Hi everyone. I have a Baxi HT330 and I need to disconnect and replace the copper elbow connected to the valve with the blue handle in the picture I'm uploading. Because of work I'm doing I cant reuse the elbow and need to connect a straight piece of copper tubing to the valve. Does anyone know if I can use a simple 3\4" copper union or a female copper fitting to connect to the valve or do I need a special size fitting with a washer? I know this is probably a basic question but I would like to know for sure before I try to use the wrong fitting and screw up the threads on the valve. Thanks for the help. Scott![]()
