. I have no explanation why it might occur with the jets removed.

Did you recently get a bigger hp pump?

 

[Poolbreh]

I’m wondering if the air intake slit on the back of the old jet broke off and is now blocking Air or restricting flow somewhere in the line

 

[Poolbreh]

I would remove 2 jets at a time, plug air intake temporarily and close off a few jets And rotate. And see if anything moves. I’ve found chunks of plaster before in jet heads.

Did you recently get a bigger hp pump?

I did change to a bigger pump with adjustable speed.

 

[RDspaguy]

That may be your issue, too much pump for the returns. That could overpressurize the jet body and send water up the air line. It will also be the death of your pump. Crank the rpms down a bit and see how it does.
