What are JM Eagle’s recommendations for joining PVC pipe?

JM Eagle™ recommends that our pipe be installed such that the assembly line on the spigot is even with the bell. This also provides greater ease of inspection when verifying proper assembly from the top of the trench.

A joint that is assembled per our recommendations will exhibit a gap, in which the beveled end of the spigot is stopped short of being fully bottomed out in the bell. This gap should be in the allowed tolerance of ½” to 2.5”. Studies have shown that this gap poses no significant effect in terms of head loss or clogging, and is supported by a proven history of fully functional lines. Although bottoming out the spigot into the neck of the bell may yield a joint that appears more attractive when televised, this joint is also more likely to exhibit leakage or breakage due to loss of flexibility or stress from over assembly. By assembling the joint so that the reference mark (or assembly mark) is even with the bell, typical variations in the field can be accommodated. The variations may result from expansion or contraction of the pipe, or the variations may result from deflection at the joint due to soil movement in the trench.

For pipe deflection during installation, please refer to individual installation guide per respective pipe.

JM Eagle’s procedures for installing Rieber and non-Rieber gaskets:

If you have received a combined shipment of JM Eagle™ pipe that contains both Rieber and non-Rieber gaskets, please note the following: non-Rieber and Rieber gaskets adhere to the same standards for the various types of JM Eagle™ pipe. They are both of superior quality and JM Eagle™ will stand behind them with a 100% warranty provided you follow our recommended installation procedures, which are:

1. When installing JM Eagle™ pipe with the same type of gaskets, which means Rieber to Rieber pipe or non-Rieber to non-Rieber pipe, you should use the reference marks on the respective type spigot ends.
2. When installing two different types of gasketed pipe, JM Eagle™ makes the following recommendations to account for the fact that the Rieber joint has a longer bell and reference mark when compared to the non-Rieber pipe:
• Non-Rieber Spigot to Rieber Gasketed Bell
  Follow the non-Rieber pipe reference mark at the spigot end.
• Rieber Spigot to Non-Rieber Gasket Bell
  Do not insert the pipe all the way to the reference mark on the Rieber pipe spigot end. Instead, use the reference mark that is shown on the non-Rieber pipe. This will require some measurements from JM’s non-Rieber reference mark.

By following the above recommendations, Customers will not experience joint problems such as over-assembly, damaged bells, or cracked bells.
Note: The minimum recommended temperature of PVC pipe during installation should exceed 40 degrees Fahrenheit.
