    Using 7cfm vac pump

    I have an under ground gas line that was run about 4 weeks ago. Water had gotten inside when customer removed protective cap. We have used nitrogen to remove most of the water, but since there are a few dips and pitches in the line, I still have blockage. I guess My Q: is "will a vacuume pump aid in the removal of the remaining water and at what rate? Any other thoughts welcome.
    Thanks Mike T.

    Two Quick Questions

    What size is the line and how long is the run?

    Sorry about that Eugene

    Line is 1" "Gas Tight" aprox. 60 to 80 ft. I know for a fact that when I blew it out, the line was clear per/say. But, due to the dips, the water layed in there not allowing gas flow. I think it's comming thru, but when the dip has water in it, the pressure is not enough to allow flow to break thru. Aslo, additional 1" hard drawn after that for about 30ft. I think the main water blockage is in the underground like though.

    Just a

    suggestion...that gastite is alot like flex duct it really create higher static and reduce flow.

    Without knowing the btu load on that line I would say your
    distribution is undersize if its low pressure.

    I just did one recently at 40 feet 150000 btu and it call for a 1 1/4 line with sealtite.

    Not saying thats your problem but I was just surpise at how big the gas line had to be for such a short distance.
