Last year I winterized using the 1965 manual directions and all was fine. This year I decided to put RV antifreeze throughout the system and used a propylene glycol based pink antifreeze. I thought it was alchohol based and am worried about this stuff. Should I flush everything now and start over or can I flush the system in the spring? I do not drink the fresh water but use it to wash dishes. Also should i use a soap to flush the system or just fresh water?I would appreciate any suggestions. thank you
Well i feel better about having put the stuff in my potable water system.Think I'll go with the vodka next year although it will make a grown man cry to see it go down the drain. Thanks for all the suggestions..RiverRat
If it happens again, try leaving the heating element turned off and just run cold water through it until the odor is gone. Heating the antifreeze is probably what caused the smell to persist.
I never turned on the HW heater during this mishap. I spotted the problem when I ran water through the heater. Like I said, there wasn't really that much pink stuff in there as I spotted the open bypass before the tank filled. I was surprised about the time needed to flush all this out. In an older tent trailer I would add the pink stuff directly to the FW tank and pump it from there. I never had trouble flushing the system. The only difference I could come up with was the metal HW tank. I had the smell and foaming water out of the HW tap for at least a month. Lesson learned.
No, you don't have to worry about a lot of hydrogen gassing and plumbing damage...IF you follow what I say in my first post. I NEVER suggested putting Clorox in WITH the antifreeze. I said to sterilize the system with Clorox AFTER flushing well with clear water. If the flushing is done correctly and completely any minute AF left would be so dilute so as to be virtually non-existent. I addition, the Clorox is being diluted to a few cups in 63 gallons of water. I have used this process for 3 decades and never had any gassing, ill effects, nor any plumbing issues of any kind.
That being said....DON't mix Clorox with the high concentrations of AF in your lines proir to flushing well with clkear water.
dznf0g, we too have used the same one you have described for the past 30 or so years and never had a problem. This is also the process described in many RV manuals.
