I own a Sundance spa, and ever since my first fill-up, only one set of jets worked at full force (There are 4 jet sets total). The remaining 3 jet sets have a very very weak flow; almost undetectable. The jet controls are manual and open/close via turning knobs.
I was not given any information in regards to tending to the spa so I had never filled the tub up through the filter (Which I now understand to be the proper way). Because of this, and the fact that the jets have not worked upon arrival, I am assuming this to be a user error (such as trapped air) as opposed to defective parts. I have read the post on bleeding the spa, however, the instructions were not clear to me:
First he says there is water in the spa, and that is how you recognize the pumps are not working. But then he says, "There is no water in it"... What? So how would water "begin to flow in"?.. Am I supposed to empty the tub and begin filling it up again with the power on and the union or drain pipe loose? Is it ok to turn on my tub without there being water in it? Just don't want to damage it if I am misunderstanding the instructions Note: I did loosen the drain pipe and let water out but jets still are not flowing strong.You want the water to drip from the fitting, maybe pour, but try to use one that will keep water away from the control pack and the back of the pump. DO NOT DISCONNECT IT COMPLETELY. Just enough to let some water or air out. Otherwise you will get more water than you bargained for. Got it? Now tighten it up and let's do this thing for real. Turn the spa on and the pump on high. There's no water in it, so don't go inside and make a sandwich. Go back to your union/drain plug and loosen it again. As water begins to flow in toward the equipment you will hear the force of the air and water coming out increase. That's your cue to start tightening.

Here are some photos of my pump and 3 of the jet sets (The working set is the one in the middle with the smaller jets). My tub is a Sundance Denali.
Any ideas? I would love to get the pumps back working at full force!
