Vacuum plumbing is more similar to gravity plumbing than most people realize.  The hot and cold water service lines are the same. The drainage lines in a vacuum system are under negative pressure that allows the lines to be much smaller in diameter and run vertically up through the walls and across the ceiling cavity towards a centralized collection tank system.  Vacuum plumbing eliminates design restrictions, doesn’t require a consistent drainage slope, and eliminates virtually all slab coring and trenching. These advantages translate to construction cost savings and potential water savings of 70%.

Medical facilities are ideal candidates for vacuum plumbing but want to know how it really works. Let’s cover some frequently asked questions.

How is the system configured?

Vacuum plumbing is a self-contained system of fixtures (toilets, sinks, showers, eye-wash, etc…) with overhead flexible piping under constant negative pressure.

How does water stay inside the system?

A vacuum pump maintains the constant negative pressure. Interface valves separate the vacuum pressure from normal pressure inside the building.

How loud is the vacuum toilet flush?

The MedSpace vacuum toilets have been engineered to simulate the sound of a typical Sloan valve flush.  The actual decibel rating of a vacuum toilet is less than a gravity toilet.

Where does the wastewater go?

Storage tanks hold waste and wastewater for discharge to sewage.  Typically the system is programmed to discharge the waste from collection tanks once they reach 50% capacity.  The drainage can be metered to accommodate smaller sewer lines in existing buildings. This can avoid expensive infrastructure upgrades when converting commercial space into medical space.

What is another advantage for medical facilities?

Negative pressure in the vacuum plumbing system means toilets are “no splash.” When the toilets are flushed whether manually or from a sensor, negative pressure pulls waste into the piping system with no air escaping to cause a splash. “No splash” toilets are more sanitary than gravity toilets.

Vacuum plumbing reduces construction costs, delivers significant water savings, and is even more sanitary than gravity plumbing systems. Let MedSpace Innovations show you how our prefabricated architectural walls with integrated vacuum piping can deliver savings. Contact Us.
