It shouldn’t be a surprise that your tap water should be colorless when it comes out of the faucet. It can look hazy sometimes as a result of high pressure but should become colorless once more when the pressure evens out. If you’re noticing that the water is coming out brownish, rusty, or has small, dark particles in it, the water heater may be at fault. This can be the result of sedimentation, which will change the color to brownish, and lead to serious health concerns for your family. Having your tank cleaned out will usually correct this issue. However, if sedimentation isn’t the problem, your tank may be rusting, which can necessitate a replacement.
