[C320-list] Water System 1996 #361

[dprudden at comcast.net]

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?

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.
