A modified Lockable Well Plugs to produce the Waterra Vapour Sampling Well Plugs. This specialized well plug uses a valve which allows you to extract a sample of the trapped headspace vapours.
Pressure tested to 20 PSI, these well plugs prevent the loss of well gas to the atmosphere. The Sample Port Adapter allows you to extract the sample without removing the plug from the well. The Sample Port Adapter can be attached to a peristaltic pump in order to draw out even more of the trapped headspace gas.
