Leaking water heater on 22FB
Howdy folks, so I've noticed over the past couple of weeks that my water heater is seeping a bit of water out of the top spigot and soaking up the wooden base (picture included shows where you can see a trail of white running down the heater and if you look closely you'll see the camera flash reflecting off the top spigot leak). I haven't taken a wrench to the top connector primarily because it's plastic (duh!) but I have tried to tighten it by hand and it seems very secure.
I seem to recall reading on a website somewhere that 'purging' the system every so often is necessary because of an air bubble. Is this true? I've owned the trailer since July '11 and live in it full time so the heater gets a decent amount of use.
