Draining water heater through low point drain
On my last trailer I was able to drain the water heater through the low point drain by holding the relief valve open. I like to do this just because it's easier and doesn't require tools. I tried it on our new trailer and it doesn't seem possible. I hear a slight amount of air from the valve but absolutely no water comes out of the low point drain. I confirmed it by pulling the plug and it was still full. We camp in some places with questionable water so I like to drain in between trips. Am I missing something or is this trailer plumbed different? I don't need to check my anode rod every 2 weeks!
