Water heater bypass valve

[Yoda]

In blowing things out, I found that there was water trapped between the water heater isolation valve and the water heater. The line drops between the nautilus panel and the water heater that is located on the opposite side of the trailer. If you not bowing the line out, be sure to run antifreeze through it. I just cracked the valve while plowing things out.

Also the last step I take after putting antifreeze in the lines it to open all faucets and then open the low point drain. I also operate the toilet valve. Doing this siphons a lot of water/antifreeze back out of the system.

Hope this helps

Don't forget to crack open the low point drains after the system is full of antifreeze. (Ask me how I know this ) BTW, replacing the low point drain caps with small valves simplifies this.

OK, I'll ask "how do you know"? Wouldn't opening the low drain points allow the antifreeze to run out of the system? Or are you saying crack open and then close?
