It’s been months since this has been changed but I just thought about the fact that the pipe we connected to had been painted before.

Is this white paint leaching into our water?

Any way to tell?

  • the pipe should have been cleaned of paint to ensure a good seal anyway.

    Since you can see paint under the sleeve where the quick connect is, one would assume the pipe is not properly cleaned (even though it is not leaking). So best bet would be redo the connection but clean the area to be fitted before reassembly. You'll need new insert-bushing for the connection to the valve. If you do this, you'll have peace of mind.

    The water flows on the inside of the pipe

The Water is inside the pipe. The fitting you have on the left side connected to the painted pipe should be making a tight leak proof seal there should not be any paint at the point of inner seal. If you are concerned - remove the connection and sand the paint clean it and remove it then reconnect your fitting.

If the paint is lead based - you can try a lead test. Be forewarned that what is coming from your utility will probably be more than what you have from that paint area if anything at all.

Paint is not leaching from the outside of the copper to the inside of the pipe either.

Just thought I would add this picture to help you - see the insert sleeve that fits on the inside of the pipe - the white nylon piece. This seals the inside from the outside.

Shark Bite Fitting

  • Thanks Ken. Makes me feel better. I was just thinking that part of the painted pipe slides into the shark bite, so the outside becomes part of the inside.

  • @Ryan updated my answer with a picture to illustrate that you have nothing to be concerned about..
