 Relocating a central vacuum pipe
Author: mbmsv (Non-US)

Hello experts,

Sorry, this is not a plumbing question but I couldn't find a better place to ask it. After all pipes are pipes :)

I am doing renovation and need to relocate a central vacuum pipe, which happens to be 1.75" OD old Kenmore pipe. So, what is the best way to approach this:

1. Buy a bunch of 1.75" to 2" adapters and run 2" pipes where needed?
2. Replace the whole thing with 2" pipe? If I go this way I will probably have to replace the outlets and the hose too, right?
3. Get rid of the central vacuum altogether?

Your help is highly appreciated.

I'd get the adapters.

The adapters will create rough spots where debris will collect. Some "central vacuum stores" still have the 1 3/4" pipe and fittings.
