You managed to explain in words how an air compressor works (not just the pump mechanism) better than any animation I could find. Thank you.

[@nackbaxster1369]

Hats off to explaining that so concisely. In a world of bad DIY videos and explanations you did excellent.

[@BustedBeaters]

Appreciate that!

Awesome video! You saved me from having to buy an air compressor today! My check valve had a bunch of gunk in it, reinstalled, and works great now. Thank you!

[@BustedBeaters]

I was hoping this video would help someone! Glad you got it working again!

[@richg.2579]

Thanks my compressor is doing exactly that. I was getting ready to replace the valve. You just saved me a big hassle.

[@BustedBeaters]

Glad the video was able to help you out!

[@RickRose]

Mine appears to be leaking inside the on/off switch itself. I'll go ahead and examine the check valve however. Thanks for the great explanation.

[@BustedBeaters]

Good luck getting it fixed!

[@leomania]

Thanks a bunch for creating this video. You have a nearly identical compressor to mine, which had the same failure mode. I bought the absolute cheapest valve available on Amazon (under $20) and so far, so good. 🤞

[@BustedBeaters]

Your welcome! I was hoping it would be able to help someone out! I was so happy when I found out it wasn't going to be an expensive fix!

[@BustedBeaters]

Not a problem! It's a pretry easy fix. I was I'm the same situation as you. Didn't want to spend the money on a new one

[@user-wk3rx2rn1g]

I had this exact problem with my craftsman compressor just short of 39 years after purchase. replaced the valve and everything is back to normal. now to see how many more years I can get out of it.

[@BustedBeaters]

Nice work! I imagine you'll get many more years!

[@johnnelwhite]

I just purchased an old speedair 26 gallon for 60 bucks I think this may be the problem with it.

[@BustedBeaters]

I hope it is your issue. It's a quick and cheap fix!

[@johnnelwhite]

@@BustedBeaters nope put the new check valve on and it still leaking out air from the pressure switch. The unit was made in 99 and has a one peace manifold. I think I'm going to just put a newer pressure switch, regulator with pressure and safety relief valve on it.
