Ozonator - Worth Repair It?

[Aqua Therapy]

I took over pool maintenance about 3 years ago. One of the issues I found (other than high CYA but a whole other story) was my Del Ozone EC-2 had not worked for years. Until now, I had put off dealing with the Ozonator due to other pool-related priorities. I found an upgrade kit for $350 plus I'll need to replace the tubing. Since this thing hasn't worked for at least 5 years, I tend to agree with others the cost/benefit just isn't there. I need the wall space to mount a new chlorine pump so is there any reason why I shouldn't remove the Ozonator and trash it?

Assuming I don't need the Ozonator, could I use the manifold barbed injector for chlorine?

Trash the Ozonator.

Ozonators are all but useless in a residential outdoor pool. At the very best case, the ozone only affects the water that is flowing through the plumbing and then, once out of the returns, it simply bubbles out to atmosphere. Given how poorly circulated and homogenized pool water is, the ozone is contacting less than a few percent of the total water volume. It’s really unnecessary.

Good question. I would think you could, but the educator will pull the chlorine into it. So not sure if that will effect your chlorine injection pump or not.

Just what I thought. Off to the trash heap it goes (unless someone pays shipping for an old dead carcass ).

I’ll experiment with using the manifold as my chlorine injection point. Once my new chlorine system is up and running, I’ll post a separate thread about my installation.

The Venturi injector will constantly pull in liquid chlorine unless you install a valve to shut off the supply from the tank. It’s really meant for gas injection. Liquid injection systems just need a good peristaltic pump and a check valve/injection valve.

You could use that Venturi injector for a CO2 injection system which would be used for pH control as CO2 is acidic when dissolved in water.

I’m using a Stenner 10gpd pump. I thought, perhaps erroneously, the pump would provide some “shut off” to any positive or negative pressure caused by the manifold.

Given the Venturi effect is meant for gas, perhaps my best “easy” fall back is to cap the Venturi and use the drain of the unused tablet chlorinator. Of course, I would need to clearly mark it with a warning not to use tablets unless the liquid system is turned off.

Sounds like a future project is to remove the manifold and replace it with a better injection point down stream of the tablet chlorine (which I want to keep as a backup).
