Hello! I'm new to the forums. I recently acquired a 2009 Barefoot Spas 77LP hot tub. After getting everything wired up and spending a few days getting my water chemistry right (this site was a huge help the water chemistry) I noticed a few issues. We got in for the first time yesterday and I noticed that the air intake for the waterfall feature (and one of the other air intake valves) was spilling water.

After looking around online some, it seems like this is due to a leaking jet or an improperly installed jet? So, this morning I went to open up the cabinet and see if I could find a leaking jet. I did not find a leaking jet, but I did notice that the ozonator is leaking:

So again, I did some internet research. Since this leak only occurs when the hot tub is off (jets off) it seems like the solution is to replace the check valve (and possibly the Mazzei valve? not really sure what that is). Here is the picture of the line where the check valve is:

As you can see there is a black check valve and another white valve. So, here are my questions for y'all.
1.) Is there a difference between the black and white valves, or are they both just check valves? Can I just order two 1/4" ozone resistant check valves and install them here, or do I need to get another type of valve?
2.) Is it possible that the leaking air intakes are related to this? If not, what's the best way to identify an improperly installed jet if nothing is leaking underneath the tub (there is very little insulation in the cabinet and I can pretty clearly see that none of the jets are leaking underneath)?

Thanks in advance for your help!
 
@RDspaguy, I read on here that maybe you are the guy to talk to, if you get a minute.

Also, is there an easy way to identify where my air system check valve is? Maybe that's the issue with the leaking air valve(s).

In case anyone ever looks this up in the future, I got it fixed! I replaced the ozonator check valve and that stopped the leak coming from the ozonator, but did nothing for the leaking waterfall air intake. One down.

Next I started checking all the jets (turning them off/on, checking to make sure they felt secure, etc), and found one of the big 4" jets on the bottom of the tub felt loose. As I was fiddling with it, it popped out. Broken plastic tab, so I ordered a replacement jet (which just came in today). I went out and installed the replacement jet, but that also did not fix the waterfall air intake leak. Boooo.

So, after turning off the power, I unscrewed the waterfall air intake to see if there were any parts that looked obviously broken. After taking it apart I didn't notice anything weird looking, so I put it back together and noticed that one of the pieces screwed on MUCH more snugly that when I had taken it apart. Turns out one of the pieces holding the housing together had just gotten loose during the move. After putting it back together, the leaking stopped. Win!

It's powered back up now, with no leaking ozonator, no leaking air intake, and a new foot jet. If anyone randomly finds this in the future I hope it helps.
