Orange staining in remodeled bathroom
We added a bathroom in 2009 to our 1940s Cape Cod. Since then I have been fighting orange staining on the shower tile grout, the shower pan, the toilet bowl, and around the silicone in the drain in the sink and shower pan. This does not happen in either our powder room (which has the original fixtures) or our second floor bath. We added a kitchen addition at the same time, but those surfaces are stainless steel so it is hard to tell if the same thing is happening. When we change our water filter, it is a reddish orange color also. Pex was used in the new addition and also replaced the pipes to the second story bath. Anybody have any experience with this?
