Absolutely, and not just one floor but 3 or more. To do this you need a strong vacuum system of 20’’ to 25’’ Hg. Here is how it works. A high vacuum energy system is a low flow system. Low flow means that air and water can move slow in large diameter pipes so you want one piping system of not more than 2’’ diameter if you want to pull water upstairs.

In our lab we set up a tortuous vertical piping system and we installed a droopy clear flex hose as the bottom 90° inlet connection. The water filled the horizontal manifold as we used dental suction tools in buckets of water. We could watch the water slide up and down the flex hose elbow. As the hose filled, the velocity of the air increased (more liquid, less air space) When the water filled 75 to 80% of the hose diameter suddenly the entire liquid quantity shot up the vertical pipe.

What happened was the water in the vertical pipe sealed the entire diameter. The strong suction pulled the water up acting as a piston sucking all the water up behind it. This piston action means no loss of suction at the dental suction tools because the atmospheric pressure rushes through the tools to fill the space left as the water roared up the pipe.

Simple and it works but you need a strong pumping system. BaseVac Dental Vacuum Systems are the only systems with up to 25’’ Hg suction energy.

Please remember on any vertical wet collection piping system check valves must be used at the bottom of each vertical drop to ensure water will never flow backwards if the vacuum system is shut off. I also recommend a 12’’ drop leg below the tee connection and check valve with a manual drain. This ensures a waste trap and pipe clean out needed on vertical pipe systems.
