The first time, I thought maybe it was contaminated fuel or perhaps there was the remote chance that I had left the line open long enough for condensation to form. My friend, who co-owns an LP company (he was in charge of installations and repairs. decades of experience) purged the line and commented that "this is weird, I've not seen this much condensation before." Anyway, I put it on the vigilance list. The lines haven't been left open except for a minute while changing tanks and even then I close the ball valve so that just the dual tank manifold is open.
Two years later, I have enough water in the line that during the past deep freezes the line is plugged by ice. When we get a thaw, like today, I can relight the gas logs. Having spent the last hour or so purging the line with an air compressor to get ready for tomorrow's snowstorm, I'm asking gmcnet if anyone else has had similar experience?
Here's my setup:
2 x 40# aluminum tanks on a manual switch-over manifold with a hi-pressure regulator. The 3/8" OD copper line is exposed for 8 feet before it enters a 4" chase pipe. It then travels 75 feet, loops up next to the foundation where a low-pressure regulator is installed, then goes back underground 25 feet before surfacing in the crawl space under the gas logs.
