Bought a new home a year ago with a 10 year old upright electric hot
water tank and the hot water gradually started to turn the yellowish
brown sort of color, so read up on solutions and 'flushing' seemed the
approriate action

First flush and suspicions confirmed as brown (along red) dirt sediment
started to rush out, flushed from the top with a garden hose and
through the bottom via the cold water inlet valve till it ran clear
again

Remained clear for 24 hours before it started to go yellow/brown again

Same process as above, lots more brown/red dirt muck sediment came out,
flushed top and bottom till clear, water clear for 24 hours then next
day dirty yellow again

And so this process has gone on for a month now with 2 full flush
cleanouts a week, but still the hot water remains a yellow brown (cold
water is fine and cold water via the inlet valve is also fine) and am
getting might annoyed by now!

Probably flushed out a good few inches of fine dirt - not overly
impressed with my water provider either and previous house owner

Is a ceramic/glass tank

I have a suspect that the sediment is lining the sides of the tank but
can't get at them with the hose through the top hole????

Is there any suggestion to what I can do to give it a complete flush to
cleanout the crap out once and for all or need to seek professional help

I have found that the drains supplied on water heaters are fairly
restrictive. Next time you drain the tank. Remove the drain valve. Mine
have been standard 1/2 pipe thread. Get a nipple and hose adaptor and
screw in to replace. Run the hose out side some where and turn the water
back on. I always get more sludge and crud doing this. If this does not
have a positive effect then it is time for a new water heater. Considering
the dirt you are getting I would be putting a paper particulate filter on
the supply for the whole house. You will be amazed when you change the
filter in 6 months.
