Spa jet??? What is this?

[emdoller]

Hi

I'm trying to figure out my spa plumbing as I try to find a leak. In the corner, between the spa fill during normal filtering (above and not pictured) and the heater return (below) is a jet. I thought it was a normal jet as that's what it looks like but no water comes out of it when I turn the jets on.

Any idea what this could be?

Do you have an auto fill? Equalizer line to the pool?

 

[emdoller]

Yes, I have an auto fill on the pool. I also just noticed one that looks like a jet in my pool below the spa. They can't be connected or the spa would drain into the pool. I always thought the one in my pool was the suction for my waterfall. I guess I should have paid attention when it was built.

Yeah if the spa is higher than the pool, it would drain down to pool water level if those ports were attached.

So I'm not sure what it is.

Could it be a make up jet that adds a little water to the spa when in pool mode?

I'll run it in all modes to see if I can figure it out. I'll get back to you.

Pictures of the plumbing setup at equipment pad could help. Need to see the valve setup, is the spa draining when system is off and then fills when it comes back on?

I figured it out but not sure I understand.

The "jet" one in the spa is another inlet like the bare one above it. So when I turn the filter on, water comes out of both of them and then dumps from spa into the pool. Why the need for 2??

The one in my pool is connected to my waterfall. I assume it's there to make sure if I turn the valve near the waterfall to restrict the flow the makes sure I don't burn out the pump. Does this make sense?

Thanks!!

With no pictures of the plumbing, hard to say

 

[emdoller]

Sorry about that. Here's pictures.

First one is a better picture off the spa. Second and third shows pool equipment.

So water comes out of both ports labeled pool fill in the spa when running on pool mode? That one seems almost above normal water level.

Yes exactly. Not sure why that is. I always knew it came out of the top one because it's high and you can see it. Never knew about the bottom one.
