Posting for a friend, so I don't know all the details.
The problem is the natural gas water heater is producing dirty hot
water most of the day (a few days now). The thing is the heater was
fine until after a gas related repair was made. Actually, I believe
all that was done was the gas was shut off for a few minutes (the
water heater pilot had to be relit), so I don't know how that could
have caused the dirty water problem. The heater now also makes a
strange popping/gurgling sound when it is heating.
Does anyone know what could've happened? Thanks in advance.
The burner may be getting a better gas feed with more pressure and is
boiling the water causing all the deposits to mix with the water.
Have the gas pressure to the burner checked and make sure it is not over
fired. An over fired burner could damage the tank.
In time the debris should clear up. Darrell

The water heater is asking to be drained of sediment. Read the instructions on
the unit for the proceedure and the problem will surely clear up in a few
hours. Good luck.
you have a buildup of sediment and or hard water deposits in the bottom
of the tank, turn off the water heater let it cool, hook up a hose to
the drain valve run it to a drain, open valve and flush out tank, a tank
should be flushed out yearly, some old valves can get corroded shut or
leak, know where your water shutoff is incase you develop a leak at the
valve and have to repair it
With the heater now working as it should, it sounds as if you now have
the thing burning hotter as it should and hard water scale has trapped
water under it which turns to steam which sounds like explosions; which
it is. This is not good for the tank and will eventually cause it to
leak. Scale is not good for a water heater and increases the fuel costs
substantially; especially with oil and gas fired heaters. A softener
might be a good solution.

Thank you all very much. We're definitely going to drain/flush the
Please forgive my ignorance, how do we set the gas pressure to not
over fire the burner? I'm curious as to why the burner is getting a
better gas feed now. I'm not sure if the temp setting on the water
heater was changed--I believe it's set at 140.
Something else I forgot to mention is that the water pressure is a bit
lower now too, does this relate to everything that has been suggested?
some sediment is probably cloging your faucet screens, lower your water
heater thermostat 20 and see that the temp stays even, a bad thermostat
could raise the temp to much causing the pressure release to leak
