Free Flow Pipe and Hose Maintenance Sheets

Product Details

Free Flow Central Vacuum Maintenance Sheets are the homeowner's choice for central vacuum system care, no matter the make, model or year! Simply vacuum a sheet or two directly through the hose at each vacuum wall inlet. Each container contains 25 sheets which travel through the hose and pipes and stay in the main unit. Everything is cleaner, air is flowing faster, and the system smells fresh!

Benefits of Using Free Flow Sheets
Your central vacuum system is a major built-in appliance with long pipe runs that would be very difficult to replace if damaged. It is essential to take care of them even if they have never been serviced. The average home has over 1000 feet of pipe throughout the walls, attic, basement, and soffits. Free Flow is the quick and powerful way to keep your system clean and maintained.

What Do Free Flow Sheets Actually Do?
When suctioned through the hose end according to the directions, Free Flow Sheets clear the inside of the hose and pipes as they travel to the vacuum unit. Their volume and speed force larger objects such as pens, batteries, match box cars, rocks, hair-fuzz balls, jewelry, and sticks to the main vacuum unit. Free Flow Sheets are the perfect balance of density and moisture. As they travel they are also wiping the surfaces. The powerfully pleasant scent leaves the entire system smelling clean and fresh including the exhaust of the main unit because the sheets simply remains there.

Do they ever clog your pipes?
If your system is developing a tough clog, this product should push it all through, but there is a chance it could get stopped up even more. However, that may not be a bad thing as sometimes clogging the pipe can help the vacuum build pressure to force the difficult mess through. If it can't push it through then the clog was bound to be a problem anyhow, yet we have methods in our trouble shooting guide for resolving it.

Product Change
First quarter 2015 the product was changed from Tornado Power Maintenance Cloths to Free Flow Maintenance Sheets. They are essentially the same product.

I like these but they are VERY difficult to feed out. they wouldn't pull up from the inside of the coil and there's no access from the outside of the drum either. I have used them a couple times already and they do improve the scent in the hide a hose ports.

I use this abrasive material cloth to clean all dust or damp dirt build-up that within my vacuum flex hose and rigid pipes. I believe it helps to prevent build up clogs.I use it approximately monthly.

This is a great way to clean vacuum lines and get rid of musty smells coming out of the vacuum exhaust. Also seemed to improve the amount of suction my vacuum has.

Wish I'd known about these when we first moved in...cleaned out the extra lint/fur in the line and left a pleasant scent behind. Will definitely be using these on a regular basis.
