My Ozonator seems to have developed a leak at the tube adapter. It only seems to happen when the equipment is offer. If the equipment is on and the ozonator is pushing air into the system, no leak (i assume because of the positive pressure generated by the ozonator). I have new tubes, check valves, and tube adapters on order. And just in case it was something else - i pulled the tube adapter, removed the existing teflon and reapplied that as well. The drip persists. I know these are annual maintenance items but am I missing something obvious that I should check or do?

 
QQ - my pool is a flooded system where the pool itself is at a higher elevation than the equipment. While I have a valves that can isolate equipment between the drain lines and the return lines - my ozone port is below my last return valve. Consequently, when I remove the ozone tube adapter - the full weight of any water in the pool / return lines sprays out. Its manageable - but id rather not get drenched if i can help it - at least in December. Is that just something i have to deal with?

Put rubber plugs, like the type used for winterizing, in your returns and skimmers.

You have a venturi, which should pull in air while the pump is on.

Assuming that the ozonator does not have a compressor, the part should not leak if the pump is on.

What is the ozonator model?
 
Also, if your equipment is below grade then that ozonator line should have a low spring force check valve on it to keep water from backing up into the Venturi line when the pump is off. You could be inadvertently flooding the ozonator with pool water.

Also, ozone is unnecessary in a residential outdoor pool … but that’s a different conversation.

Del Ozone 25. It definitely does not leak when the pump is on. for the next couple days - it wont leak as I'll have it in freeze protection and to your point, and it wont leak when the pump is on.

It has a white and black check valve (this one) not shown in the video about 6" or so from the tube adapter.

And I'm with you on ozone being unnecessary. In this particular instance, my only concern is the leak. it's something I would not buy again if I had a do-over on my pool build (along with auto fill.... but that too is another conversation! and i likely have an unpopular take) When the modules wear out, I won't be replacing them.

Maybe it was a loose clamp or maybe a crack that was difficult to see.

Try pushing on the barbed part to see if you can see a crack at the base.

In any case it was a defect of some type that had to be addressed.

It's possible that you could have removed the tubing and reinstalled, but if the barbed part broke during the process, then you would need the new part anyway.

In any case, I would get rid of the ozonator as it is not doing any good and it can actually cause problems like destroying chlorine and oxidizing metals like iron to cause iron stains.
 
Looking closely at the video I can now see the clamp on the hose a little better. Those plastic tube clamps are about as cheap and useless a clamp as you can get. The manufacturer clearly didn’t care to use something a bit more sturdy. Those plastic clamps, left out in the heat and sun, will lose their clamping force pretty quickly and they certainly aren’t suited for potential pressure application if the check valve fails. A better clamp would be a standard metal band clamp that you tighten with a screwdriver or even an automotive style metal spring clamp. But that plastic clamp that’s on there is worthless.

As in: you wish you had an auto fill, or you wish you didn't?

I’m generally a fan of replace anything that csn easily / affordably be replaced while you have something apart. It wasn’t particularly easy to remove that tube, and I certainly didn’t want to have to do that part twice. :)

I hear you on getting rid of it. Mentally having a hard time just ripping it out at this juncture as it’s brand new. But I hear you.

Fair point. I’ve never seen that type of plastic clamp before, and it certainly felt flimsy. I’m shocked I didn’t break one during removal / reinstallation.
