PVC Pipe Bell Direction

Posted By John Houle on Dec 8, 2016

Questions sometimes arise about which way the bell should be positioned in a PVC pipeline. Typically there are two concerns:

1. Does bell direction make a difference in pipeline hydraulics?

2. Does it make a difference during installation?

The answer is “No” for hydraulics – bell direction does not affect hydraulic design.

The answer is “Yes” for installation – bell direction is important during pipe installation to facilitate problem-free joint assembly.
