Plumbing help

[fishkeeprian]

If my plumbing is 32mm how big will my holes have to be for the bulk heads? Thanks

Correct me if I'm wrong but that's a 1.25" pvc pipe. Look at the chart on the first hyperlink and then on the second hyperlink scroll down and it'll tell you what size drill bit you need. For a 1.25" bulkhead you need a 53mm drill bit
