Waterbox 130.4 plumbing.

[dzel]

Wondering what others are using for plumbing. I have an older tank that doesn’t have plumbing. I called waterbox and the kit is $250. Before I go that route, what are other using if they went aftermarket for plumbing. Mostly, what bulkhead sizes are to be used? Their website says two D25 and one D20

If I remember correctly, D25 represents a 25mm diameter (1") pipe. Meaning the bulkhead will accept a 1" PVC pipe. D20 would be 20mm...
