Hi all. After some lengthy research on the interweb (and even bugging the local Jacuzzi tech,) I decided to turn to you all here. Background is I just purchased a 2009 Jacuzzi J-345 a couple weeks ago. I put the old 1998 D1 Diplomat out of its misery (who knew I would enjoy taking a sawsall to it?) I have to say for a middle of the road hot tub, I am highly satisfied with the J-345's performance. Without going on a tangent, I feel Jacuzzi has an effective, powerful spa in the J-345, that's well thought out as well. Things seem to have come a long way in 10 years.
My question revolves around the air injection system--perhaps an owner of a J-345 or one of it's closer models can chime in here? There are 4 air injection toggle switchs, each controlling the jets to specific seat. The 3 farthest from the main pumps work AMAZINGLY well. When they are turned on, it's like hitting the turbo boost button on the jets. For a passive system, it's quite impressive. HOWEVER, the 4th toggle switch (on the side where the control panel is) doesn't seem to make a difference--the jets are so powerful it seem like the air induction is ON all the time. There is such a difference between this air injector and the other 3, that I immediately thought something was broken.
I took off the bezel to the offending toggle switch and it sounds like it's working--ie, I hear the rush of air when its open and it seems to stop when the switch is closed. However, the pump2 is single speed on high all the time, so there is alot of ambient noise. If i had to guess, I believe the switch is not defective.
Question: Is this normal operating for this 4th air injector? Are other Jacuzzi owners finding that 3 air injectors work great, but the 4th closest to the pumps doesn't have near the impact the others do. If this is the case, so be it. But if there is something wrong with the 4th injector/toggle switch, I want to get it resolved.
Again, the issue is that the air injection doesn't seem to turn off at this specific seat. The jets in that seat are going crazy all the time. Would the close proximity between the switch and Pump 2 be a possible reason it seems like the air injection is on all the time?
Thanks in advance.
