Handle for Low Voltage On-Off Hose Q&A

My Vacuflow is 7 yrs old. The hose ripped and became disconnected right at the place where it connects to the Turbogrip. Do I have to replace the entire hose and/or Turbogrip? Can this be repaired and if so, by whom? I live in Seattle, Washington. Thanks.

Will this handle replace the Turbogrip that is connected to the hose which plus into the Vacuflo low voltage central vacuum system I have in my home?

Today, I dropped the handle and the inner ring connecting the handle to the connecter for the attachments broke. (It looks like your picture only in two peices now) What is the replacement part(s) I need?

I have the old style handle. The rocker switch is broke and I can't turn the hose off. Can I purchase the switch assembly?

My handle looks like the picture but how can I tell if I also have the old style? It was purchased in 2000. It came with the Air Master vacuum system.

I'm replacing my cracked hose handle with your product. What is the trick for assembling - is it necessary to unsolder the wires and remove the front assembly to get the back ring (the one shown in the centre of the above picture)onto the hose? Or do you expand the back ring with hot water to slip it over the assembly without taking the wires off? Thanks
