O. Inspection, Repair and Troubleshooting
1. Inspect the tubing connections and piping as the job
is completed.
2. Perform a final pressure test on the system after all
flooring is in place and building is ready for
occupancy to verify all joints are tight and no
damage has occurred to the tubing during
construction.
3. Repair of kinked or crushed tubing:
•
Use a copper pipe truer to restore the tubing
roundness.
•
If the damage is so severe that this cannot be done,
cut out the damaged section of tubing.
•
Cut a new length of tubing long enough to
span the gap.
• At each end of the splice section, install an
AlumiPex coupling.
• Slip a length of heat shrink tubing over each
end before tightening the couplings.
• Tighten couplings. Then seal them with the
heat shrink tubing.
• Route a groove in the subflooring deep
enough to accommodate the finished repair
section.
• Mark the location of any such repairs on the
tube layout drawing
N. Inspect Tubing Before Finished Flooring Installation
1. Arrange to inspect the installation a day before the
scheduled finished flooring installation starts.
q
Check the pressure gauge to verify the system is
still pressurized at or near 30 psig.
q
Visually inspect all tubing to verify there is no
damage.
q
Repair any damage you find.
q
Advise the general contractor of your findings and
release for finished flooring installation.
