  1. I bought a new ozonator and installed it, no problem... I had one of the restrictors left over so I stuck it on the input side of the ozonator. It makes the bubble smaller ad I can tell you it's not going to clog. I'm happy!
  2. Hey I was so frustrated I called the guy back. After further prodding I was able to get to the bottom of this. I swear some tech support people have little knowledge of the English language. They didn't switch to a new magic system that does not have the gunking up problem... Rather they changed the way it's configured. They no longer put the restrictor on the output of the ozonator, they instead put it on the input side. No brainer when you think about it... He also shared the part number. 6473-124A. So there it is. Mystery solved. Pfft... New ozonator system indeed. lol
  3. Looks like Jacuzzi has changed the way they use the restrictors. They tell me they are now putting them on the input side of the ozonator rather than the output. Makes sense. I think I may have solved my PH drift. I think one of the check valves was defective, had a leak that was pulling some oxygen in. This would certainly raise the PH as the filter pump runs 24/7.
  4. Help out a guy with the terminology. I assume I have a CD one now. It used to make a high pitched noise. So the UV one, does it kill by running water past the light, or does it still make bubbles? This is so frustrating. Called Jacuzzi tech support. Told them my ozonator went out. The guy tells me "they are using a new one now that doesn't gunk up with brown acid." However he later told me the tech would not give a part number! Told me to go to a dealer... So, no part number, not even a description. Why is it when it comes to hot tubs, no one seams to have any freaking idea what the hell they are talking about!
  5. Seriously! No one knows what range the temperature varies in their hot tubs! I mean you open it to use it, and there is a temperature displayed... You have to check it before you get in right? What temperature does your hot tub range from the selected temperature?
  6. Tub: Jacuzzi J-345 50th anniversary model Capacity: 336 gallons Ozonator: Yes Jets: 27 Power: 240vac @ 60amp, can run pumps and heater at same time. Circ Pump: Yes Use: Year round, once every weeknight, sometime twice a day on W/E by two clean average size naked humanoids. Last week we had a storm and it killed my outside light and my Jacuzzi's ozonator. I was chatting with the Jacuzzi support guy. He told me the ozonator originally used on my tub had a problem of gunking up with brown acid, and they now install a new design that does not have that problem. I asked him for the part number but he could not find it. I am an Electronic Engineer and can replace this myself, but I have no idea what to get. Can anyone shed some light on this problem? The ozonator it has now is a blue box smaller than a shoe box. Two ports, one unconnected and one with a long 1/4" tube. There are two check valves, with a flow restrictor between them, and then it connects to a fitting on a larger tube. Help me please. I don't trust it without the ozone. Thanks, Jim
  7. Well I called the number and chatted with a friendly guy named Rick. I submitted my argument, the wide temperature range, and the filter cycle loosing time. I also went into some detail about the fact that I have replaced the 30 amp slow blow fuse inside the box 5 times. And the fact that the bad temperature sensor was causing the heater relay to constantly cycle whenever heat was called for. (extra wear and tear) He pretty much shut me down on everything. His spiel... (The filter cycle is not on an actual timer. It uses an algorithm to set filter times and it's not out of the question for them to be off by a minute or two.) I do not believe this. It most likely uses a software based timer, and if the electronics (crystal or ceramic resonator) is off causing the timer to loose time. His speil... (The high temperature, 105, is probably due to secondary heating, if the filtration cycle is running at the same time the heater is on.) I know this is not the case. I can open it in the middle of the day and see 105. The filter cycle is normally around 7:00. Why when you want 103 does it continue to heat to 105? The PID for the temp control is not right. Period... Again people. You know who you are... Can anyone chime in here with their experiences concerning temperature variations in your spas? What is normal? I can't accept that it's normal for a tub set to 103 can be anywhere from 101 to 105...
