Plumbing a 120

[Mad Zoas]

Hard plumbing a 120 for the first-time. In regard to the bulkheads, I'm looking to use 1'' PVC what size bulkheads do I need? I perched 1'' bulkhead for 1'' PVC but the bulkhead was too small.

Too small for what? Do you already have holes drilled?

 

[Mad Zoas]

Yes. it has a center overflow with 4 1 1/2'' pre-drilled holes

If hole is really 1 1/2….
A 1” abs bulkhead needs a hole a lil bigger than 1 1/2”. It’s 1.65

3/4 bulkhead will fit.
