Hi Rbacableissue,
Welcome to our community and thanks for posting. Sorry to hear that you're having difficulty installing your new equipment with us. We know how frustrating this can be especially if you don't have the correct fittings.
As our valued member @Tudor has advised if you could post some pictures of what you have in the property that would be a great help. If you can't don't worry.
You can follow the link here, we also have a YouTube video here.
If you need any further assistance, please come back to us.
Kind regards Jodi.
