[C320-list] Water System 1996 #361

[Colin Evans]

For what it`s worth.  I drain the tanks by taking the whale connections
apart at the isolation valves under the sink, and let the water run into the
bilge which I pump out manually. The auto bilge pump only pumps out about a
litre then the float cuts the thing out.  It also proves that the manual
bilge pump is clear and working.  Something we don`t use too often ( I hope)

The thought of having the water pressure pump pumping out 160  litres is not
appealing.
I wipe around the inside of the tanks with a cloth soaked in bleach and
rinse twice .

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

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.
