Smell from new indirect water heater

in Domestic Hot Water
I just had a crown mega-stor ms-40 installed with a buderus oil boiler and have a smell coming from the hot water only. Initially there was brown water and that cleared after running the water for a while but the smell continues after multiple showers. Could it possibly be a bacteria even though it is brand new? Should I call my installer or give it some time to clear? Thanks.

    Bacteria

    We can't tell you what to do, did you get the tank inspect, if you think you have bacteria in your water I would call the health inspector.



    Why would you even wait on something like this?

    Inspection

    Do I have to have the tank and oil burner inspected after installation? All I am concerned about is the smell, I don't know if this is normal with a new tank.

    Anode

    Is there an anode in the crown mega-stor ms-40? I can't imagine this is causing the smell as it is only 2 days old.

    Stinky smells:

    If it is only the hot side and it smells like rotten eggs, it is hydrogen sulphide, it is from the magnesium anode rod/sacrificial zinc. It will go away with time.

    Do you have a well? If you do, draw a glass of COLD water from as close to the source as close to the source, before the tank as you can. Once the glass is full, sniff it. You can only sniff it ONCE. There's no second chance. You have to draw another glass. If you smell "rotten eggs", you have iron bacteria. It can be fixed.

    that is a stainless tank

    no andode rods, according to the online installation manual.



    What type of smell? Sometimes the pipe dope used for the installation has a smell, Rectorseal #5 for sure :)i



    You can set that as high as 150F, maybe run it hot for a day if you suspect bacteria.



    Does it have a thermostatic mix valve? If not be very careful when running elevated temperatures in the tank.

    Smell

    It is day #4 after install and the smell has either gone away or we are used to it. Hot Rod, you may be right that it was due to the pipe dope and hopefully are. Thanks for letting me know about the anode rods, but why does it not need them and is that a good thing?
