do what dubldare said
try doing what that fellow told you to do....
its ease and can take care of the problem without too much
grief
AI dont know what the "nodes " are that Hi mentioned, but have
had fairly good luck with this next approach...
the next approach is to turn off the water to the heater, turn the
gas to piolit
relieve the pressure then take the drain valve totally out of the unit..
The water willl come out of the hole and make a mess,
make yourself a "mineral scraper" out of a piece of 3/8 copper
about 30 inches long
flatten down one end about 2 inches worth then bend it and make
an L
...Reach into the hole and simply scrape the bottom of the tank with your
new psecial tool........
It will even get to those hard to reach spots on the back side of the chimmney.....
as the water is comming out , so will the deposits.....
of course its going to make a hell of a mess on the floor
but a guy has got to do what you got to do
and I hope its
in an unfinished area of your basement--garage
It will silence those demons, for a while...maybe 1 year..
then do it again...
