Air Water Syringe - Sticky Buttons - Dental Equipment 

Hopefully it goes well. Let me know if you need another view or issue with it that needs solving.

@@DentalThings it worked! Thanks for the video !

@@DentalThings are you RDA?

@@XxAlex530xX I am an RDA.

@@DentalThings cool. I’m one as well. Dr is out of town so I’m just tinkering with stuff 😂

If the spring is put back in place then that' should bounce up and down. Maybe the button is full of junk under the piston that it needs to be taken apart to clean.
