I am currently in the process of hard plumbing my Waterbox 35.1 and while I have seen a few other posts about this, I haven’t found one specific to what I am looking for.
I believe the 35.1 has a different return pump setup than the rest of the marine series. There is not a normal bulkhead like you see on the larger set up.
The bulkhead looks like this:
There is no nut that tightens it down it is just a male and female threaded fitting with a gasket on the inner (tank) side and an o ring on the other.
I have been struggling to find the threaded metric fittings to make this work. I realized today that the barbed fitting might be a 20mm “pipe” right above the barbed part.
This is standard 3/4 inch pipe over the barb and it lines up almost perfectly with the diameter of the “pipe” section. Can anyone confirm this?
If I were to get the Reef Octopus metric to standard conversion fitting, would it slide right over this?
