Problem with water spots on chrome fixtures (PICS)
I am having a problem with spots on chrome fixtures.
I am on well water.
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 (in order of water flow):
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 show fixtures that have been in service only for a few months.
The pictures labeled Upstairs Shower 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.
UPSTAIRS SHOWER (in service for a few years):
DOWNSTAIRS SHOWER (in service for a FEW MONTHS):
AFTER SCRAPING OFF SOME OF THE BUILDUP on UPSTAIRS SHOWER:
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. 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....
