  • Easy Question...

    If I have a boiler drain, and I want to blow air through the lines, what adapters would I need to convert it to the size of an air compressor?

    Thanks guys.

    What size is the drain piping?
    Is the compressor hose 3/8 IPS or the larger commercial twist-lock style?

      It's not DWV, it's water lines that I want to blow air through before it starts getting too cold.

      And it's the 3/8" style/size.

        Make up some adapters to fit the water lines (boiler drain lines) then get a 1/2" IPS nipple and a 1/2" X 3/8" reducing coupling and screw the air tool connector into the 3/8" end (get the one that fits your air hose...)...
        Connect 1/2" nipple to the system you want to blow out and connect the other end to your compressor and let'er rip...
        If you want, put a threaded ball valve into the adapter to give you the on/off function where you are working instead of having to connect and disconnect the line to control flow...
        The boiler drain is probably an IPS size - you can make that connection however you want adapting from 1/2" IPS to the given size...

          Aaron, be really careful using air.

          As a certified low pressure boiler inspector and past unfired pressure vessel inspector I have seen the dangers that "air" can do.

          Many years go I was sent to Oklahoma as part of an fact finding team to find out why a water heater exploded killing several children and knocking out a school building wall.

          If you want more information why not to use air just let me know.

          If possible open a faucet place a wet dry vacuum on the lowest connection and go around pulling water out rather then air pressure.

          If you decide to use air keep the pressure as low as possible

            Don't leave us in suspense, do tell us the "dangers of using air".

                        He's talking about a "blow-off" line which is drainage. Why didn't you direct him to your website, which includes informative articles on nothing.Although I have to admit I have never seen a plumbing discussion board with an entire forum on S-10 pickups. You sir may be ahead of your time. But in the mean time, you're good for laughs.

                            If you were sent there then you would have known that the plumber didn't use air in the system. He put a plug in a leaking Pressure Relief Valve....duhhhhhhhh

                              Like all things like this there was more than one issue which lead to this accident. However, as you have already pointed out the one thing the tech did not do was induce compressed air into the line.
