I just pulled the filter out again and started the tub w/ the top of the filter housing off....I was very surprised to see how little of water was being pumped into the housing. Next I shut the gate valves on each end of the pump, and pulled the plumbing off the pump housing to inspect the inside of the pump. Everything appeared to be fine so I reconnected everything, and when I went to open the gate valve on the pressurized side of the pump the handle came off in my hand... Is it possible this gate valve was previously stuck 1/4 to 1/2 way open, keeping the pump from pumping efficiently? The valve hasn't been touched in approx. 2 years... I'm keeping my fingers crossed that this is the problem. That or I have really bad luck! By the way, its a 1.5hp motor. Maybe i'm just expecting too much out of this thing..... Guess I won't know until I can pick up a new gate valve from the spa store tomorrow. I'll keep everybody posted. Thank you all again for your helpful insight.

Ok, I found a diagram and modified it a bit to show whats going on here. The only powerful jet in the hot tub which I spoke of earlier appears to be the dedicated "ozone injection jet". The supply for this jet comes after the pump, and before the filter. Unless theres some sort of valve that I don't see, the only thing I can think of is some sort of blockage in the water jet manifold. I removed the filter entirely last night to verify there is no difference in jet pressure, and there isn't.......

Only way to shut off the jets is by turning the ring around the jet clockwise..... I believe the jets are removable but I'll have to double-check. I'll play with it tonight and keep you updated. Thanks for the help!

I do not believe this hot tub has a diverter. I know there's no adjustments up top except for the air feed knobs... Would this be down under the tub?

Hello all. This is my first post to this site. Before becoming a member I frequently browsed through other members' posts for information.....I have found this site to be extremely helpful, Kudos to all!! Let me start off by explaining that I have inherited what I believe to be a "dinosaur" of a hot tub. I have a Circa late 90's 6-person fiberglass hot tub, made by Aquatic Industries. This will be my 2nd year as the owner. She's powered by an Acura brand 240v powerpack and a pressurized-type filter. After going for a dunk last night I came to the realization that the jets should be putting out more "umph" than they are.... WAY more. With the water pump on, there isn't even enough power to spin the rotating jets, nor automize any air bubbles into the output of the jet... You can barely tell they're on! I've already troubleshooted the filter which is not the problem. And yes, I've verified that the jets are actually in the "on" position. What makes things even more confusing is that there is one jet in the hot tub, located under the lounger that shoots out over the footwell of the hot tub. This jet is extremely powerful. Unfortunately you can't sit anywhere in the hot tub to enjoy it! Does anybody have any input, or ideas of what else I can check? It's not that I'm not enjoying my time in the tub, but if there is more to enjoy I don't want to be missing out.. Any thoughts or input would be extremely helpful. Go easy on the newbie!! Thank you all....
