[C320-list] Water System 1996 #361

[Tim Fleming]

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.
