ASME Code Compliant Monitoring

The ASME code states: “3.18.3.8.1 Cylinders buried in the ground shall be protected from corrosion due to galvanic or electrolytic action, salt water, or other underground conditions. 3.18.3.8.2 The methods specified in 3.18.3.8.3 shall be considered as acceptable, provided that they (a) are designed and installed with means for monitoring and maintaining them in accordance with recognized industry standards applicable to the methods” 

The JACK-IT® meets and exceeds all requirements from protecting the jack from electrolysis as well as the environment from leakage.

To meet the requirements for the monitoring the jack, the installers commonly use the dip stick method by lowering a line inside the liner and observing whether the line indicates any type of leakage. The JACK-IT® product has been used across the country as an alternative solution to rigid PVC by elevator companies along with the dipstick method to meet the code for monitoring.

The dip stick method alone with the JACK-IT® satisfies the codes standards for monitoring. No other pressurization of the liner is needed along with the dip stick method to meet the code. This has been recognized as an acceptable method and is an accordance with industry standards.
Suggested Monitor Testing - Below The Water Line
  • At the top of the jack and the JACK-IT – insert a fish tape into the PVC pipe down the entire length of the pipe and the jack
  • Keep the fish tape in the pipe for a few minutes.
  • Pull the fish tape out and inspect for dryness. If the tape is dry the inside of the liner has no holes or leaks.
Suggested Monitor Testing - Above The Water Line
  • At the top of the jack and the JACK-IT – insert a fish tape into the PVC pipe down the entire length of the pipe and the jack
  • Keep the fish tape in the pipe for a few minutes.
  • Pull the fish tape out and inspect for dryness. If the tape is dry the inside of the liner has no holes or leaks.
Suggestion To Seal JACK-IT Before Pressure Testing
  • The top end of the liner can be double hose clamped (worm clamp) off above the air valve; we suggest the use of a sealant between the steel casing and the liner at the clamp area.
  • Sealant could be a silicone base or rubber cement. Allow time for the sealant to cure before proceeding with the pressurization. This will ensure the top is air tight.
  • Stainless steel banding (same as above) with an additional piece of JACK-IT material under the banding to eliminate the band from cutting through the liner.
  • Seal using a steel pipe clamp, similar to that used on ductile iron pipe with an o-ring or rubber sleeve insert. Sufficient to fit the diameter of the JACK-IT.
Note: all clamping systems to be above the air fill point.
