Tanques agua dulce. Mantenimiento (En ingles)

[Miahpaih]

Alguna vez os he hablado de Peggy Hall y su magnifico libro de tratamiento de los
sistemas sanitarios a bordo. Considerada la Gurú de todo esto, es un libro que
todos deberíamos llevar a bordo.

Aquí os paso información de como ella recomienda el tratamiento prolongado del
agua fresca a bordo. Lamentablemente está en ingles y no me considero capaci-
tado para traducirlo, pero para los que mas o menos dominen el "jinglis", creo les
será de mucha utilidad. Los demás que se busquen un amig@ y a cambio de unas
se lo traduzca.

Here it is, just as Peggy said it.


Fresh water system recommissioning procedure, by Peggy Hall

Fresh water system problems--foul odor or taste--are typically caused by
allowing water to stagnate in the system. 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. Many peopleand even some
boat manufacturersbelieve that keeping the tanks empty reduce the
problem, but an empty water tank only provides another damp dark home
for those critters.

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 discarded.

1. Prepare a chlorine solution using one gallon of water and 1/4 cup (2
oz) 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. (Simpler way to
calculate: 1 quart bleach/50 gal water tank capacity)

2. 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

3. 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.

5. 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 vehicle motion.

6. Drain tank again through every faucet, and flush the lines again by
fill the tank 1/4-1/2 full and again flushing with potable water.

An annual or semi-annual recommissioning according to the above
directions is all that should be necessary to keep your water tasting
and smelling as good as anything that comes out of any faucet on land.
If you need to improve on that, install a water filter. Just remember
that a filter is not a substitute for system maintenance, and that
filters require regular inspection and cleaning or replacement.
