Plumbing services for exhibit events are standard for industries like homebuilders, RV, boat, and food shows, and include services such as compressed air, water, drainage, and natural gas.
Let’s start with compressed air. A service line is usually a 3/8” ID (inside diameter) line with pressure between 90 and 225 PSI (pounds per square inch). It can also be measured in Cubic feet per minute (CFM). Basically it states how much air flow the compressor pushes per minute. The higher the CFM or PSI, the stronger the airflow. Compressed air lines usually come standard with a 1/4” quick coupler. Exhibitors are usually required to bring their own regulator, though some facilities have them available for rent. If you need this type of service then this would all make sense to you, so let’s move on to water.
Most purposes for water are for self-contained displays that have a water reservoir tank that needs to be filled to get the exhibit started. Think of a shower head demonstration that would recycle water through a drain and pump to move it constantly through the shower head ─ you see this quite frequently at a homebuilders show. Water is charged per unit to fill these tanks, waterbeds, or pools, and ranges between 100 and 500 gallons per unit. If you need a constant water supply for a food show demonstration, then you would pay for the water hook-up and the drain service. This can be for a hot or cold hook-up, or both. You can even rent the sink, if needed. Connection sizes are usually 1/2” or 3/4” pipe connections. Drainage connections are usually just a one-time fee to make the connection.
Next is a natural gas connection. Exhibitors are not allowed to bring gas cylinders into a trade show, so they would be required to order a natural gas connection from the facility. Service connections can be anywhere from 1,000 BTUs to 50,000 BTUs, with an average of 5 oz. of pressure available. The cost for each hookup includes the gas used. The exhibitor is usually required to provide the shut-off valve that would be part of the unit being hooked up.
General recommendations for plumbing services for exhibit events state that if air, water, and natural gas pressure are critical, exhibitors should make arrangements to have a pressure regulator valve installed. Facilities do not guarantee minimum and maximum pressure. It is also usually suggested that exhibitors provide a filter-separator for all equipment requiring air connections. The facility is not responsible for moisture or water in air lines.
