It's possible that your H/W tank needs to be cleaned out. If you haven't done this in the past 5 years, then it's almost a certainty.

You first turn OFF the power to tank, then attach a hose pipe to the bottom fitting, lead it outside or to any drain, turn on the valve by it, turn OFF your inlet valve and open the relief valve so air can enter the H/W tank.Let the whole tank empty -takes about 30 -40 minutes. Next, when empty turn ON the inlet valve and let cold water run through the tank and out the hose, now you will see the sludge coming out. Let this run 5-7 minutes or until water is coming through clean. Now you are done . Let it fill, then turn on power.

It doesn't. Methane is odorless. Natural gas has ethyl mercaptan, a strong smelling gas, added to it so we know if there is a gas leak.

Methane itself is odorless. The natural gas that we use for fuel has ethyl mercatpan added to it to give it a noticeable smell.

Is methane odorless?

Actually, no. Methane itself does not have an especially pungent odor, making it nearly impossible to detect leaks via sense of smell alone. Thus, a foul-smelling compound is added to methane before it's used commercially, for safety reasons. The smell most people associate with methane is actually that of methyl mercaptan (methanethiol), a sulfur-containing compound.
