bluegreen water stains

i recopper piped my house about 4 years ago. now i'm getting a bluegreen stain around the waterline of the toilet. its not just a wipe it off stain. there is an actual buildup that needs a lot of elbowgrease to remove. i do have culligan water treatment but not for the toilets. by filling a ceramic bowl from the culligan source and let it sit, i get the same thing. kind of eliminating that being the problem. the water co. says its cheap copper pipe. all the nipples coming out the wall are brass. copper main from the street. any clues?

Got any idea what the pH of the water is?

no i don't. but none of my neighbors have this problem

Is the water chlorinated? Do your neighbors have any kind of water treatment serving the toilets?

You may not have done yourself a favor by running un-Culliganed water to the toilets. When I put in my water treatment system I initially thought it'd be a big waste of treated water, and planned on plumbing the toilets seperately. A wiser man than I told me that toilet mechanisms and bowls like clean water just as much as we do, so I ran good water everywhere and I haven't regretted it. Intermittent problems I had with a PA toilet have disappeared, and the bowls look clean enough to drink out of (at least our cat thinks so).

like i said i get the same results with or wothout culligan

Sorry, I missed that. Have you asked Culligan for help?

blue green-

its probably the type of soldering flux you used back then.

If you used LACO it will do that....

some other fluxes will wash out with a blue green tint to it....


if you are on a well, you could clorinate the well

turn the water conditoner to by-pass and then turn on all

your faucets and pull up the dilluted bleach through all the

pipes and then let it sit for a while....


you got to fill the heater and wait till you can smell it

in the hot side of the faucets.....


the longer you can let it sit the better...

that should clean it out

it will either fix the problem or make it worse for a while...

ok..i don't know what kind of flux was used. plumber is long gone. lol probably used that and thats why he's gone. if so is there any way to remedy the problem?

Blue/green staining is usually caused by copper in the water, so have the water tested for copper. Low ph, less than 7.0, causes copper corrosion which adds copper to the water and probably caused your repipe job to be necessary.

All the water in the house except the outside faucets should be treated.

There is no such thing as "cheap copper" tubing so call the water guys back and tell'em so and ask why your water is doing this. They won't tell you if they know but you'll show them you don't believe their BS and put them on notice.

What type water treatment do you have from Culligan? A softener, an acid neutralizing filter?
