摘要： In a method and apparatus for detecting leaks in riser and lid assemblies, a difference in pressure between the inside of the riser and cover assembly and the outside is created and monitored to insure that no leaks exist. Preferably, a vacuum is created on the inside of the riser and cover assembly. This vacuum is then monitored for a set period of time to insure that the total change in pressure does not exceed a threshold. In a highly preferred embodiment, an apparatus automatically creates the desired vacuum and then isolates a vacuum gauge to monitor the vacuum in the riser. Method for isolating a leak are also presented in the event that a leak is detected.
