I agree. Also consider the "resistance" of the pipe, more so the longer the pipe is. > In my former house in Indiana I had dual sumps, both with > submersible pumps that went into a 2” PVC “Y”, up roughly 10’ and > out the side of the foundation at ground level. > If both pumps went off at the same time, which was certainly > possible during times of heavy rains, there was no way both could > push their combined rated capacity out through the 2” pipe.

For what it's worth, a 3" pipe has more than twice the flow capacity of a 2" pipe. > This setup had a double whammy - the volume of the pumps exceeded > the capacity of the 2” pipe, AND, the 150’ run of pipe from the > house to the catch basin couldn’t handle the capacity of both > pumps due to the restriction it presented. Was it adequate for just one? If so, then a 3" pipe would be sufficient. But if it were my house that would be getting all wet, I would oversizes, overbuild, and over-engineer. *grin* _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
