I lost one compressor to a bad drain valve that I could not close after a few year and that I could not get out at all.

I like the new Craftsman compressor I got but the drain valve started acting up as well, not sealing well when closed, so after the warranty was over I decided to change it and make it easier to drain the compressor.

Step 1 is to remove the drain valve… some red thread locker was used. I had no problem removing it but you might want to use a torch to ease it up. Then clean up the threads a little.

Here are the parts I used (I simply went to HomeDepot for them – you might need different lengths of pipe for your compressor):

Start putting things together. I used thread sealer for the connections.

I also used a hose so I direct the drain water to a small pan, instead of having it go on the floor and discoloring it.

And here is the drain valve I removed.
