In response to Re: Why do they call it a "street elbow"
The thing left out of the expanation was that the water and gas mains were usually located in the street, so that is the reason they were called "street" ells.

: I was told this many years ago when I asked the same question.

: Back in the good old days before tapping saddles and corporations were used to connect water lines from the mains to the water meter, direct connections were made.
: A hole was drilled in an unpressurized water main, then tapped, and finished with an elbow threaded in the water main. These elbows had a short nipple then elbow pointing to the future meter location. The hole usually was tapped right on the top of the water main so a short nipple to elbow was used for start of the future service line.
: Street El's were developed to have 1 less threaded joint exposed to dirt for corrision. It also had a lower profile from snagging when the water main was dug up for repair or more service line additions.

: This was the general idea I was given many years ago.
