Plumbing Question

[Ben Pedersen]

I wonder why they don't make one. Seems like a niche product opportunity

1" is fine for water input into the frag tank but I wish I could find something at least 1.5" for water out. 1" seems narrow to me.. scary... I guess I will have to find a different bulk head and attachments.

I’m not a plumber, but if I understand it correctly, it’s because the threads for plumbing fittings and the threads for a nut to secure a bulkhead have to be designed differently to be effective. Threads in a plumbing fitting get progressively tighter the more the fitting is screwed in. The threads for the nut to secure the bulkhead can’t work like that, because the nut has to be tightened all the way against the glass.

That is correct. Threads for plumbing purposes are tapered.

That makes sense.. I had not thought of that before. They are tapered to create a seal.