  8. I have had my Jacuzzi for three years. Just last fall the thing was going into safe mode so called for service. The guy comes and replaces the temperature sensor. Seams it was bad from day one. This is what it was doing from day one... Set heat to 103. When temp drops to 102 the heat comes on. Heat is on for 30 seconds, OH is displayed and heat is turned off. A minute later it comes back on and repeats. Eventually the temp goes back to 103 and the heat turns off. So the guy changes the temp sensor and all is well... Except this is how it works now. Set heat to 103. When temp drops to 101 the heat comes on. Heat stays on till temp reaches 104-105, then turns off. Heats up much faster now. But it's practically impossible to predict the temperature. It can be anywhere from 101 to 105. Another issue is the timer loses a minute per day. For example set it to filter cycle at 6:30 and the following day it starts at 6:29, then the next day it starts at 6:28. Losing 30 minutes per month. Can others with a similar tub comment on how it works for them, cause I have apparently never had it right from day one.

  9. Really... Below quote from a chemist friend of mine. He didn't know the restrictor was made from plastic, but you should get the idea. Nitric acid seems a little far fetched! Wiki ref. Nitric acid (HNO3)is a highly corrosive and toxic strong acid. This is the stuff you once used in High School Chemistry class that will dissolve copper pennies. It is very corrosive on metal surfaces and particularly corrosive upon ferrous metals. I suspect these are Nitrous salts, Wiki ref. Nitrous acid (molecular formula HNO2) is a weak and monobasic acid known only in solution and in the form of nitrite salts. It makes more sense that these weak acid salts result from a small proportion of the normal atmospheric nitrogen that gets oxidized by the ozone generator. A basic solution such as a household drain cleaner should work to clean this such as "Drano", "The Works" or "Liquid Plumber". These are strong basic hydroxide salt solutions such as sodium hydroxide. Aluminum is one of the few metals that can be damaged by basic solutions. One cheap way to make hydrogen gas is to dissolve strips of aluminum foil in a warm solution of sodium hydroxide. Do this in a plastic soda bottle and you can stretch a balloon over the mouth and watch it inflate. Unfortunately, hydrogen gas is highly flammable so this neat trick can be kind of dangerous especially if anyone around you is smoking at the time. So if the restrictor is not made out of aluminum, then try soaking it overnight in one of these dilute solutions of drain cleaner. Wear some disposable dish gloves and thoroughly clean the thing after soaking. Ozone and Nitrous are corrosive oxidizing agents so eventually these things will cause corrosion to the point of mechanical failure.
  10. To Peteyboy, I apologize for my crass comments. There was no reason for it. To James, I was adding PH down every 2 to 3 days to keep the PH below 7.9. This went on for 3 weeks. I received and installed the restrictor and had a stretch of 3 consecutive weeks where the PH bounced from 7.6 to 7.7. That is the ONLY thing that changed. I continue to have a rock solid steady PH of 7.6 to 7.7. I use a highly accurate electronic drop tester. The tub is balanced using ChemGeeks bleach method. You can say what you want, but I'm never running a full flow ozone system again. Your mileage most certainly will vary.
  11. I guess your customers don't bother to check the PH then. I'm telling you I have proven this with accurate data logging. Your reply is your nose is big? Whatever...
  12. Yeah, about a year after I got my Jacuzzi the ozone bubbles stopped. The repair guy told me "I was told to just take these out if the tub is in a vented room." Well he did so... Well that certainly did fit it. Lots of bubbles now... After that day I had problems with the PH raising... It drove me absolutely mad! When I finally figured it out I had Jacuzzi send me three of the things and the PH has been spot on from then on... I keep a very tightly monitored hot tub. Keep a journal and have a record of the last two years. Removing these restrictors really &*#$ up the chemistry... If you are yanking these restrictors out, you are not doing your customers any favors at all! So what's clogging them? The tubing is full of a very sticky gunk. What is it? I have not tried to clean them with some sort of solvent, but I've got three of them to try and clean. They charge $20.00 each for them.
  13. Yeah, that's basically what I've been doing. Just not on purpose. lol Well at least I mastered the saturation index... 8) Thanks for the reply.
  14. I read that post with great interest. FYI There is another source of irritation that wasn't mentioned. If you have an ozonator, they usually have a restrictor inline to keep the bubbles small. If it is removed (bad repair technician, bad...) the result is significant PH drift upwards. But it also irritated (burned) my skin! On the backs of my calves where the filter pump outlet sends a stream of ozone "bubbles". No where else was my skin irritated. But for the longest time I didn't connect the rash with the ozonator issue.
  15. Curious, what sort of health issues? Side effects?
