Step 5: Placing the pipe coupling
Take the clear PVC pipe and slip one of the 4" diameter pipe coupling (McMaster-Carr) on one end of the pipe. The open end of the clear PVC pipe will allow, the entrance of the data collecting device which will be connected to the probes that was inserted through the LTCF. After one coupling is situated firmly around the clear PVC pipe,
take a hose clamp and slip the clamp around on the coupling that is already situated around the clear PVC pipe. There should be a grove imprinted on the coupling that will allow the proper fitting of the clamp. Make sure that the clamp is nested around this grove and is aligned to the perimeter of the acrylic disc located inside the pipe coupling.
Then take a flat-head screw driver and begin to tighten the clamp until the coupling is situated properly (REMEMBER TWIST TO THE RIGHT TO TIGHTEN!)
Repeat this process again for the second grove imprinted on the same coupling. When the clamps are properly tighten the coupling should not lead to any leakages.
