I have a Bernard mechanical releaser and was wondering are the little needle? valve that adjusts the speed of the vacuum shutoff to dump sap required on the releaser or can I eliminate it and use with out? reason for asking is I was replacing the small lines due to them being old and breaking on me several times last season and ended up on breaking a part to pull out the line out of that little needle valve so now its not usable anymore. not sure if I have to hurry up and get one ordered or if I can just run the new line without the needle valve. Thanks in advance!
