    Default Problem with water spots on chrome fixtures

    I am having a problem with spots on chrome fixtures.
    I am on well water.
    Location: Connecticut

    Here is my raw water analysis:
    Hardness - 21 GPG (grains per gallon)
    Iron - 0.05 mg/l (ferrous)
    Manganese - ND (not detected)
    pH - 7.3 standard units
    TDS (total dissolved solids) - 472 ppm

    My treated water analysis (done by a local lab):
    Copper - none detected
    Iron - none detected
    Manganese - none detected
    Chloride - 11.9 mg/L
    Hardness- none detected
    Sodium - 110.7 mg/L
    Nitrate as N - none detected
    Nitrite as N - none detected
    Color - 0
    Odor - 0
    PH - 7.8
    Turbidity - 0.3 NTU
    Sulfate - 40.5 mg/L
    TDS - 364 ppm

    My existing water treatment setup:
    1. Big Blue sediment cartridge filter
    2. Autotrol 255/762 48K water softener (installed in 2006)
    3. Big Blue RFC cartridge filter

    I confirmed that water is at 0 gpg hardness at all fixtures using a Hach 5B Hardness Test Kit.

    Attached are some pictures. I hope they help in diagnosing this problem.

    The pictures labeled Basement Shower (on the beige tile) show fixtures that have been in service only for a few months.
    The pictures labeled Upstairs Shower (on the white tile) show fixtures that have been in service for a few years.
    As you can see, the spotting/scaling on the Upstairs Shower fixtures is much more extensive.

    On both fixtures, I was able to scrape away some portion (not completely, some spots could not be removed by scraping) of the water spots using my fingernail. I attached a picture of the Upstairs Shower Valve after I scraped it....Does that give any indication as to the source of the spotting/scaling?

    I tried to clean the Upstairs Shower Head valve chrome handle with CLR.
    I put the handle in undiluted CLR and let it sit for about a minute,
    I wiped the handle with a sponge. Rinsed with cold water. But the spots still remained.
    I soaked it again for about a minute. This time, I scrubbed it with a green scrub pad. The spots came off, but it did leave some faint scratch marks on the handle. So, I wont be using the green pad anymore.

    Thanks for the help anyone can provide.
    If you need more info to help diagnose the problem, let me know and I will get it to you....

    Find some one to do a silica test.

    Some of the spots remind of a friend that has a black 4x4 chevy,, mid 70's and it would end up with white spots.. after double and triple checking the softener they he had in place and making sure that it was working and changing out the resin .. the spots continued . That is when we found silica at some thing like 70ppm....

    Hard water spots come off, silica will not or if it does it is often with some thing like a pumas stone.

    Forget about using CLR. Track down a product from Wood Wyant called Zolvex. It is a commercial cleaner used in the food products industry.

    Mr. Moore, any luck resolving this issue?

    I have been doing my research and scouring the forums and this is one of the only posts I've found that seems to match my problem.

    My raw water tests similar to yours (Iron & Hardness, TDS around 500) and I've been running a ProFlo-SXT Softener (new in Sept 2011) and getting this white spotting and buildup all over my newly installed bathroom fixtures. My treated water tests soft and has a TDS around 500. The white buildup left behind tastes undoubtedly salty.

    Any help would be greatly appreciated!!!

    Are you on a well? If so, please let us know what your most recent water testing showed. I assume you had a full proper water test done prior to drinkingthe water or breathing in the steam of an unknown water source. If you have not had a recent test, then their is no answer. Your TDS is 500 ppm, that is not unusual but that high of a tds will always leave spots. If the spots do not wipe off easily and your water is soft, you need to check for silica and other items as well. If the spots wipe off very easily, then it is likely just sodium which is easily dissolved back into the water. Lets see your water test.

    Ditto thanks for the quick reply on this year old thread...I am hoping to find out what this turned out to be in the original poster's case so I have an idea of what to test for. I guess I'm just trying to gather as much info as I can before I start my own thread on this.

