Blackish rust debris coming out of bath faucets
We have a black/rust looking debris coming out of the tub faucet in one bathroom and through the shower head in another. My H told me tonight he has been taking the shower head off twice a week and cleaning the debris out so we can get a good flow. The bathtub always has black flakey looking particles in the tub. I can't rinse it out because more keeps coming when the water is turned on. What could be causing this? We have copper pipes. I am so worried that our pipes are deteriorated, we built this house 34 years ago and just finished a major renovation. I can't bear to think of tearing out brand new tile bathroom and shower to repair this. Please help me figure this one out. Thanks in advance!!!
