Tolivac, that's awesome, I can't wait to hear what you think of it, I think you will love it since you're like me and like to use central vac units free standing. Unless yours is set up differently it should come with a utility valve already screwed in to the in-let, you can easily remove it though if you want to connect to pipes. You can use the hose and tools that come with it or another hose, it sounds like you already have plenty of central vacuum accessories. Wait until you see how portable it is, it has a nice carrying handle on top, the bags are not as large as other central vacuum units but this vac was designed to be portable. You could mount it on a cart but there's really no need, it's so easy to carry, just put it in a convenient place and connect a central vacuum hose, again, can't wait to hear what you think of it. When I first got it, I thought it was not going to be as powerful as other central vacuums since it's much smaller, but I was pleasantly surprised, when using pipes, it can handle a home up to 8000 square feet. I honestly cannot think of a single thing I don't like about it.
