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 vari
