Step 23) Attach the Wellhead<\/h2>\n
After the well has been built, cut the CMT tubing to the final elevation. You may choose to finish your CMT installation above ground surface. If so, you can leave the CMT stick-up as is and install the standard wellhead register or “house” the CMT inside a cut length of 2″ dia. PVC riser pipe (not supplied). <\/p>\n
If housing in a PVC pipe, first slide the PVC pipe over the CMT stick-up, and push below the final elevation of the CMT. Slide the wellhead base over the tubing and onto the PVC pipe. The wellhead base provides a tight friction fit on the PVC pipe. <\/p>\n
Slide the wellhead register flush with the end of the CMT tubing. Align the stamped number one on the register with the Channel 1 identifier marking on the outside of the tubing. Secure the wellhead to the CMT tubing by tightening the hex screw on the side of the wellhead register using a 1\/8″ Allen key. Bring the PVC pipe up so the register seats in the wellhead base (Figure 24). Grout or cement the PVC pipe in place. <\/p>\n

Optional Flow Control Monitoring Assembly<\/h2>\n
Under flowing artesian conditions or for vapour sampling, the CMT can be fitted with a flow through seal assembly (Figure 31) to allow the user to collect a sample, measure hydraulic or pneumatic pressure, and prevent uncontrolled flow from the well.<\/p>\n

The flow through seal assembly is tightened using a 11\/32″ (9 mm) spanner. Once tightened, press down on the black ring while pulling up to remove the red plug. Then push the 1\/4″ OD tubing into the fitting, which creates a leak-proof seal.<\/span><\/p>\n[\/et_pb_text][et_pb_image src=”https:\/\/www.solinst.com\/wp-content\/uploads\/2024\/11\/fig26-cmt-wellhead-manifold.webp” alt=”figure 32 solinst cmt multi-level system flow through seal assembly installed in wellhead manifold” title_text=”Figure 32 – Solinst CMT Multi-level System Flow Through Seal Assembly Installed in Wellhead Manifold” align=”center” _builder_version=”4.27.2″ _module_preset=”default” width=”35%” width_tablet=”35%” width_phone=”35%” width_last_edited=”on|desktop” global_colors_info=”{}”][\/et_pb_image][et_pb_text _builder_version=”4.27.2″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n
