Does the water volume in the irrigation pipe increase when the spa is running vs when the spa is idle?

During this test were spa valves set to spa only?

Does the water stop flowing out of the irrigation pipe when the water level is below the spa jets?

When you had the spa valves turned to the off position, did the spa still lose water?

Is the equipment pad higher or lower than the pool water level and if so by how much?

When you opened the filter bleeder valve and the water stopped in the irrigation pipe, where was the water level in the spa?

Sorry about all the questions but I am still not following your comments.

Already paid Leslie's pool guy to unclogged the nozzle. Let's see if that does anything to the water drainage issue, doubt it but hope it does.

Mark,

It is ok, I appreciate that you're trying to help. He told me to replace the Jandy valve that control the water coming from the spa. I will do that and see. He also said just let the water go down by itself in the spa until it stops and see where the level is... which might tell me where the leak is. Make sense. I'll do what he ask and see.

Thanks.

I would be curious to see if the level is the same as the pool level.

I would still be interested in the answers to the questions I posted above. But keep in mind that the spa may go down to pool level but not beyond because of other issues in the plumbing. Water seeks it's own level, so if the level that the spa settles at is the same level as the pool, the leak could actually be below that.
