Look up the "durso" keyword. Allglass tanks come with nice durso pipe.
This pipe does not gurgle as much as the typical one...
You can buy guts to the Allglass overflow as a separate kit.
It might match your tank holes.

I have a Stockman pipe on there now that I constructed mysel.

Watch for the internal pipe diameter in DIY projects...

Have you used thin-walled PVC or regular SCH40?

SCH40 1" pipe has very thick wall - its internal diameter,
where water flows, is similar to thin-walled 3/4 pipe.
Replacing regular schedule 40 pipe with thin-walled
one and THE SAME OUTSIDE diameter will make a big
difference in the amount of water the pipe can handle.

You have no pressure up there, so using pipes rated
at 250PSI does not make too much sense...

Your Rio 1700 pump at the 4 feet hight delivers only 325 gph
Your 1" overflow should handle a much more!

My Quiet One 3000 delivers about 600 gph at 4 feet and my 1"
Durso stand pipe from Allglass is handling it with NO PROBLEMS.
