Tub faucet iron sediment - for past 3 months
Hi. I've read similar posts but my problem seems somewhat unique, and I'd appreciate any feedback.
About 3 months ago I renovated my shower, which included some plumbing work. I did place a new galvanized steel pipe from a new shower valve to the new faucet. All the other new pipe I used was the fancy black-coated kind. Before sealing all the pipe into the wall I made sure there were no leaks (I could find). I did notice a small amount of brown sedimentation when I turned the water on, but I figured this was due to air in the pipes. I then finished the wall, and began to use the bath.
I immediately noticed that brown water came out of the faucet when I turned on the cold water, and that it contained rust particles. I figured this was due to the new galvanized steel pipe or the new shower valve, and that it should go away over time.
Well, now it's been three months and the rust is still coming out and staining my tub. The rust only comes out for a second or two, but there is enough there to stain the tub orange. I am wondering if I did something wrong with the pipes, of the rust will ever go away, or if there is air somehow getting into the pipe... although there are no leaks noticeable downstairs...
Thanks!
