Don’t worry, it’s not just you! At LEVEL5 Tools, we hear this issue a lot when drywall finishers are getting started out with automatic tapers. You go to fill your taper and BAM, drywall mud starts and continues to ooze out of your gooseneck and all over the floor rather than going into the tube as it should.  '
Here are three common problems and easy fixes to get back to taping in no time...

Why Mud is Leaking from Your Gooseneck

1. The gooseneck is not fully inserted into the taper’s filler valve. This is particularly common when the valve or gooseneck is dirty or is need of some lubrication.

    Pro tip: Do not use silicone or spray lubricants like WD-40 when lubricating your automatic taping tools. Instead, use a light 3-in-1 machine oil.

2. The gate valve is open meaning that the taper is set to “tape mode” and not “fill-mode”. Close the gate valve by depressing the round disc on the dog drive clutch

     Pro tip: You can test that it is closed by turning the dog drive key, if you have properly engaged the clutch, the top wheel will not turn.

3. There might be blockages in your filler valve due to improper cleaning or maintenance. We get it! Cleaning your taper at the end of a hard day’s work is not always the most appealing thing to do but it is immensely important when it comes down to ensuring smooth tool operation and therefore consistent, quality finishes. 

If you have gone through all of these potential causes of mud spilling out from your gooseneck and not entering your taper, you should be up and running in no time.
