I have properly painted and well maintained 200 Gal steel water
tanks. I have opened inspection ports and gotten well into the tanks
and scrubbed with Chlorox and washed and rinsed but still get the
sulfur/rotten egg smell after a short time. Suggestions??? What am I
doing wrong or not doing.
Unless the totten egg smell is ONLY in the hot water, I suspect you just
need to recommission the system, which should be done at least annually
as PREVENTIVE maintenance:
Although most people think only in terms of the tank, the plumbing is
actually the source of most foul water, because the molds, mildew, fungi
and bacteria which cause it thrive in damp dark places, not under water.
There are all kinds of products sold that claim to keep onboard water
fresh, but all thats really necessary is an annual or in especially
warm climates, semi-annual recommissioning of the entire systemtank and
plumbing. The following recommendations conform to section 10.8 in the
A-1 192 code covering electrical, plumbing, and heating of recreational
vehicles. The solution is approved and recommended by competent health
officials. It may be used in a new system a used one that has not been
used for a period of time, or one that may have been contaminated.
Before beginning, turn off hot water heater at the breaker; do not turn
it on again until the entire recommissioning is complete. Icemakers
should be left running to allow cleaning out of the water feed line;
however the first two buckets of icethe bucket generated during
recommissioning and the first bucketful afterward--should be
discardedbleach does absolutely nothing to improve the flavor of good
Scotch!
Prepare a chlorine solution using one gallon of water and 1/4 cup (2
oz or 25 ml) Clorox or Purex household bleach (5% sodium Hypochlorite
solution ). With tank empty, pour chlorine solution into tank. Use one
gallon of solution for each 5 gallons of tank capacity. (Those are the
official directions. They work out to 1 quart or litre of bleach/50
gallons of water , which is MUCH easier to calculate!)
Complete filling of tank with fresh water. Open each faucet and drain
cock until air has been released and the entire system is filled. Do
not turn off the pump; it must remain on to keep the system pressurized
and the solution in the lines
Allow to stand for at least three hours, but no longer than 24 hours.
4 Drain through every faucet on the boat (and if you haven't done this
in a while, it's a good idea to remove any diffusion screens from the
faucets, because what's likely to come out will clog them). Fill the
tank again with fresh water only, drain again through every faucet on
the boat.
To remove excess chlorine taste or odor which might remain, prepare a
solution of one quart white vinegar to five gallons water and allow this
solution to agitate in tank for several days by vessel motion.
Drain tank again through every faucet, and flush the lines again by
filing the tank 1/4-1/2 full and again flushing with potable water.

The Moore Haven lock re-opened on Sept. 23 after extensive maintenance.
The entire OWW is now open and has a minimum navigational depth of 8.48
feet. A neighbor, who had to leave his boat on the lake after returning
from the Bahamas, brought his boat home to Ortona a couple of days ago, and
reported everything back to normal. Hope to see some of you Trawlers and
Trawlering folks coming through the canal again, soon. We often have a dock
available for short-term visits, for up to 45' and 5' draft. We're located
one mile east of the Ortona Locks, about 10 miles east of Labele, FL.