    But since you asked...I am on a shallow well (60ft) that was tested for any volatiles during the home inspection. The house was built in the 50's and I believe this is the original well (pump is probably 10 years old). We moved in a little less than a year ago and immediately renovated the only bathroom in the house. Upon turning the water back on, we were seeing iron on the new fixtures/oxidizing in the toilet bowl.
    I had a local well water company come out and perform their on-site tests which indicated the approx. 25 gpg of hardness, iron, and some acidity (this was all they told me). They installed a softener and neutralizer which took care of the iron we were seeing on the new fixtures. In the months following the install of the treatment system, the white buildup has occurred as described above. The well company has been less than helpful with troubleshooting it so I am now trying to learning the mechanics of the treatment system to fix it myself.

    I purchased an HM Digital TDS meter after the well company was out and told me that TDS was low and I knew it couldn't be. The 500 ppm TDS reading is coming from my EZ Meter (@25C). The TDS of the treated water was at 600 but I bypassed the neutralizer which dropped it to 500 from the lack of Ca & Mg being added (no sign of iron so far either).

    I have not had a full metals/inorganics/physical factors test done (I have been looking into that this week). What should I be paying for a full water test? A local lab I checked is approx $400 and I want a raw sample and a treated sample, so would that be $800??

    The water does test soft (from the well company and a test strip I used). The spots/buildup does not wipe off at all with water or clr. Thank you!! Please advise...

    Sometimes high dollar fixes are not the solution.

    Boy, those hand-rub bronze fixtures will certainly deteriorate in no time at all. Simple test is whether soap lathers up all the time, sometimes, rarely, etc. Is the inconsistencies in this aspect of washing? Shut off the water right at the softener and run all faucets to see if any water is still flowing.

    It to me like silica...
    Silica will etch glasses in the dish washer and nothing will take it off, it will leave a white ring in the toilet.

    If it is silica, not much can be done.

    Fork, sorry, I can't answer the chemistry questions.

    What was your raw water pH? What size AN filter and is it upflow (without a control valve) or backwashed down flow? What mineral is in it?

    What size is the softener and what is the salt setting? How many days or gallons between regenerations?

    Are there only 2 of you in the house?

    When someone is in the shower, just before they shut off the water, can someone run cold water at the bathroom sink for a minute or two and then collect a sample to test for hardness? If the cold is hard then you are getting hardness into the water heater but, heating water precipitates the hardness out of the hot water in most cases, so you may not see hardness in a hot water sample.

    Precipitation of hardness in water heater tanks would be so minimal, I would count on that number being significantly lowered on normal water use. Most often the hardness in water heaters is higher than on the cold side.

    With 25 gpg hard water and no softener until a year ago, his water heater is probably loaded with hard water scale. I've seen gas and oil water heaters with scale a few inches thick. And electric heaters with scale build up all but up to the bottom element and elements so scaled up you can't get them out of the hole without a chisel.

    The hardness in the hot water will vary and can be more or less than his 25 gpg in the raw water but probably is less at the end of a shower and that is why I said test the cold water at the sink. If that is hard, he is exceeding the SFR of the softener or past the time/gallons when the softener should be regenerated.

    Fork, why do you have an AN filter when you have 25 gpg of hardness? I ask because I don't think I've ever seen acidic water with that much hardness in it? You said the driller said the TDS was low, which is not a problem. You'd only need that filter if the pH was low; say 6.5 or less.

    If you haven't added the hardness the filter is adding to your 25 gpg in the raw water your softener isn't programmed for all the hardness and will allow hard water breakthrough before a regeneration is done. Meaning the softener will run out of capacity before the regeneration and you get hard water through it until after the next regeneration and then without the salt dose set at the max of 15 lbs/cuft of resin, you'll consistently be getting less capacity until you get hard water all the time. Then if you are using less than the 15 lbs/cuft, you must set it to 15lbs/cuft and do 2 manual regenerations with no water use during or between the two. That's the only way to fully regenerate all the resin. Then reset the salt dose for the capacity you need.

    You can learn more about setting the salt dose at the link in my signature.
