[C320-list] Water System 1996 #361

Tue Apr 23 18:16:47 PDT 2013

Following are 2 different strategies from my archives.  A third method is on
page 29 of the C320 Owner’s Manual.  Pick your poison

1.            Shock Treatment – Add 8 ounces bleach to every 10 gallons of
water.  Open all faucets and keep them open until water exiting smells like
bleach.  Turn faucets off but leave pump on and the system pressurized.
Leave for 8-24 hours then flush tanks at least twice.  Drinking Water – ½
teaspoon of bleach for every 5 gallons of water.

2.            (From Jon Vez)  The product is Puriclean. It is non-toxic and
biodegradable. It comes in powder form in the freshwater kit. You simply
dissolve the specified amount in a cup of hot water and pour into your
tanks, fill them and wait 1-12 hours. I do this once in the spring and if I
haven't used my water in a while, will put a teaspoon in once or twice
during the season. Many places sell it and I'm sure there are competing
products, but I've attached a link so you can see the product....

Thanks! 

Ok will go with 3/4 cup bleach in gallon of water in each fill each with
water, open both valves and then run till I smell bleach/chlorine, then fill
whatever I drained.  Over nite wait, drain, fill, drain,  fill... Done.   I
leave forward one empty unless long cruise so will drain that. Sound ok?

Tim, 

Basically, 3 days ago, I pumped out any/all antifreeze I could get out, put
a couple of gallons of water into each tank, then pumped that out, repeating
that step twice to clear out as much antifreeze as I could. I then took a
bucket of water (about a gallon, and added about 3/4 cup of bleach to the
water, and poured that into the 2 tanks. I then filled both tanks with
water, pressurized the system, and left it overnight. I then pumped out each
tank, refilled with water, pumped out again. Another quick spray inside each
tank and a pumpout and I think the system is ready to go this year.

Thanks but both of these I find a bit vague and confusing. Anyone have
better, specific instructions to clean out our specific size Cat 320 (2)
water tanks? (Bleach to water ratio in a bucket?) Wonder if peroxide would
be better too .. Just wondering. 

Also if you run it to empty it could cause a vacuum prob air pocket and one
has to re-prime the pump some how (had that happen once blew water into into
it- yuck and unsafe I am sure). So again, anyone have better?

I always trust advice from the Head Mistress, Peggy Hall, although you may 

have difficulty measuring deciliters!

Basically similar procedures, a weak bleach solution to allow about 70 ppm 

sodium hypochlorite as a shock (Peggy's works out to 375 ppm). 

Pre-dilute it any way you want as long as you wind up with around 70 ppm in 

the tank (taking into account that the bleach is already usually a 5% 

solution). 

I'm told that cruisers like to take dry pool chlorine along for this task. 

I use this procedure every spring, allowing the treated tanks to sit 

overnight. I empty and refill and have found it unnecessary to flush the 

tanks as any residual chlorine has been diluted 100:1 and disappears 

quickly.
