Hot Spring Watkins Replacement Spas Freshwater III Ozone System Complete, 72602

Easy to install. Works better than the original Hot Springs ozonator. Comes with everything you need to make a quick install. Water is crystal clear and smells much better with less chemicals.

This is as expected, the exact original spa part. If you don't have to replace the plastic "T" component, then a straightforward replacement. Fortunately, the existing "T" and attached clear 1"(?) tubing was ok. On my Jetsetter model spa (Hot Spring Watkins), it would have been a difficult job to replace it as these components are between two large mechanical components and one of them would need to be removed in order to replace the 1" tubing with "T" connector and fit back together. And doing such work on your knees or laying down-quite awkward. I hope none of you have to do this additional work!

OEM replacement for Ozone generator. Works as expected.

⚠️⚠️⚠️⚠️DO NOT EVEN THINK ABOUT BUYING THIS PRODUCT. The warranty is such a fake. I doubt this is even a real Watkins. This product lasted 1.5 years. The warranty itself was an insult to my spa. Now needing to find another replacement after the hassle of taking that piece of junk out my spa. Spend your 300 dollars on something that’s worth your life. Now mind you, you may not believe this review with no picture evidence but trust me. I AM NOT WASTING ANOTHER SECOND OF MY LIFE ON THIS ITEM. ⚠️⚠️⚠️⚠️

In case anybody else needs to install and goes through the same thought process as me ;-) The ozone bubbles stopped in my Hotsprings Limelight Pulse (circa 2020). Figured it was now time to change ozone (they had told me it'll last 3 or so years, so got my money's worth). Product arrived quite promptly. Turned off the power, opened up the front. The old unit was a corona something or other, big white box dangling from tie wraps on the left. There was a very long yellow tube from that looped behind the control box and over to a T in the bottom right corner. I didn't drain the tub at all, so figured maybe it was just the old corona unit that was bad. Pulled the cover of the controller, disconnected the wires (there was an "extra" ground on that connector). Cut the incoming tube at the old unit as the yellow tube looked pretty good and figured it would be an easier install that way to reuse it. This is the first problem. Getting that tube onto the new unit was a PIA. I don't know what the connection is that comes out of the new unit, but it seems to be some sort of initial plug inserted into the unit with another adapter tie wrapped onto the end of that one. Pushing the yellow tube on to that flared end was not easy. I tried soaking it in hot water, flaring it out a bit with a needle nose, etc. The problem is you can't really just push it and rotate because the other connector moves around. You have to grab both, keep the one attached to the unit still, and try to maneuver the tube on there. Eventually, it went on. Fired the unit up, no bubbles. Grrrrr. I couldn't hear a hum out of the new unit, so got a voltmeter out and yes there was power there. So figured maybe the old tube was not great. The T that came with the new unit looks smaller than the one that was installed already, plus I didn't want to risk cutting that big ol' tube to put in the new T. Luckily, the connector to the new T is the same as the old T. So I unscrewed that one from the new T (with the new hose on there). I unscrewed the old one and noticed I couldn't see down through that connector to the old T. That was all clogged up (and a small amount of water started coming out of course). There is a small grommet/plug with a small diameter hold in it for the ozone to enter the T. I pulled that out and it was all disintegrated. So perhaps my old unit was working still, but couldn't push ozone in. Regardless, it was time for a new one anyway. The new T had the same grommet installed, so I popped that out and put in the old T. Fit perfectly. I could have tried to reuse the old yellow tube, but that didn't seem right at this point. The next small problem was that the connector onto that T isn't free spinning. As you try to screw on, the entire tube spins. I had spent a bunch of time getting the new tube pushed onto the new unit (grrr, that connector!) So, I had to pull out my newly installed unit so the entire assembly could spin while I installed the new tube on the old T. Then got everything back together by feeding it back behind the box, etc. Fired it up and out come the new bubbles! There was only enough tubing for a single loop behind the box, but that was fine. 4 stars because of that connector on the unit and the PIA getting that hose on there (with no instructions for how to do that any easier), and I really think the T is too small for the tube diameter it could have replaced. Sorry for no photos, but I had to button it all back up before I thought about it.

I had trouble with my water being murky and yellowish. We changed the water and it went right back to murky and yellow, but didn’t stink. We we to the dealer and they gave us other chemicals that didn’t help. So l ordered this replacement, it is the exact same as the original one. When I took it apart the injector T was plugged up, there is a rubber grommet that fits in it with a hole to inject the ozone, it had disintegrated and plugged the T clear off. The grommet is probably a .50 cent item. I replaced everything and cleaned and refilled the tub and it went back to working fine. So check the T and if you can find the grommet, pull the T out and clean it with an air compressor it will save you a lot of money.

This is a genuine Watkins Wellness ozone generator. I have use it for about a year. It is much better than the after market generator supplied by my dealer! I have a 250 gallon spa used twice per week and rarely need any sanitizing chemicals or chlorine. The price is significantly discounted compared to dealer retail price.

Pretty easy install. Since the Jacuzzi was empty at the time, all I had to do was cut the line and put it in. There are a couple of install videos on YouTube that you can watch. Works great.
