? for Tim .Condensate in gas line/or sabotage

Many times when a gas line

comes from underground then into a warm building and then back out again it will form condensate. Sometimes it has even been known to freeze right at the point were it reaches the top of the roof. We used to put a 18" long drip leg on some of these and pour "methanol" into the 18" pipe this would dry out the gas as it left the building. With the extreme cold temperatures we have been having I am not surprised at what you found.

Once you get all the condensate

out I would hook up a drip leg and put some "methanol" in the drip leg to absorb any moisture that is left over.

Drip Legs/Making stuff up:

I don't make this stuff up.

If you have a drip leg outside, like you explained, it is a very good idea to have a valve above the drip leg ( in the situation as you describe) with a 12" nipple, filled partially with anti-freeze. So that the condensed water vapor can mix. You or someone needs to check during cold weather for the drip leg filling with water. You need the anti-freeze because if it is straight water, it can freeze and break. And you know what happens then.

Air filled automatic fire sprinkler systems can get large amounts of moisture in them if the air compressor runs to fill air leaks. If a low point isn't drained of water, the drip may blow off and set the water running. Never a good thing and the Insurance companies don't like to pay unless you can show that someone was regularly checking the low points. I had a large commercial account that used to put special winter drips in place and a maintenance person went around once a week and drained every drip. The ones closest to the compressor had the most water.

According to the gas companies, there's no moisture in their gas.

Really?

Really.

And the Nat. Gas companies weren't injecting air and LPG into their lines to keep the pressures and BTU's up and it had nothing to do with the huge rise in Propane prices last winter. Not a darn thing to do with it. All "market forces".

PROBLEMS ARE NOT DUE TO LACK OF SUPPLY BUT OLD PIPING

In my neighborhood, they replaced the 60 year old iron (or steel) piping that had a nominal 15 PSI pressure (actually closer to 8 PSI if I remember correctly) that looked about 3" to 4" diameter with plastic piping at least an inch bigger in diameter and had 50 PSI in it. On my short street (a dead end one short block long) they had already removed the iron pipe and replaced it with about 2 1/2-inch plastic pipe, and to my house was 1-inch plastic just up to where the pipe came out of the ground, where it was steel. That went into a pressure regulator and into the meter. After the meter it is 1-inch black pipe, 1-inch CSST (damn) and then back to black pipe down to the boiler.



Many many people on my street are running gas boilers now.



They did the changeover both because the demand went way up since just after WW-II, but also because they were spending a fortune digging up the streets every few weeks to fix leaks. I think that it was probably cheaper to replace all that old pipe than to come out all the time to fix leaks.
