    This is not uncommon. Have you tried actually using a Jacuzzi tub cleaner? They are available at the big box home improvement stores.

    Actually I didn't know there was a cleaner on the market for that. Thanks...I'll give it a try.

    do you know if these black "specks" are "soiling" or could they be "gasket" type rubber bits? If they are bits of rubber you may be losing some critical "sealing parts" of the pump assembly. Old rubber bits tend to dry out an crack, eventually they can fail. I would take a peek inside the service access panel to inspect the pump, fittings and plumbing for leaks. Better to catch a leak early then later after prolonged water damage can ruin sub flooring etc.

  • Jacuzzi tubs can discharge all sorts of stuff. They tend to build up a bio film that even bleach will not remove. What is happening is soap scum, hair, skin cells and a bunch of other things I will not say builds up within the pipes even after you drain the tub out. The result is as it sits there it begins to develop a film that grows. If you leave the tub empty for several weeks this film dries out and begins to flake off the next time you use the tub. Using bleach does not kill this bacteria as one would think, but it does loosen some of the surface material and cause it to flake off every time you use the tub. You need to heavily chlorinate the tub and pipes. let it sit in the tub for several hours while the jets operate. Be sure to ventilate the tub area when your doing this as the chlorine gas will become quite powerful. Also using Algacide that is used for black Alga in swimming pools will also be required to kill off this bacteria as bleach or chlorine by itself is not enough. You can get that at any pool supply along with the chlorine. Bleach in a bottle is not strong enough to use alone. Hope this helps.

      We have the black chunks coming out when using the jets. My husband is trying to tell me if you don't turn the jets on its ok. He keeps getting skin rashes and won't listen who does that? Can the professional jet cleaning stuff really help? I use white vinegar to flush out the jets with hot water.

    Wow, now I think that might do it. We have a swimming pool so I think we have the algae killer...I'll go get a small thing of chlorine from the pool store. We have a salt system in our back yard pool...I definitely will share this with my husband. I hope it works...I love my tub, but the gunk has gotten me a little grossed out. :)

  • Here is one of many links on this topic. http://www.spavelous.com/EB/N081017/Spa-Sanitation-01.html If you think the gunk has you grossed out. Do not read it.

    Thanks to Woodbridge, I have read a couple of your articles and there are very interesting indeed. I purchased today...a product that is safe and suppose to clear out the gunk from the pipes. It's called AAAh-Spa. I did a little research and read the reviews and found them to be reliable. Plus it's safe for septic systems. I will post with the results, I should get the product on Friday. Thanks again.

    Meant to say they are very interesting... typo. oops.

  • Just be sure they warrant not damaging any seals on the tub. From my understanding of this topic, nothing even regular cleaning after each use prevents this bacteria from forming. Some test results showed regular use of a tub, which did not have time to dry out between uses when the left over gunk would have time to dry out. Showed higher levels over time of airborne bacteria in the air that was typically found in the pipes when swabbed and tested. Jacuzzi brand tubs were sued several years ago because of this very issue. Not sure what resulted as I did not follow it to closely, but what ever you do, clean, clean, clean. every time you use it.

    Your theory of the biofilm drying out and coming off as flakes isn't true. I have the same flake problem on initial use, after completely draining the tub, and my tub is used Tues/Wed/Thur. Renee B - how did the AAAh-Spa work.

    Don't use bleach! I learned the hard way, as it corroded my rubber seals in my whirlpool tub. After that costly repair, I found a product called Plumb Clean on the kitchenbathsinks.com website. It has worked for me and got rid of the yucky black flakes. I was told that the water settles in the plumb lines of the whirlpool tub and grows mold and bacteria and that's what you see sometimes when you run your tub. Gross! I haven't seen any of that since I started using Plumb Clean over a year ago.

    I learned this while living in Japan. Always take a shower first to get clean. The tub is for making you feel relaxed while reading, listening to music or soaking your joints if you have that problem. There is a sponge thing you can buy that floats on the water and grabs hold of any grungy stuff.

    Have your hot water tank cleaned and inspected.

    When I had a tub I use to use Tang Drink Mix (read about it somewhere). It worked well was cheap and the odor wasn't bad! Fill the tub add tang run the jets and then drain and rinse with clear water (and run through the jets). Cleaned it great and as my kids used the tub too I wasn't worried that their delicate skin was absorbing harmful chemicals!
