: We have all copper plumbing but we still get occasional slugs of rusty water that is particularly noticed in our clothes washer. We have discussed the problem with the water company and they have not been able to help except to give us some rust remover to use. Could our Rheem water heater be the problem? It is about 16 years old.
I see alot of galvanized nipples on the inlet and outlet of water heaters. This is the first place I would check.
However, your water heater has also lived beyond its normal life expectancy. You may want to consider replacement.
