To prevent clogs and debris from blocking the hoses and lines of our central vacuuming system, I take 5 lb of uncooked rice
to the various vacuum ports and let the rice get sucked through the hoses. As the rice travels through the lines to the canister,
it cleans out debris, residue, and blockages. I've repeated this process every six months for the past three years, and there
has not been a blockage in our vacuuming system or a loss of suction in that time.
