Greenish white chunks clogging faucet aerator


Change the faucet. It is cheap brass in the faucet that is de-zincafying. A combination of water conditions and flow volume cause the brass to break down. When it does there is a white powder ( zinc mostly ) that scrubs off and clogs your faucet. Moen.....strikes again

The vinegar test will tell what it is; fizz means hardness.

For some reason I didn't see that.

Then since it floats it's not brass corrosion.

I don't know what they use for dip tubes, but I know a little about plastics. There are two main categories for plastics. The first is called "thermoplastics" like polyester that soften and melt when you heat them and then harden when you cool them.
The other category is called "thermosetting" like epoxy and bakelite. Once it sets, heat will not melt it. It will eventually fall apart if taken to too high a temperature, but will not melt.

So just because heat does not melt it does not mean that it is not plastic. And if you think about it, if you were going to put a piece of plastic into hot water for 10 years, a thermosetting plastic might what they choose.

Greenish white chunks clogging faucet aerator


Hi,
First time poster. I found this forum while trying to find a solution to the same problem. Since I didn't find an answer at the time, I moved on.
But now, thanks to my Dad, I might have an answer. He gave me a supplement insert he got in Popular Mechanics and there was a Q&A with this very question. According to their answer, the blue-green-white chunks are aluminum hydroxide caused by a high (8+) pH in the water reacting with the aluminum anode. They say replacing the aluminum anode with a magnesium one will fix this.
I searched their site and did a general Google search and could only find this article (nothing on PM site).
http://www.hot-water-heaters-reviews.com/anode-rod.html
Good luck and hope this helps.

Thanks again everyone for the advice. As it turned out, the Moen faucet was causing the problem. Once I replaced it, no more problems. Even though it was only about 5 years old, I removed the faucet that was getting clogged, pulled it apart and saw some severe rusting and corrosion on the inside of the faucet. I didn't cut it apart to inspect the inside tubes on the faucet, but the outside of the tubes was really bad so I'm sure it was on the inside too.

I wasn't happy that this new of faucet was already that rusted/corroded (we have big city treated water with no iron in it), but was pleased with Moen's customer service. They sent a new one for free to replace it, since it has a lifetime warranty, and the problem is solved.

Everyone says Moen has a great warranty, great customer service and backs their products, and I see why now.

Thanks for letting us know and glad to hear you fixed the problem. Contrary to Mr. Slussers post which I am sure he will continue to argue, Moen faucets are prone to that particular problem. Those of us that do a lot of plumbing service run into it all the time.
