Pipe Diameter Change

[stvnwhite]

Hello -

I have 1" line coming off my submersible but 1-1/4" line on distribution lines.  During an initial piping setup, does the CSV care if I go directly into it with 1" (internal threads) and exit with 1-1/4" (using the external threads) or should I transition farther from the valve itself ?    If so, on the upstream or downstream side of the valve?

Thanks

The CSV1A is dual threads so you can do just that.  Use either thread on either end.  Enjoy!
