Ok just like a few others on here. I have smelly water. Either when I turn on the cold or hot water but more so the cold. Since I changed out the hot water tank just a few weeks ago. I have refilled all the water traps and cleaned all drains. It has to be the cold water but other neighbors not complaining of the bad smell, maybe a bateria growing in plumbing. The smell isn't from the drains you can smell it in a cup faintly but when it's running through the faucet it's strong. Any one have any suggestions don't want to call a plumber. I have a water baffle plumbing system with the red and blue water lines. I love this system, great for maintenance. I appreciate any help Thanks JMaple

Are you on a pump or city water? Remove a aerator and see if the water still smells. You say this happened ONLY after you replaced the hot water heater? More details please. Tom

No the water was stinking before I replaced the hot water tank I replaced it due to old and anode was causing hot water to smell. I'm on city water, however other neighbors not complaining of smell. Thanks again

Does this affect all the faucets of just a few? Let me know, Tom

Seems to affect every faucet however I didn't smell it in the faucet we use once twice a week but the ones we use several times a day more so than others.

Also even the bathtub facet when run water strong smell think its because more water which equal more smell?
